The stock servo had failed. I bled the brakes on the weekend and tried it out last night in the driveway. The brake pedal feels solid, doesn't have a lot of travel, but there is very little braking pressure being applied. At say 5mph the braking distance was about 10-15 feet. Kind of a gentle, pulling up motion rather than anything resembling a brake being applied. I did notice a few times that with my foot hard on the pedal it would kind of rest, then had a tiny bit more give after that. I'd read that fully depressing the brake pedal can damage the master cylinder by causing it to travel further than it should. And there were a number of times I had the pedal to the floor before I installed the new servo. So something's not right. Any ideas, could this be damaged cylinder related?
