Hi, Just installed 4 new calipers. 4 new rotors all pads and master cylinder..
Flushed all the brake fluid with Dot 3
Bled master cylinder and all calipers.with a manual power bleeder.
Problem is in the morning when I leave for work brake pedal is perfect...But after driving a bit pedal gets mushy.
I now have rebled the master and calipers 4 more times since but still the same.
I've been working on cars for years so I know the proper way of doing this brake job but I'm stumped..
Just looking for some ideas.
Thanks in advance.

1999 catera. Excellent condition..87000 origi

Hello! I see this is from two months ago and maybe you solved this problem already, but here is something for you anyway. I have a '97 shop manual and scanned the relevant pages, hope it helps. If you did fix it please post what you did for future reference.

Thanx for the pages but I have the same 97 manual..I talked to a mechanic for a second opinion and he said as long as everything was done correctly (which it was)..the only other thing could be the abs...I just ordered a scan tool to see if it is the abs..

while pedal is mushy, do you still have that brake grad or its faded?
