Santa FE SM (2001-06) :: Brakes Pedal So Soft That It Goes To The Floor
Aug 21, 2014
I have a Hyundai Santa Fe 2005 2.7L 4WD ABS.
The problem is that the Brakes pedal is so soft, that it goes to the floor, and doesn't brake at all in first pedaling. I am able to apply brakes after pumping the pedal thrice in continuation and then when it builds up some pressure, then it brakes and I'm able to stop the car. Once, I take the foot out of the pedal, it goes bad again. Once, again if I have to apply brakes, I have to do 3-4 times pedaling.
The brakes are stopping the car fine when they get applied in 3rd or 4th pedaling and when pressure is built up. Its the pressure not getting built up or maintained in the first go.
What has been done by the mechanics to solve this:
1. Master Cylinder has been replaced with a new one. (This has been done twice)
2. Brake Pads have been changed.
3. Brake fluid has been replaced and is upto the brim in cylinder reservoir.

Here's the short of it. 3rd time in a year the brakes on my 2005 SF (177K miles, 2.7L) have gone out.
The brake pedal is very soft and goes to the floor before braking occurs. Typical signs of a bad master cylinder.
The first time was a year ago. I bought a re-manufactured master cylinder, change it and bled the brakes. Worked like a champ and lasted 10 months.
To months ago same exact symptoms. I assume it was a bad re-man part. It's under warranty, not big deal. I do warranty exchange, bleed system, brakes return. All is good.
Less then 3 weeks later, brakes gone, same symptoms! This time I spend the difference and get a brand new OEM cylinder with reservoir. Replace, bleed, problem fixed. Brakes go out in less than a week.
I'm not leaking anywhere. Reservoir is to corect level. ABS light is NOT on. No chattering in brakes. Braking is smooth both when power brakes work and when not. No visible damage to calipers. I'm 99% sure there is no air in the system, but I'm going to try bleeding again. I have not put it up on a lift to yet to check all the lines.

The pedal used to go right down to the floor and would barely stop the car from a crawl, in response I have bled the brake lines to all calipers, and checked the hydro booster fluid level, and with only slight improvement the pedal almost hits the floor.
I am thinking the brake master cylinder is shot. The pedal becomes solid after about 15 pumps when off, and holds pressure, when on it takes several pumps to build any sort of pressure and cannot be built up to the solid point, and looses pressure quickly when just holding the pedal down.

My 18 year old daughter has a 2005 Hyundai Santa Fe that I owned for 8 years before passing down to her. Just recently she was driving when all 4 brakes locked up and the brakes began to smoke when she attempted to drive it to a location where she could pull over. The pedal went all the way to the floor. ABS light is on. Had a tow truck bring it to my brother's house. The tow truck guy was able to back it off his truck and it stopped fine. Later when my brother test drove it, the same problem occurred. My brother replaced the Master Cylinder but it didn't work.

I have a 2005 Santa Fe 2.7 V6.
For over a month I have had a soft brake pedal. For those that may not know what that is, I push my brake pedal down 3/4 of the way, and I'll finally feel the brakes catch; however, I cannot stop quickly. I have had to use the Sports Mode to slow down my car many times.
I brought it to my local mechanic and he has done the following:
1) he thought it might have been the master cylinder, so he replaced it. he checked the old master cylinder and found nothing wrong.
2) bled the brake system a couple of times, but it still came back
3) brought my car to the local dealer to drain the ABS system. The problem still came back.
I waited over an hour as the dealership's service department checked out the car. Someone finally came to me and said they checked the lines and they are not leaking, so it has to be the master cylinder. I told the guy that it's a brand new cylinder, and when the mechanic looked at the old one, he said there was nothing wrong with it. All he could say was it's not the lines, it's the cylinder. If I had the problem before & after the master cylinder was replaced, & nothing was wrong with the original master cylinder, how is it the master cylinder?
I called my local mechanic on my way home from the dealership and told him what happened. He said he was going to do some research, mentioned something about replacing something with the ABS and he would call me today.
I searched the forums for brake issues and saw something about cracked ABS rings. Could that be an issue? Could it be something else?

Soft Pedal. 2004 Santa Fe, front wheel drive 4cyl, 2.4l
When I first owned this Santa Fe the brake pedal was high and had lots of stopping power, over the last few years I noticed the pedal was getting lower. I have replaced everything needed thus far including pads, rotors and everything has recently been serviced front/rear/emergency brake/ calipers and still a soft pedal. Had the guys in our recon shop replace master cylinder and bleed the lines a few times with a full week in between bleeding to ensure there was no air in the lines. The mechanics are stumped but I'm wondering if we missed something...... I still can stop no problem but there is no grab in brakes until pedal is half way down to the floor or worse.

My B6 purchased exactly three weeks ago has had a soft brake pedal since day one. By "soft," I mean that when parked with the engine running and applying moderate pedal pressure, the brake pedal provides some resistance but sinks to the floor. If I pump it up a few times, it temporarily gets much firmer, but eventually sinks to the floor again after a few seconds. Now the car so far has never failed to actually stop, and it can get into the ABS. But during an abrupt (okay...panic) stop last week, it did go to the floor while the car was still moving. That's when I decided that was enough and took it back to be serviced.
My expectation was that there was just a small amount of air in a line somewhere, and that they could bleed the system and fix it. That was my experience with my B5: it was very sensitive to the least little bit of air, and if it wasn't thoroughly bled after brake service the pedal often got mushy and could find the floor. But bleeding them always get the pedal back to normal. So the service advisor said that he "had the service manager drive [my car] and compare it to a new Passat [on the lot] and talked to "Quality Tech. Manager to confirm." And the confirmation was that my brake system is "working as designed." In short, they say the brakes are working properly and there is nothing to fix. So I have now picked up the car and it still does the same thing.
Now I can (and will) bleed the brakes on my own over the weekend. But I would like feedback from others as to whether or not their brake pedals regularly see the floor. I just can't see this being the way any hydraulic brake system should work..

I have a 2004 Ford Expedition and today on the freeway I had to step on the brakes pretty hard to avoid an accident. After pressing, the pedal resistance became really soft and the brakes worked, but were very sensitive (a lot of pedal movement to brake). I had this happen some time ago and I did a complete system flush and no problems since then, but it has to do with how hard I hit the brakes. What could be wrong????? BTW - I never noticed the anti-lock brake pedal pulse at all during this event. I'm not even sure it is working at this point. No dash lights to indicate an error of any sort.

I've got a 2001 Excursion with the 7.3 and while out driving around on Friday I noticed that my brakes were gone and when I pushed the pedal it went straight to the floor. I pulled over and put in brake fluid (it was empty) and managed to get home. I have discovered that the brake line (it is metal) that runs from the front to the back is rusted out and the brake fluid is just pouring out of it. What is the part called? I spent about a half hour looking for that particular schematic on the ford parts web site but couldn't find any mention of that brake line. Here is a picture. There are 3 metal lines and one is leaking the brake fluid? Can I fix it in my driveway or should I have it towed somewhere?

I have a 2000 Grand Prix 3.8 with 65,000 miles. Bought the car new for the wife to drive. The front brake lines rusted out. My wife has a friend who is a backyard mechanic. She had him replace the front brake lines, from the abs block to each front wheel. Well she finally told me that the brake pedal is not right. I went out and sure enough with pressure on the pedal it goes to an inch off the floor. I bled all for lines at each caliper, no change in pedal. I bled almost a full bottle of fluid. You can pump the pedal for 10 minutes and no change in the pedal. I don't think it is air in the line. I changed the pads and rotors on all four corners last fall. The brake pedal was normal then.

2001 F-350 / 7.3L / 147K ... What are some symptoms of the master cylinder going out? And is there a such thing as a rebuild kit anymore? The pedal has been getting spongier & spongier over the past months. Truck still stops O.K. but you have to brake earlier than I used to. Pedal can go almost to the floor. Pedal continues to go to floor as pressure is applied. Does not go to floor though.

I changed front rotors and bled brakes. They were hard for a few days and went soft. No leak in fluid (MC reservoir is still full). No leak in fluid near any wheel. Could I need to bench bleed the master cylinder?

So for the last month when I hit the brake pedal I've been getting a creaking noise in the pedal and the brakes don't seem as good. Within the last 6 months I've replaced the rotors, calipers and pads on the front and back. Starting last week when driving between 0-40 mph the ABS has started to engage on its own without even touching the brake pedal. So I've pulled the 2 ABS fuses and I no longer have the creaking noise when hitting the pedal and of course without the ABS its no longer engaging on its own. I've checked both the tone rings in the front and both of them are fine. I also now have a cel with code 0501 and I'm guessing that is because the ABS is currently disconnected. Is it safe to assume that the ABS Pump also known as the hydraulic electronic control unit has gone bad and needs to be replaced?

I just joined as I bought my '97 F-150 5.4 4X4 about 3 months ago. The dealer gave me a 6 month warranty but hasn't honored it at all and I've had one problem after another. That's another story though but right now I'm just trying to fix the important issues. The problem at hand are my brakes.
I was noticing a couple days ago (maybe I never noticed it that much as it was a new vehicle to me) that when I apply the brakes it sounds like a bicycle pump and the pedal travels nearly all the way down. It doesn't hit the firewall but I'd probably guess it has 3 more inches or less until it bottoms out. The hissing only occurs as the pedal travels and stops when the brake pedal isn't moving.
Now I'm not sure if the hissing sound is normal as I replaced the brake booster (from the junkyard though) and the new one still hisses when I apply brakes. The brakes seem to work okay, could be more sensitive it's just the pedal feels soft until it almost bottoms out like I stated before and the the brakes grab a little bit harder. What could it be?

Got Elantra GT 6 month ago. Good car, but it seems I have a very common problem of Elantras - lost of brakes. My car has TCS, but no ABS. It started 4 month ago. Car is fine for several weeks, but then within two days brake pedal getting from bad to worse. My mechanic already replaced master cylinder and right rear caliper. Did not work. Yesterday it was third time when I almost (very soft pedal) lost brakes. Today in Hyundai dealer service they bled the brakes and said "that they hope it will work". Their mechanic found air in both (left and right) rear brake lines. So, my question if I have a leak in, say, left line will it propagate to the right line? I am asking because I do not know the hydraulic schema of the brakes and want to collect as much info as possible.

I have a 2001 Dodge Durang. 105k miles.
Brake pedal is real soft goes pretty far down (close to floor) before brakes kick in.
Check front disc pads and rear shoe pads, both look good. Fluid level is good. Bleed brake lines.
Pump brakes up when car is off, pedal is real firm till I turn car on an push on brake pedal right to the floor.

Bought a prius off craigslist that didn't have a hybrid battery. Replaced it with a used reinvolt battery off ebay. Car starts right up now. However, there's a few things wrong with it. I can't get the key out of the ignition and the brakes are soft. Could these be related?
I have a fully charged and known good 12v battery in the car. And when I remove it, the key comes right out. If I bleed the brakes, do you think that will solve the problem?

I give up. I have been trying for a very long time to get the brakes on my 1936 dodge to work with no results. The whole system is rebuilt, new lines, resleeved and rebuilt wheel cylinders, rebuilt and resleeved master cylinder, no leaks in system, pressure bled, vacuum bled and new lines. I even had a mechanic try and get them to work. He said all they needed were to be bled very slow. he actually got them to work slightly but after the car sat for a week the brakes were gone again. Drums all around, master cylinder is single cylinder. Brake pedal goes right to floor.

I flushed my brakes this afternoon and all went well until I got in and found a red series of lights on the MFI stating "brake fluid". I touched the brakes and there aren't any. I pumped them 50 times or so and still the pedal goes all the way to the floor board. I used a machine I have used on countless other cars and have never had a problem before. I used VW brake fluid. The brake fluid container is right at the max line. The only thing that was different compared to the other cars I have done is that the Treg has two bleeders, one on the front of the caliper and one on the back. I called a VW service consultant and he told me they use the outside one to flush the brakes and so that is what I did. My only guess is there is air in the system. But, I am not sure at all how that happened.

I bought a 97 f150 4x4 last week. I was cleaning the frame up with a wire brush on a grinder and accidently cut one of the front brake lines. Seeing how this truck has only 100k on it and all oem stuff on it, I decided to replace the front brake components, calipers, pads, rubber and steel lines. Got it all back together and bleed the air out of the front brakes. But the pedal still goes to the floor. I can pump them up with the key off but when i turn it on the pedal goes to the floor. I did not bleed the back brakes becasue I assumed that the master cylinder would be divided and independent of each other- back and front. So it this just that the back brakes needs bled or do I have another issue like bad booster- everything was working well before I cut the line?
