Sounds like a master cylinder failure. Were you able to pump the brakes and build up pressure? If so, it sounds like an internal leak in the master cylinder, perhaps in the diaphragm inside. If that diaphragm allows fluid past it (through a pinhole, say), pushing the pedal will allow the plunger inside the MC to push straight in without actually moving the fluid through the lines, out to the brakes.

Break pedal goes straight to the floor. ABS & Break light is on


the problem is in the brake master cylinder or brake system you have a problem , probably in a leaking line or cylinder and there is probably no oil in the reservoir at all
The abs light has been telling you for a year that you have a brake problem but you happily ignored that signal and put yourself and others at risk
You will be incapable of fixing this fault yourself so take it to an accredited brake shop specialist and have the job done properly

Brakes not working


The front portion of the reservoir has fluid used for the front brakes which provide the majority of the vehicles stopping power. There is a valve that is supposed to shift to isolate the front and rear brakes when this occurs but it doesn't always work as designed. You have lost all the fluid in the front brake system. This is due one of these possible issues:

Broken brake line
Broken brake hose from line to caliper
Leaking caliper seal

You need to find and repair the leak, refill and bleed the front brake system to get the vehicle back in service. IT IS NOT SAFE TO DRIVE IN ITS CURRENT STATE!!!

Leaking brake fluid from right front wheel 1995 honda passport


Sounds like from what you describe it's a leaking break caliper. The best thing to do is get a rebuilt one. It's best to replace them in pairs. Also replace or clean the brake pads thoroughly!

My right wheel isn't spinning when I'm driving and it's making this horrible squeaking/howling sound. What's wrong with it?


Hi,
WHAT wheel(S) are not spinning? Front/Back/Left/Right?

Do you use your parking brake? If so, it may be stuck "ON" even when you release it.

Take it back to the mechanic and have them do a complete brake test. You're probably due for a brake job - brake pads and/or shoes, new rotors and/or drums.

First, there is NO Pumping of the brake pedal

need to replace both rear brake hoses,
before you proceed with the bleeding

Brake problems


by repressurize, do you mean 'pumps up'. If everytime you hit the brakes (allowed to sit for a few moments between uses) it starts applying the brakes near the 'normal' pedal position, then it sounds like the master cylinder has gone bad.

Other less likely causes, lots of water got in the brake fluid (assuming nonsynthetic brake fluid) and has turned to junk.... Might try power bleeding the system, but my bet is the master cylinder.

Peace,

While driving my 1994 Honda Accord the brakes went out. I can only get the car to stop if I press the brake pedal all the way down to the floor. When the car is shut off and I pump the brake pedal, I can...


There may be air in the lines. Bleed all your brakes starting at the farthest wheel from the resevoir, and finishing at the closest one. Try the pedal after its bled. If the pedal still feels soft or travels to the floor there may be a pinhole leak that may be spraying on the underbody of the car, or the seals in the master cylinder are gone filling the vacuum booster(if equipped). Air compresses more than oil so if bleeding works that may be the problem.

1998 bravada brake problem


If you have not replaced any brake lines or brake calipers, then It sounds like that the brake proportioning valve or the brake master cylinder if defective. If the the brake pedal goes to the floor, the master cylinder is at fault. If not, the proportion valve, which is part of the ABS valve body is defective. Have your local garage check these two components for possible problems.

Soft brake pedal after rotor replacement


If they rebled the brakes and the pedal goes to the floor, chances are that the master cylinder is bad. Probably cost about $80-100 for the part if you could do it yourself
