Ford - Clubwagon :: 1995 E350 Van - Brake Pedal Goes To Floor
Feb 15, 2013
After a recent front brake caliper replacement, the brakes work great except that when moderate pressure is continually applied to the brake pedal, the pedal goes all the way to the floor. While driving down the road, when the brake pedal is depressed, the brakes engage right where you expect them to, and the van stops just fine, even if the stop is extreme. There is no air in the brake lines. The front calipers have been replaced twice, the back brake cylinders replaced, the master cylinder replaced, the RABS valve replaced, all by a certified shop trying to address this issue.
I spoke with the service manager at a local Ford dealer in Seattle and he was aware of the problem and said that there is no solution. He said the brakes will work fine. He couldn't explain to me however, why this happens. If the van is not running, the brake pedal holds firm, so I assume the problem has something to do with either the ABS system or the power assist, but I can't say for sure. I can live with this since the van stops great. What is mechanically going on that allows the brake pedal to go to the floor even though the brakes are fully engaged after the pedal is depressed say a third to a half way down to the floor.

I have a 95 Accord EX, 4 cylinder with ABS. The brake pedal goes to the floor about once a month, all times of year (I'm in Minnesota). I had the brakes bled last summer, but that didn't work. The ABS light has been on for probably 10 years. When I talked to my mechanic he said the ABS system, even though it's not working, could be a cause of the problem because fluid is still traveling through that system. He said most likely a master cylinder, but no guarantees. He said it could also be one of the brake lines. About 120k miles on it. What are the odds that it's the master cylinder?

I have a 2000 E350 15 passenger Ford Van with 125,000 miles on it. I am burning a quart every 500 miles. The van produces a cloud of black smoke occasionally when I start it. Maybe once every 10 starts or so. It seems to be more prevalent when the van is parked with the engine downhill. About a year ago, I switched to high mileage oil. Could this be part of the problem? Or is there anything other than a rebuilt engine that will work?

I have a '99 E350 van that I am feeling a light anti-lock brake pulse in the pedal when I am rolling to a slow stop under light braking. Braking doesn't seem to be affected, but it doesn't feel right. I tried locking up the brakes and didn't feel any anti-lock pulse...seems backwards.

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 did a complete rebuild of my brake system in April. Drums, shoes, wheel cylinders, springs, hoses, pads, rotors, calipers, master cylinder, proportioner valve and flushed all the lines and refilled with synthetic fluid. I have made five trips from Southern California to Idaho hauling home furnishings, one trip to Oregon and one trip to Northern California since overhauling the brakes with everything working great. Now something strange is happening. The brake pedal goes to the floor with very little resistance. It isn't spongy like there is air in the lines. It just goes to the floor if you push it all the way down.
The truck stops ok but it is really scary with the pedal going down like that. You can feel when the rear brakes come on because there is a little resistance in the pedal when they come on. You can actually lock the rear brakes up and skid the rear tires. If you push the pedal down further the front brakes start coming on and if you push all the way to the floor the truck will nosedive and you will get planted in the windshield.
I wonder if the aftermarket Bronco Graveyard proportioner valve is blowing all the pressure to the rear wheels because it won't do it if you take the vacuum off of the vacuum booster. You have full pedal when the booster is deactivated and all the wheels operate normally with the exception of having to plant both feet on the pedal to stop it.

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.

On my way into work this morning I had one of those everybody needs to stop NOW moments. Hit the brakes hard, really hard with wheels chirping and all, after i got mostly slowed down the pedal gave way and went to the floor. I let up and pushed again and they were fine, but at that point I didn't need to hit them that hard again. The rest of the way in they worked fine braking normally, and before hand as well.
I'm thinking the master cylinder is going bad. Any tips on diagnosing for sure?

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.

1987 F-350 460 Auto Trans. Brake Pedal slowly going to the floor. Stopped at a red light yesterday on a slight down hill and I noticed the brake pedal slowly going to the floor. I had to put the truck in Park to avoid bumping into the car in front of me. I checked brake fluid level and still at the full level, check rims for brake fluid leak from brake cylinder, none. Could my master cylinder need rebuilding or is my vacuum diaphragm going. Not sure that's what its called.

Ever since I've had this truck my parking brake has acted like this. My buddy has an '03 and his acts the same, but I figured I'd ask the question.
9 times out of 10 to set the parking brake, the pedal goes almost to the floor and doesn't seem like it really does anything. The other 1 out of 10 it goes half way and feels like it actually sets. Is this normal?

I was driving, Iput the brakes on then suddenly I heard a loud bang and brake pedal went all the way to the floor. I knew there was something wrong with the brakes, parked went and checked the passenger side rear brake caliper was ripped off which made a hole through my rim and also ripped off the brake lines. I need to get the part but I don't know what its called. See the pictures....

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.

The other day I got in my truck and started down the driveway when I realized I had no brakes, I slowly backed up and parked it. I haven't driven the truck for approx. 2 weeks and it seemed fine then. The master cylinder is full, there are no signs of leakage from wheel cylinders or lines. Today I unscrewed the left front zert and no fluid came out. My pedal goes all the way to the floor.... Whats going on, and if its a easy fix?

First, I am fortunate that I was only going 25 mph when some turned in front of me causing me to slam on the brakes. The pedal went to the floor, but did slow the truck enough to miss the jerk. Had I been on the highway, it would have been very bad.
Anyway, what I found is still hard for me to believe for two reasons. It find it hard to believe it failed, but more important that I am getting the last national inventory of 2 of the 3 lines in this picture (according to my Ford dealer).
The three lines are almost directly under the front end of the master cylinder between the block and frame. These are as I found them. The larger one goes to the rear feeding both rear brakes while the two smaller run to the front brakes. The spring looking part below is just a plastic protector. The line which failed goes to the front left.
I think anyone with a 2005 SuperDuty which uses the same or similar parts should take a very close look at the flex sections. The parts I have ordered are: 6C3Z-2B523-BA, 6C3Z-2263-BA, and 6C3Z-2264-BA (rear, right, and left).
How long a manufacture is required to maintain inventory? I thought 7 years, but someone suggested 17. I'm at 8 years, but I would have expected more than 1 each of the fronts to be available. Do they changed parts on the '06 or '07?
My 350 spent 2 winters in the Chicago area and has been resting in Florida since 2006. No work was done in this area, but the closest work was the main fuel pump (frame mounted) replaced 2 years ago, but that is almost 2 feet to the rear.
