Ford F-150 (2004-2008) :: Brakes Get Spongy / Brake Fluid Level Low / Dash Light Comes On
Feb 21, 2014
I started to feel the brakes get spongy. So I pulled the master cylinder forward and turned the 7mm about a half turn. Also noticed the brake fluid level low. I topped it off. Drove down a steep hill....red dash brake light comes on.....plow truck stopped at the base of hill with on coming car. Used emergency brake.
The down side is that I don't have a dry area to pump and check where the leak is. The up side is I have a 2nd car to drive (yaris).....the truck only has 45k miles on it. Where is that area that is prone to leakage on these trucks....... 2004 heritage 4.2 v6 with stick shift.... only 45k miles ....

After replacing the Front Rotors, calipers, and brake lines on my 2005 F150 Super Crew I have spongy brakes. I have also replaced the master cylinder. I have bled the brakes as well as a reputable repair shop has done the same. We are both at a loss as to what is wrong. The ABS light is on now after the replacement of these parts. This issue did not exist prior to changing these items. This was done to hopefully eliminate brake shudder that I have been experiencing for some time.

Just bought a 2007 supercab with the 5.4 in nice shape, but have an intermittent brake light on the dash. (No ABS, just the brake light.) Our mech. diagnosed a bad Brake Fluid Level switch. I can get a new sensor. I'd like to try and replace this myself and save a lot of money if it's not too difficult.
I'm looking for some clear step-by-step directions on doing this, and have a couple of questions:
Do I need to disconnect the battery first?
Do I need to empty the brake fluid reservoir? (Looks like the sensor is in the bottom of the reservoir, if I take it out without draining res, will I have a mess?)
When looking up the sensor online, I also saw the plug/connector for sale, should I replace that as well?

I just replaced the front break pads. I didn't replace the rotors or get them machined, didn't look like they needed them. Once I pushed on the brakes (truck off) I noticed that brake fluid spilled out the brake reservoir. I'm guessing it happened when I compressed the piston into the caliper? I took some of the fluid out of the reservoir and now its at MAX (I didn't bleed them). I've only been only be able to stop and go on the driveway (I'm waiting on a new radius arm bracket). The brakes seems spongy, the brake hits the floor. ABS and Brake lights came on then turned off once I started to pump them when I turned the truck 'on'. Do I just need to actually drive and "break" the breaks in?

I bought an 04 F150 SCrew 5.4 3V a while back. The power steering fluid level keeps dropping. I have topped off the power steering reservoir at least 3 times in the last month and a half.
What's got me baffled is I can't find evidence of a leak anywhere. The hoses, the pump, or on the belt. I've crawled over & under it. I can't find anything anywhere.

I recently purchased an 07 f150 lariat leveled 4x4. I noticed the other day that all at once, the abs light and parking brake light came onto the dash, 4x4 low doesn't work and just stays in high and the ac doesn't blow cold. I'm assuming this is somewhat connected considering this all happened at once but really just not sure.

So my 2007 Accent/Hatchback started having this weird issue the other day.
My Parking Brake/Low Brake fluid Level Warning Light will coming on while driving and then all the gauges drop down. The light goes off and the gauges come right back up. All this happens within 2-4 seconds maybe. And usual happens maybe once every 6-7 times I drive it so not all the time.
I am driving, not braking so even more confused.

Yesterday the brake warning light came on in my 13 350. I checked, and the fluid level in the master cylinder was at the "min" line. I don't think I've ever had to had brake fluid in any car before. Seems to be Ok today, but I was wondering if other folks have had this happen? Of course if it happens again I'll have to check the brake system. Just wanted to check.

I have a 2008 Ranger Sport 4x4. I noticed yesterday that when I stepped on the brake pedal it felt like nothing was there until I step a little harder then it was like full brake application. The truck only has 63000 on it. Then every once in awhile it would be normal ie very light brake application and slows like it should. Then back to same issue... Any thoughts about this??

About a week after my wreck I got the Parking brake light and the message brake fluid level low. The fluid level is fine and I read some other threads where people said the vacuum system was connected somehow. I knew the ESOF didn't work so I replaced the broken line and nothing changed, except the ESOF works now.
Anyway I can't for the life of me find a replacement sensor, part number or anything.

What are the odds of the brake fluid being low, and not being indicative of a leak, in my new-to-me 2012 prius two? It's at the "low" line. The dealer said they put all new brakes on it before they sold it to me as pre-owned & certified, so the low fluid level shouldn't be low because of related brake component wear.

Brake issues 2003 f250 super duty 6.0. Changed master cylinder, drivers side rear brake hose, new pads all around. Pedal is good at times for a few seconds. I've bled them all numerous times truck running or not flushed power steering pump new fluid. Brakes are spongy or go to floor. Do I need a scanner?

I'm not too familiar with these trucks, but I've been working on my buddies 1999 e350 ford van.
The other day we were going out kayaking, and the brakes locked up, we were able to drive it home, but it was obvious the brakes were holding the truck back. decided to check it out today, found one front and one rear caliper were sticking, the dual piston calipers only had one working, which I believed to be causing the pads to get pressed together crooked, and caused them to "lock up" or get stuck.
anyways, got the new calipers on and no more sticking, so I bled the brakes started in the front and went all the way to the back, did every caliper. brakes feel firm with the vehicle off, but instantly when the van is started, the pedal goes to the floor. it still stops okay, but the pedal feel is not nearly where it should be.
I got all of the air out of the system, but the abs light is on, and has been for a while. I'm wondering if there is something else that needs to be bled in the abs? someone was telling me about bleeding the abs motor?

I only get a brake warning light when it is below 40F and I take a turn. It then goes off by itself. I suspect the brake fluid level sensor may be going off. But when I looked, I didn't see a 'float' sensor.
So today the cold soaked car showed midway between Max-Min. Ok, top it off and drove to parts store only find it was just over Min. Lesson learned, check AFTER driving.

The brake light came on randomly yesterday, flashing foe about 5 seconds, then shut off. Hasn't come on since, but I looked at the brake fluid resovior and the level is about .5cm (.2inches) below the "min" marker.
Can I just open the resovior, pour in the fluid, recap it and go? I remember hearing from someone that if you open the resovior cap at any time, air rushes in and you must bleed the entire system before you can drive again

I am a dedicated Ford truck owner. Both vehicles I have had are both F150's. My first one was a 5.4L v8 03 and my current is a 5.4L v8 06 4x4, seen below.
When I bought the truck it was straight piped. I went ahead and did a GOTTS mod on it. The truck also has the factory tow package. I replaced the spark plugs and engine oil (Amsoil High Mileage). I did a couple basic things like putting in the light bar and replacing the headlight housings. Other than that it it pretty much the same as when I bought it. I cleaned the throttle body and sensors, using the proper cleaners. I ran two cans of SeaFoam through as well.
With my last truck, I 'flushed' the transmission (not a actual flush, but I changed the tranny oil about 7 times in a short period of time). A buddy suggested I do it, as it was a DOT truck and maybe wasn't treated the best. It was a automatic, just like my 06. Would that do any actual good?
I have noticed that truck has a spongy/delayed throttle response. The engine idles normally and there are no codes being thrown. I had a similar issue with my 03 but it had a cable to the pedal and I just had to tighten that up and it was better. Perhaps because of the straight pipe and GOTTS and no tune?

I am having a problem with my 2004 Toyota Camry XLE V6 brakes. For the past couple months I keep seeing the brake dash light turn on and the brake fluid is constantly going down but I don't see any wet spots under the car. I needed rear pads so I kept thinking that it was just the fluid going down because of worn rear pads but I changed the rear brakes last weekend and still have this problem. Today when I went to drive the car for the first time of the day I heard this loud noise every time I stepped on the brake pedal. I checked the brake fluid level and it was a little below low so I filled it back up. I kind of feel like I've had to fully press down on the brake pedal lately to stop the car. There's plenty of brake power but I feel like I have to push all the way down and I don't remember it being like that.

After a routine brake pad replacement the brake pedal hits the floor when applied with normal force. The pedal feels like a badly leaking master cylinder, but prior to the pad replacement the brake pedal was firm as a rock with no drop at all. If I pump the brakes the pedal will come up to normal height, but if I then maintain light pressure the pedal will again sink to the floor.
1. Truck was braking fine, however pad 3/4 worn
2. Replaced front calipers, rotors and pads
3. Replaced front brake feed hoses
4. Replaced rear pads
5. Started engine
6. Started bleeding from furthest point from MC a) passenger rear, b) Driver Rear, c) passenger front, d)driver front. Did it two times...
Still, brake travels all the way to the fire wall and never develops tension. Moreover, sometimes, when person pumping brake puts pressure and i open bleed, no fluid comes out. Could it be a failed master cylinder??? I tend to think it's not because 24hrs ago, the pedal felt fine and the truck was braking ok.... So much for preventive maintenance.

Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. so I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work and worked in a shop in high school. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?

80km on my accent, the brake pedal was getting softer and brake fluid was a bit low as normal due to brake pads were worn up over time. Brake pads were never changed. I thought changing the pads would change the softness of the brake pedal. I changed the brake pads, left and right, the brake fluid in the reservoir went up as normal but I drove around but the softness of the brake pedal did not change. I still had a little less than half size on the old pads. I need to press the pedal a bit much to feel the brakes. I am wondering maybe the brake pedal was always like that when I bought the car.
