Ford F-150 - 1997-2003 :: Spongy Brake Pedal?
Nov 6, 2015
I just finished replacing pads, calipers, rotors, wheel cylinders & brake drum hardware on my truck along with flushing the brake fluid. The brakes work but the pedal goes almost to the floor. While bleeding them some air did come out as expected. But a couple times the master cylinder reservoir got very low on fluid. The workshop manual talks about bleeding the MC but are special fittings needed for that?

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??

I replaced all the brake pads on all 4 wheels. Pretty standard procedure. I now have a very spongy brake pedal. It stops but the pedal will be almost to the floor. I did not break any of the lines open during the procedure just used c-clamp to spread the calipers. No ABS light. Have a Snap-On power bleeder and bled the system several times with no change. Checked the power steering fluid level and inspected entire system for leaks.

My dad drives an '06 Sonata. And he recently broke a brake line and had gotten it fixed. His current problem is that his brake pedal hasn't returned after getting the line fixed. What can he do to fix that? The pedal is really low and is spongy. And his ABS and ESC lights are also on.

I have a question about the bleeding the brake? When I washed my E, I usually spray the wheel and the brake part. I don't know it is a good idea or not. Recently, I felt like I have to step further on the brake pedal to apply the brake.
The force is there and Brake assist is still in effect if I step fast enough. I just felt like the brake pedal is spongy. My E is on 36k right now. Do you think wash the wheel often will cause the problem to brake line?
I have confirmed that my Gf's Elantra is easy and ease to brake than mine. At the mean time, her brake fluid is darker than mine. My brake fluid is full and clear. Maybe I should not wash the wheel more often. Or maybe I get OCD too much?

I noticed last week that my brake pedal seemed more spongy than usual. The next day the pedal would go down about half way to the floor before I had pressure. And then the next day the pedal would go straight to the floor. Pedal comes back up once released. I still have brakes pressure about an inch before the pedal bottoms out. Its been like this a couple days now. The vaccum pump works fine. I'm gunna try bleeding the brakes on it tomorrow.

I have a 2000 Silverado 1500 replaced calipers, master cylinder, and ABS Pump/Modulator. Bled all four calipers. Brake pedal spongy and has very little pressure and travels all the way to the floor. What am I missing here?

Drove the lady's car out on some errands today and ran into a problem on our drive home. Car was pinging really bad (low rpms in 1st and second) and car seemed as if it couldn't get out of its own way. Was driving for some time on the freeway (after a blistering 0-60 time of 20 seconds ), and noticed that the brake pedal was really spongy (felt like a mk1 when you try to brake with the car off). Found that the e-brake handle was up (negligibly up (perhaps 1mm raised)). Didn't have power brakes at all and had to use a lot of engine braking to slow the car off of the freeway.
Rear of the car smells like copper (wet pennies) and found that the brake reservoir is cracked (but fluid still at max level). Also noticed that as of late, when the car is at a stop (sometimes in gear, and sometimes in neutral) the car will rock/bump a little almost as if someone were giving it a bumper kiss with their car.

My Gen I Prius is screeching at me with the BRAKE and ABS lights on, and I hear the electrically actuated pump pulsing as it tries to get pressure into the system. The pedal is spongy and will go all the way down, with the right amount of exerted pressure from my foot.

After my local brake shop changed the front rotors and brake pads on my 99 grand cherokee the brake pedal is spongy and long, almost reaching the floor. They don't know why. Apparently they had a problem with fitting the new pads. I took it to the jeep dealer and they told me the master brake cylinder was leaking and needed to be replaced. many hundreds of dollars later the brakes are still spongy and long and does not correct with repeated pumping. The dealer was also stumped and I complained that nothing changed with the new master cylinder. what might be the problem?

2009 XRS ABS brakes .... I changed all four brake pads and flushed out most of the old brake fluid. Bled all four sides. But now while I am in idle (like waiting for a light to turn) my brake pedal is spongy and is making a hissing sound. All was good before I did this job.

I have a 2003 F-150 supercrew 4x4, was having problems with the brake pedal going to the floor, had replaced the front calipers, master cylinder and the brake booster. I have blead everything out including the rear calipers even though I didn`t touch them, the truck stops but the pedal isn't what it used to be, even when the truck is off the pedal has a tendency to go down, there is nothing leaking and not losing fluid, don`t know what else to do?

I have a 1998 F 150 extended cab and the brake pedal is low. The front calipers and rotors were replaced last year because the left front caliper froze on and smoked the pads. I also replaced the brake booster and master cylinder because the brake booster showed signs of leaking vacuum. The whole system has been bled completely twice. After each bleed, the pedal was high and firm.
I have not found any sign of leakage and the fluid level looks ok and unchanged. The rear brakes look ok, but no work on them in last few years. Mileage is 198k. I had to hit the brakes hard on a muddy road a few weeks ago and the truck stopped straight, so the ABS seems ok. The problem is that the pedal has dropped down a few inches from where it was then the system was bled out. What to check next?

Ive got a 2002 f250 Sd 4x4 with 93000. Im getting severe vibration from the front drivers side at highway speed. I thought it might be a warped rotor but i cant feel it in the brake pedal, when I put the brakes on. How can you tell when the hub bearing assembly is going bad? The truck doesnt pull to that side either. I can hear it, and feel it more when i'm going around highway corners. When im driving through town, I can hear a "clunk,clunk,clunk" noise coming from that side also.

The brake pedal intermittently goes to the floor on my nephew's 2003 F150 without grabbing at all. Pumping the brakes restores them, then they act normally for a while. I've replaced the master cylinder with a new Motorcraft unit, no change. No ABS codes. All rubber lines are in good shape. I'm stumped, although I suspect the ABS system somehow. I'm going to have him pull the ABS fuse and see if the problem goes away.

2002 F-150 4x4 w/ 5.4 v-8. Brake pedal goes half way to floor before it starts to stop the vehicle. I have replaced and bled the master cylinder, bled out all of the calipers, and the calipers are installed correctly because the bleeder screws are at the top on all of them so no air can be trapped up there. The truck seems to stop fine, but just takes more pedal to get it to start stopping than I'm comfortable with. Could the ABS unit need bled out too? Or could it be an adjustment issue with the booster rod?
Also, something else I noticed, and it may be related..the ABS unit usually makes a slight clanking sound (like someone kicking a metal garbage can) a couple seconds after the key is turned on. I know its the ABS unit because a couple weeks ago I had a friends scanner hooked up to the truck, and I went into the ABS computer to clear the codes (have ABS light on from what I found to be a bad sensor wire on the front drivers side according to the scanner) and as soon as i cleared the codes on the ABS, it made that sound. I don't know if maybe there is something wrong with the ABS actuator, or if it's related to the brake pedal issue.

I have a 2000 SCrew KR F150. A couple of weeks ago I noticed the brake pedal was slowly going to the floor while at a red light. I pulled over and popped the hood checked the fluid reservoir. It was full, so obviously no wheel cylinder issues or fluid loss. I haven't had a chance to tear into it yet.

I have a 99 f150 and it won't shift out of park. The taillights work and I tried to turn the key forward and move shifter to neutral but it didn't work. Is it the switch on the brake pedal or the interlock solenoid by the shifter?

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?

Last week my brake pedal started going to the floor when I stopped, it still stopped and felt fine on the top half of the pedal travel but then it would just slowly fade to the floor. I took it to a local shop and they said the master cylinder was leaking internally and my rear brakes were shot. I have 75,000 miles and the rear brakes were original so I told them to fix it. This is basically what I expected it to be.
They kept thinking they were getting defective master cylinders but after the two Napa parts and two Carquest parts they realized they misdiagnosed it and said I needed to take it to the dealership. I paid for the rear brake job since it needed done anyways and have an appointment for next week at the dealership. What might be causing the problem? I see no brake fluid leaks, no vacuum leaks, the booster was replaced 25,000 miles ago due to noise, no ABS light on, no CEL on, no other symptoms.
