I have a 1990 Honda Accord LX. I am having problems with the brakes. When I apply the brake pedal it feels extremely spongy and needs to be pumped and eventually depressed clear to the floor for the car to stop. I have bled the system at all 4 tires, the master cylinder fluid level is full and there are no obvious leaks to be found. The car does stop, but the amount of effort required makes me worry about being in any traffic and/or having to make a quick stop. Am I looking at a master cylinder or power brake booster problem, or both?

Any assistance would be greatly appriciated.

thanks.

 

A wiped brake booster would make it feel hard to the touch (the pedal)

Take your rear wheels off and have a look. Betcha you have a wiped out wheel cylinder (if drum equipped). If so, replace them both with new hardware and shoes.

Another possibility is you have air in the lines from bleeding the system. You must have a steady stream of fluid coming out of each bleeder for it to be considered bled.

 

These cars also have a proportioning valve that can "bleed by"..No loss of fluid, but serious loss of pedal..
