Brake Saga Part III .... Update 200 1985

posted by  someone claiming to be DeWayne on  Fri Apr 26 00:45 CST 2002 [RELATED]

Over the last two weeks in my spare time I installed the new brake lines and replaced the front calipers with ones that I ordered from FCP/Groton. The drivers side caliper did not fit correctly due to some raised lettering on the inner caliper housing which prevented the caliper from lining up properly. FCP/Groton promptly sent out another one without the raised lettering and it bolted up fine. I also replaced the distribution block with a new one from FCP/Groton.

Last night I made the final brake line connections to the master cylinder and pressure bled the system. With the engine off, the pedal feels real good and stops about 1/2 - 3/4 down. But when I start the engine, the pedal goes way farther down with the vacuum boost, not quite touching the floor. I pressure bled almost two quarts of fluid through the system so far and I'll bleed it again this weekend to see if that improves the pedal height with the engine running.

Anyone have a clue why the pedal drops so far down with the engine running compared to the engine being off? I would expect an inch or two but it's dropping more like six inches when the vacuum booster kicks in.

The old brake lines were shot and I got more pedal now than I had before, but I expected to get a higher pedal after replacing practically all the parts in the system. As always, any suggestions or advise would be appreciated.

Thanks in advance...

DeWayne
