Pedal height is determined by rear wheel brake adjustment. If your rear drum brakes are out of adjustment the shoes or drums may be worn out. when you press on the brake pedal the cylinder is not energizing the shoes when you pump the pedal you are suppling more fluid to the cylinder and activating the shoes. So check and adjust your rear brakes

Sounds like your brakes need bled or your vaccuum booster is getting ready to go.

My break pedal goes all the way to the floor . I replaced brake rotors master cylinder, and Break booster. I had to bleed the brake and still pedal still goes to the floor


You still have air in the system.(not bled properly) If you let the Master cylinder drop down to nothing then you need to bench bleed that before bleeding the lines again.

I have a 1992 cadillac sedan deville. The ABS light is on continually and I cannot build pressure up to keep the pedal from going to the floor, though I can pump and have good brakes to stop. At the stop...


first check on every wheel make sure you see no wet . from brake cyclinders leaking. make sure brake fluid is full. when you replaced master cyc. did you bleed that before you hooked lines to it if not do that. abd bleed all brakes again. if still pedal goes down then it is the brake booster its self. hope this helps.

Have no brake pressure, pedal goes straight to floor, put on new calipers and pads and bled the lines but I am no better off.


Sounds like a bad brake booster. To test, pump up the brakes with the engine off. While holding the brake pedal down,start the car. The brake pedal should drop a couple of inches and hold. If it doesn't, replace the booster.

Brakes are out. Master looks ok. Can't find lines under engine to follow. no cheater book to ckeck with.


Master cyclinders never look OK. You have to fill em full of brake fluild ( all the way to the top) and pump the breaks lots and hard. recheck the fluild and if it went down look under the truck to see where it's coming out. If you can't find it look in the floor under the break pedal where the pedal rod goes though the floor. Fluild coming out here is a bad master cyclinder, if no leak is found put in still more fluild and pump till you find wher it's runnung out. if the fliuld stays full and the pedal goes all the way down the master is bad. Masters fail alot on older Isuzu trucks.

You need to bleed your brakes, check for air in the lines making sure that you keep the brake reservoir full. Check for leaks from your master cylinder also.

I have a 96 ford explorer xlt 4wd with ABS. When I bought it it had a broken back break line. I replaced the line blead the breaks and the breaks are spongy. I googled the issuse and found out it could be...


Check your parking brake. if it goes down to the floor or does not hold, then your back brakes needs adjusted. bad master cylinders bleed off slowly to the floor while pushing on the brake pedal. If you need assistance on adjusting let me know.

1994 Ford F 350 4X4 Diesel. Brake pedal goes to


You need to crawl under the truck and inspect each brake line for leaks. You also need to check wheel cylinders and calipers. The chances are pretty good that you will find a small leak in a line or a wheel cylinder leaking, pay close attention to the rear of the truck because that is normally where these problems occur. Hope this helps.

Brake pedal sinks 1-2 inches while holding


Sounds like your master cylinder is shot. Go to a parking lot, stop, and pump the pedal a bunch of times. Then get out and see if there is any fluid leaks by any of the wheels. That would indicate a brake line leak. My first guess, however, is your master cylinder.
