Brake booster trouble, or is it?
I recently rebuilt my clutch master cylinder, and in the process I decided to rebuild my brake master cylinder as well. I pulled both the master and booster to get to the clutch master. Today I got the brake master rebuilt, and the whole system rebleed with fresh fluid, and I have a very hard pedal. I go for a test drive and the brakes stop real good, but almost to good. I get about 2 miles away and they feel like they are draging. Going down a hill I put it in neutral and cost only to find they are dragging and very hard. I pull over to let them cool a minute while I look under the hood for anything suspicious. I get back in to leave and the car won't move. I killed it 3 times trying to leave and I even reved it up to about 5K let out real quick. The car moved about 5 inches and died. I fired it back up and decided to unplug the vac booster. As soon as it lost vacuum the car started to roll backwards. I forgot to pull the e-brake and I had to jump in real quick before it rolled out into traffic! After getting it home without a vacuum booster I got out the factory service manual and did all the checks to determine if the booster is bad or not. Well all three checks turned out OK...WTF? My pedal is still hard as a rock, but when I try and move the car with the booster hooked up it won't roll?
So is this a booster problem? Do I not have the pedal adjusted properly? Is my freshly rebuilt master cylinder to blame?
