Help!
Hey guys, I just replaced the brake master cylinder, and bled the brakes. The pedal still travels all the way to the floor. Could it be the brake booster?

The brake booster only controls the vacuum pressure.. If the booster were bad, the pedal would be rock hard.. If it still goes to the floor, there is still air in the lines.. You may have to vacuum bleed it..

You need a vacuum pump with a hose. You put the hose on the bleeder farthest from the master cylinder and pull a vacuum., then open the bleeder.. Repeat on all the other wheels, working closer and closer to the master cylinder.

Should this fix the problem? I thought that the master cylinder was bad, so i replaced it. Then, I tried bleeding the brakes, with no luck. The pedal still goes all the way down, with almost no effort.
Also, its leaking some where the tank goes into the master cylinder. I used new grommets, but how would I stop it from leaking?

Maybe you should start at the beginning.. What was the car doing that made you initially change the m/c? If you replaced it for the reason that it was going to the floor, then you probably didn't need to replace it. You probably have air in the lines or a leak somewhere in the system. If you are leaking at the base of the reservoir, then you probably have a leaking reservoir (assuming the grommets are new and in correctly. Fix the leaks first, then bleed from the farthest wheel to the front.. Best advice I have....
