Help folks,
-Just completed a master cylinder swap, and then bleed on the system. I used a pressure bleeder/and second person stomping on the brake pedal process, for each caliper. -after doing this, and with the pressure bleeder still set up, the pedal felt very firm, but as soon as I disconnected the bleeder, the pedal sinks to to floor....if I pump the brake a few times, pressure returns, but then after letting off the pedal for a few seconds, it falls to the floor again..... -what's wrong!! -I am not getting any leaks, and the system holds pressure under the pressure bleeder -Adam |
