Vacation Week from Heck

[techmike]

I was supposed to go to DC for the SAM. Had hotel reservations, ect, ect. Day B-4 leaving my rear brakes went metal to metal. I just had 4 new tires mounted a week ago, Tireman made no mention of impending brake doom..... So, r/r pads, no big deal, but during the test drive, low power, and rt rear starts to smoke. Stuck caliper, common on Blazers.. R/R rt rear caliper, A-OK. So, being the thorough type of wrenching person, I then r/r'd the left rear caliper. Since then I have no brake pedal. No amount of bleeding has cured it. Grrrrrrrr.

Faulty rebuilt caliper?

barely crack the fitting and gravity bleed it. Keep a close eye and don't let the master cylinder run dry. Sometimes the master cylinder lines have to be cracked and bled like you are bleeding a wheel. With foot pressure on the pedal just barely crack the line fitting at the master cylinder. It sure sounds like you have some air in your system....When you replaced your pads did you collapse the piston completely? Did you take the cap off the master cylinder when doing so? Make sure the master cylinder is not overfull also.

Thanks for the help guys. Got it drivable today.... I think I have some air in the ABS module, which the book says you have to have a scan tool II to bleed. ($3495.00) Also the bleed screw in the newest caliper was bad - wouldn't pass fluid when closed, but would suck air.Back to it tomorrow.

Don't you just love frigging specialized tools that only a large shop with lots of overhead can afford.

Yeah - you also have to buy the upgrades every year from GM. I am very surprised that some young enterprising geek hasn't written some software that would interface a laptop to the OBD-II port and remove the need for said scan tool..... :confused:
