Want this question answered?
Failed Master Cylinder would be my guess. Replace the Master Cylinder.
Any sudden brake loss can be the cause of 1. brake line damage 2. master cylinder disfunction
A rotted brake line, a leaky front caliper, a leaky rear wheel cylinder, a leaky master cylinder,
there is a number of things that would cause your brakes to not bleed. Moisture could have gotten into the lines and rusted the inside and a rust flake may be blocking it. Another reason why is your master cylinder may not be moving. And the thing that happened to me is my brake booster went out which moves the cylinder in the master cylinder...cause me to not have any fluid movement. Pretty spendy to replace the booster....more cost in labor then parts
yes happens all the time with the 2001 winstars master cylinder under firewall on driverside
The most common cause is failure of the Master Cylinder. Leaking wheel cylinders & calibers is another cause. Of course worn brake pads or shoes can cause defective brakes. Lastly would be a broken brake line hose.
I have run into this before and it was a bad master cylinder that kept pressure on the brakes .
No, a busted brake booster will not cause the brake pedal to go to the floor. It will however cause the brake pedal to be extremely hard to push. A defective master cylinder will cause what you describe. Replace the master cylinder and bleed the brakes. It can because it happened to me. The booster lost vaccum and the pedal went to the floor. Sorry, you are wrong. The only reason the pedal went to the floor was because the master cylinder failed. The brake booster only boosts the pressure on the master cylinder and allows you to not have to push so hard on the brake pedal. Cars of yesteryear did not even have a brake booster and they stopped just fine albeit you had to push the pedal allot harder than with power brakes. A failing brake booster will not cause your pedal to go to the floor although it might cause it to go lower than normal before the brakes apply. As long as the master cylinder is good you will still have brakes, but you will have to really push hard and might even have to pump them up in order for them to stop the car.
Brakes probably need to be bled especially if you have recently had any work done to them..A bad master cylinder could also cause this.
This could be caused from the closing off of the flex line or a bad caliper or a bad master cylinder
Bad front section of the Master Cylinder or a low fluid level. Bad O-rings on piston would cause loss of both front and back.
Not usually. It is possible for the mater cylinder get suck in the apply position, but the brake pedal would not return to the up position after stopping. A more common problem for the brakes to be stuck applied is a locked wheel cylinder or brake caliper, or a jambed parking brake. These issues will be at one or more of the wheels, so check there if your brake pedal is at normal height.
