According to the factory service manual, the procedure for bleeding the brakes on my '95 Suburban is as follows: 1. Install Combo-Valve Depressing tool J39177. 2. Bleed all four wheels (pressure- or pedal-method) in sequence (RR, LR, RF, LF). 3. Remove the Combo clip, then use a Scan Tool to run 4 functional tests while applying the brake firmly. 4. Repeat steps 1 and 2. It seems many people (myself included) simply skip steps 1 & 3. But I've never been happy with the way the brakes feel in my Suburban. My '95 Cavalier's brakes feel much better - nice, progressive, firm. The truck, on the other hand, is slow to apply and the pedal is slow to return. I'd like to bleed the brakes properly. I bought a Combo Valve clip. And I have scan-tool software on the laptop that can read the fuel-injection computer, but not the ABS computer - is there one available at a homeowner-friendly price? Or is there a way of cycling the ABS without it? Or some other bleeding method that gets the air out of the ABS system?
