Symptoms of a bad brake booster...or is it the master cylinder?

[dandingo]

So my brakes have been bad for awhile now and it's finally time to fix them. The symptoms are that when I brake the pedal feels decent but goes to the floor.

If I pump them sometimes they're better but the pedal always goes to the floor. I've bled them on two different occasions and that didn't fix it so I believe it's the master cylinder.

My dad thinks it could be the brake booster or possibly a vacuum leak. Any help would be GREATLY appreciated!

Sounds like a bad master cylinder to me. A failed brake booster typically results in a very hard pedal form lack of boost.

Thanks man, I concur. I was 99% sure but another opinion is always appreciated.

You've got one or are you saying I should just buy a repair kit? Where can I get a repair kit from and is it worth it to rebuild it or is it a pain in the ass?

But do you have to hone out the inside??

Yes, Autozone, it's an easy fix, you can pre bleed the master before you install it.

Awesome, thanks for the info Bob. Where would I pick up the rebuild kit?
