brake bleeding sequence
I have recently replaced all calipers and pads. Still have soft pedal. Have installed speedbleeders and bled brakes 3-4 times. Pedal still soft with engine running. Is the proper bleeding sequence Right Rear, Left rear, right front, left front,or as Hayes has published Lr,Rr,Lf.Rf? Any other insight is appreciated.

etc. You may need to bleed the master cylinder also.

i have never had luck doing it only once after a full rebuild, on the British cars i did you almost had to let them sit overnight so all the bubbles could get together.....i just bled my brakes (annual maint) using the pressure bleeder and took out about 7oz of fluid from each caliper.

Takes longer to take the wheels off and put on that it takes to bleed them!!

Mikewho,
When bleeding the rear brake system the front of the cab should be raised higher then the rear, this will position the bleeder valve near the 12 o'clock position and prevent air from being trapped in the caliper.
