According to the GM shop manual, you need to have a "tool" to push the front pin "IN" when bleeding the brakes on our trucks. I have used a big C clamp to do this--but then again, I have replaced the master cylinder, the proportioning valve, the calipers, the rear wheel cylinders----the booster and still the brakes on my blazer SUCK!! Even with everything new, bleeding the brakes etc. ---my pedal goes just about to the floor before the big POS stops.
Kind of getting a little sensative on the brakes issue as this is one big PITA I am tired of dealing with. About ready to convert to a newer style system. I have paid enough money to buy 2-3 2007 systems!!
