2001 ford focus brake pedal goes all the way to the floor....y?
I have a 2001 ford focus and I just changed the front brake pads and rotors. After I was done I realized that the brake pedal was way to soft and went all the way to the floor, so I went ahead and bled both driver and passenger side brakes. It did nothing, the pedal is still way to lose, I bled the brakes for 30 min. And went through a bottle of dot 3 brake fluid! What else can I check our do to tighten it up? Please help.....
My brake pedal goes to the floor after i just had both of my rear pads, shoes and wheel cylinders replaced?
I have a 2001 Ford Focus ZX3... the mechanic at that shop claims he checked everything he possibly could, so right there I knew an idiot just worked on my car. I asked him if it could have been the Master Cyclinder or the Booster. He had no idea... Any info would be much appreciated :)
Brake pedal Goes all the way to the floor.?
Read all of this before u just yell something out.. The brake pedal Goes all the way down until it hits just a little resistance at the very very end.. perhaps a half inch of braking power.. I have replaced 1) the calipers 2) the rubber hoses 3) the master cylinder 4) the power booster I have no idea what to do next and also if u could answer.. would 1 brake line unbled lead to this problem? someone has told me even 1 unbled brake line could have the entire brake system compromised like this. I have replaced every part i can think of..
What does it mean if the brake pedal goes all the way to the floor? How do you fix it?
That is bad! It means there is a leak somewhere. It could be a bad master cylinder, a loose brake coupling, a rusted-through brake line, or a burst brake hose. I have seen all of the above. Oh, or a conked-out ABS controller.What you first do is jack the car up and use a flashlight and follow the pipes from the master cylinder to the ABS manifold and then to the wheels. If the pedal went to the floor then at least a tablespoon or more of fluid has drained out, so you should see a wet spot somewhere along the way. I’ve had brake lines rust through, master cylinder internal seals fail, and brake hoses fail. If you don’t see any leakage anywhere, look under the dash where the brake cylinder peeks through with a shaft that the brake pedal arm pushes. If you see any moisture there, then the master cylinder seals have failed.It’s also possible for the master cylinder to fail with no external signs. So if you don’t see a leak anywhere, it almost has to be the master cylinder. That’s been my experience twice, I saw no leaks, I replaced the master cylinder, and all was well again. So that diagnosis by eliminating everything else seems to work.Oh there is also a very small chance that the fluid is leaking at the caliper piston or brake shoe piston, but that’s pretty rare. If you see liquid dripping right at the wheel, then that’s probably the cause.
If the brake pedal goes to the floor and the car barely stops, is it the master cylinder or pwr brake booster
Could be low of fluid. The brakes will still work if the booster is bad. You have to push a lot harder. Brake systems are closed systems. If your fluid level is below minimum, your brakes need professional attention.
Brake pedal goes to floor only when engine running?
you said you replaced the check valve in the booster but it sounds like the booster is bad. i would change the booster and bleed all 4 wheels again.
Can the brake booster cause the brake pedal to go to the floor? Also when the engine is turned on, a hissing noise comes from the booster especially when the brake pedal is depressed and the engine idles rough?
These are 2 different symptoms of different problems.The booster has no effect on the pedal going to the floor. A pedal will go to the floor completely based on hydraulic and mechanical operations. The primary things that cause this are either a bad master cylinder, where the seals do not hold the correct hydraulic pressure when pressing the pedal, or occasionally air in the brake lines, or leaking brake fluid out of the brake hydraulic system. A third possibility exists, which is that the brake pads are extremely worn, but then you’d have other issues. It is often a combination of some of these.The hiss could be a number of things. Depending on the kind of car, there could be a number of different vacuum related components near that side of the engine bay. The brake booster is one of them, but brake boosters almost never fail these days. It can happen, but its not something common, unless of course, the master cylinder rear seal fails and the booster starts to drink brake fluid, which could cause your pedal to sink as well. EDIT: (Adding Frank May’s excellent point). Also, note, that the failure of a booster usually leads to a rock hard brake pedal, not one that sinks to the floor.Other things that could be a cause of a his and bad idle are a bad manifold vacuum line TO the brake booster. A bad evaporative system solenoid could do that as well as many manufacturers connect them to a vacuum line as a way of bleeding off gasoline fumes back into the intake manifold. Any number of other vacuum connections near the intake manifold could cause this as well, also cause an odd idle.It sounds like there’s a few things actually going on. The most critical of which is the pedal going to the floor. The booster has no affect on that in 99% of cases, so those aren’t often related.
I just replaced rear brake shoes, now my brake pedal goes all the way to the floor, what do I need to do?
I just had the shoes to my drum brakes replaced on my rear tires, 1999 Plymouth Breeze. I had pumped the brakes a couple of times with the car running afterwards and the brake pedal seemed fine. I had not driven the car since then because I needed to replace the alternator as well. Now I took my car out today and the brake pedal goes all the way to the floor. The car stops, I just need to push the pedal all the way to the floor. The guy that did my rear brakes, did not do any bleeding of the brake lines, not sure if that needed to be done. I do not see any leaking of any fluid in my driveway. Do I need to put brake fluid in, do I need to bleed the brake lines, is there air in the brake lines? I need some help on what needs done. Thanks!!
Brake pedal goes to floor even after new master cylinder...?
Brake pedal has been going to the floor barely slowing the car. Have to floor brake pedal to stop the car. Put in new master cylinder, no change. Brake lines don't appear to be damaged, one was replaced after wear but still no change. Any idea on what might be causing this? Mechanic said brakes are fine but don't know if I should trust that. I don't want the brakes to go out completely while I'm driving and make me run off the road. This is a '07 Jeep Wrangler for extra info.
Brake petal has no resistance, it goes all the way to the floor. Car will not stop.?
the mechanic needs to re-bleed the brake system. IF the car has ABS (anti lock brakes), the dealer is probably the only place that can bleed the ABS system. a scan tool has to be plugged in and actuate the ABS valves to purge the air in it. IF the ABS system was opened up, it'll need to be bled. if it wasn't, it should be fine. a brake pedal that goes to the floor is a sign of a bad master cylinder or air in brake lines. all those things that were replaced were unnecessary unless they were broken. brake boosters rarely go bad, as does master cylinders and calipers. it's possible, but something doesn't sound right. Even a NEW master cylinder can go bad! They are made by man, man is not perfect. You need to inform the mechanic that you want to see your old parts next time, and/or take them with you. and also, make him prove the parts were bad. replacing the booster & master cylinder are not standard brake replacement practices. a bad power booster will make the brake pedal go hard. so hard you could stand on it and it'd barely move. Also, it could be the connecting bar between the booster and master clyinder aren't connected properly.
