Grand Prix :: 2001 SE 3.1 - Brake Pedal Goes To Floor / Fluid Low
Sep 7, 2013
I have a 2001 Grand Prix SE 3.1 that the brake pedal goes to the floor. I did notice the fluid was low , filled it up. I do not think it sucked air, although I can not be sure of that. As you can imagine, it is a beater so don't want to stick a ton of money in it. I had someone look at it that said he thought it was a "sensor" that would cost over 500 bucks. I don't know of any brake sensors at all. If there is, do they cost that much? If not would this be a master cylinder.

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.

I have a 98 gtp 2 door with the electronic dual zone climate control. I can't get air to blow much out of the floor vents. I applied vacuum directly to the actuator and air came from the vents fine. It seems there is a box behind the glove box that controls the vacuum to each actuator. My question is, would the issue likely be with that vacuum distribution box or with the electronic climate box itself.

Last weekend, I saw fluid under the right side of the car when in a parking lot and found a rather large puddle of almost clear, oily fluid on the garage floor when I got home. I figured it was power steering fluid. I just finished a rebuild a couple months ago but the old power steering pump wasn't changed, so I was guessing a leaky hose or seal.
I quit driving the vehicle. A much smaller puddle, barely more than a spot, appeared. But it was much nearer the front of the vehicle than the PS pump. And the PS pump fluid level is still full.
Not much evidence of dripping fluid in the engine compartment. Is it possible that the new motor mount installed just a few months ago cracked and leaked its fluid already? Don't know how I could verify that without removing the mount. I'm at a loss for the source of the fluid.

I have a 91 pontiac Grand Prix with a 3.1 and the car has NO leaks, however, I have noticed that the transmission fluid level go down and the engine oil goes up. My conclusion is that some how the tranny fluid is crossing over to the engine, is this possible? and if it is, how or where?
NOTE: my car has a tranny cooling line to the radiator but no engine oil cooling lines and the colant is clean. how is it possible?

I noticed red fluid coming out of a line behind the radiator. The line runs directly into the bottom of the radiator. Is that line the lower pressure or high pressure power steering line?

I have been working on my 01 Elantra for 2 days now. My problem is that I have absolutely no brake pedal at all, it just goes right to the floor. and this is only when the car is running, when it is off I give it a quick pump and i have a nice firm pedal. I installed a new master cylinder, bench bled it and all that jazz. I replaced the rear brakes and a wheel cylinder, I have also bled the brakes multiple times, and mutliple ways. bled the master while on the car and all the brakes while the car is off and while it is running. I dont know what else could be wrong with this. I looked at all the lines and there are no wet spots, no hoses are swelling up. everything looks top notch...i just have no brakes why.

Where does the 3rd brake light wiring harness plug into on a 2000 GP ? It's just hanging down and I don't see where it plugs into. I'm talking I'm the trunk area.

I bought a 2001 chevy malibu about a month and a half ago.when I test drove it,didnt notice any problems or leaks...after driving it for a 2 weeks...the brake pedal would drop to the floor while driving and then if I hit it again real quick it would be ok...this problem would happen now and then....we replaced the right front caliper thinking that it was sticking and bled all the brakes..There was air in the system..everything was fine for about two more weeks then while driving the pedal would get hard when applied and then drop again..not all the way to the floor,and it alternates that way..what are your thoughts? I don't have much money to fix this problem.

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.

My brake pedal goes almost to the floor when I'm braking.I replaced the rotors, pads, shoes, power booster and the master cylinder 3 times.Had it bled twice and I still have a soft pedal, but now it firms up a bit as I pump the brakes.

I have a '98 GPGT 2 door and just over this past winter the doors started to bind with the fenders. Is there a fix to this? I am afraid soon it will get so bad that it will bend the fender in. ( that happened to my wives '01 GP ).....

With summer heating up so is the engine. Temp stays normal at freeway speeds but as soon as I hit stop and go traffic it shoots up. Water pump is two years old. I flushed the radiator and didn't get much gunk out. Both fans are running when the AC is on. If I shut the car off but leave the key on the fans do not run when the car is not. I can't remember if they used to or not.

Over the past month, my car has been hesitating in 3/4 gear right around the 1900-2200 RPM range. The tach moves up and down (like a rev limiter) between that RPM range for a few seconds then it is okay. I notice it mostly when I get on the expressway. The car has 185000 miles and here is a list of things that I have replaced along with the mileage that I think might possibly be the issue:
Mass Air Sensor -163000
Tune up - 160000 (Plugs + Wires)
Fuel Filter - 145000
I checked through the forums and didn't see my particular issue. Thoughts on the issue?

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 just changed my fuel filter and now I am having issues with the idle/accelator. When I get the car going to a speed of 40mph for example, I let off the gas and the speed barely drops. Then when I went down a side street about 20 mph, I let off the gas and the car just kept going. The idle was initally high, but then dropped down to it's normal 800rpm.
The only thing I touched under the hood was releasing the pressure from the fuel pressure regulator before the fuel filter change. I just removed the idle control unit and cleaned it but that didn't work.

I was driving around today and had to hit the brakes really hard for the first time. ABS kicked in and during the ABS 'action' the brake pedal rapidly went to the floor. With each 'pump' the ABS made it felt like the pedal sunk slightly.
This was on dry pavement, a little gravelly / dirty and the car stopped rapidly, but just as I stopped the pedal was VERY close to the floor, and with just a touch more pressure it did in fact hit bottom.
Sounds to me like the ABS pump needs to be bled, is that right? Can I do that myself with a VAGCOM? I hate having the dealer do anything, even if it is their job. How to SAFELY confirm if cars does / does not do this as well?

I swapped my fluid and ever since I did that my clutch and brake pedal are pulsing/vibrating only when I start the car. It almost feels like ABS pulsing but on both pedals and the car is obviously stationary.
I followed the procedure from the manual and did all 4 corners and slave.
Brakes work fine/clutch is fine...
I must have done something to upset the BRAKE system?

2005 Volvo S60 T5, 90,000 miles. The brake pedal depresses almost to the floor. Dealer service has not had a solution to this problem. All brake components are supposedly nominal. Might pedal position sensor be faulty?

My 04 Camry is having brake issues. It has 205k miles. The front pads are great and the back shoes are great. (Drums in back) I've had them adjusted multiple times but my pedal still goes almost to the floor. It's not the master cylinder cause I've already replaced that. The pedal doesn't bleed off either. But I have bled the brake lines and there is no air left in the lines.
