ABS module bleed suggestions????
1998 p30 chassis, 4 wheel disc with hydraulic brake boost from the power steering pump. Replaced the master cylinder with a bench bleed. Replaced the hydraulic booster. Replaced all 4 brake calipers....

yes, when I replaced the hydraulic booster that was in the instructions to bleed the pow steer pump. No, the problem for me was air trapped in the ABS module.... just couldn't get it out...tech2 scan tool glitch won't allow it to link up. Only 2 years of chevy 97 to mid 99 won't allow link up. Funny how it showed up on the pass front caliper. Drove to town yesterday and no brake drop at stop lights no pump up and it squats when I'm braking. The "slam on the brakes" method seems to be the answer for these year of P30 chassis. get the rear wheels off the ground, 55mph and "slam on the brakes" then re-bleed all 4 wheels. But I'll bet you only get bubble out of the front right caliper!!!!!

I was having a heck of a time bleeding my brakes until I found the following note after a lot of searching brake problems.
"After bleeding the brakes on the P-30 chassis in the normal manner start engine and rotate steering wheel all the way to the stop in each direction two or three times".
Made a big difference in my brakes but they never work like a car or pick-up.
