When the car is on, and your press the brake and hold it down, does it go down further?
Have you had to add more brake fluid?
If yes to these questions, you have a problem. Either a wheel cylinder or a caliper.
If no to both, your brakes are working normal.
Shoes or pads will not do anything with regards to the problem.
You might need a new power assist assembly, which is at the firewall and before the master cylinder. Also if you have a corroded or otherwise damaged or stuck caliper piston on a disc brake, this could be the culprit. Also, make certain your discs (or drums) are not worn beyond recommended dimensions.
sounds like the rear shoes need adjusted. they are made to self adjust when you back up fairly quick, and stab the brakes. If this doesn't help, they may need to be manually tightened up. it should help the petal travel.
Your booster is bad or master cylinder is leaking internally.
2003 Toyota Camry 4 cyl. automatic, NO ABS (this car doesn't have it).
Front brake pads are only a year old, rear shoes are probably over 2 years old.
It has a brand new master cyl on it and yes it was bench bled correctly by a professional and I watched him do it. (NOTE: I had pedal travel before master cyl went out on me). The shoes have plenty of material on them, and the front still looks almost new. No external leaks on the system. If I pump the brakes with the car off the pedal will get firm in 2 or 3 pumps and will not sink at all it stays. I turn the car on and the pedal travel comes back. I can get a firm pedal if I pump the brakes really fast but it comes back.
Brakes have been bled well over 10 times now and still has travel.
Question:
1) Will the shoes being really old affect this pedal travel problem?
2) Will the wheel cyl cause this problem even if there are no external leaks?
3) Is there anything I need to know that I haven't mentioned?
This is driving me crazy I want a solid pedal again.
