2004 Trailblazer bleeding brakes

[rdnoel86]

Ok, so my wife is like Jill Taylor from Home Improvent. She calls me from the store and says here car is making some noise. I tell her to bring it home and I'll ckeck it out. Nope, no can do, has to go to her mothers to visit. Calls me from her mothers, says there is a clunking noise now and fluid all over the rear tire. Great, I'll come look at it. The brake pad is disintegrated, the caliper piston is actually out of the caliper and jammed into the rotor that is missing chunks......good grief. Ok, so I get the pleasure of changing out the rotor/caliper/pads in the rain at my mother in laws house today. Add that AZ gave me the wrong caliper and pads made for a nice day.
Got it all together and went to bleed the brakes and couldn't get only a drip out of the line. Is there a check valve or something that I need to deal with?? I googled it and found others with the same issue, but no decent responses. Any ideas?? Master is full and the pedal pressures up so to speak....but no fluid....

Did you check to ensure the brake line is not pinched anywhere? Check to see if you can bleed the opposite rear wheel, if so you know the rubber "splitter" coming off the rear end is not internally collapsed. How low did the fluid in the master get? If it is empty you'll need to rebleed that, and sometimes bleed the abs modulator. You'll need a Tech 2 or other scanner to bleed the abs modulator. The Tech 2 I use tells the computer and it cycles all the solenoids and valves to bleed it forcing the air to the brake line. You never actually open the system when bleeding the abs modulator until you get to a wheel.

Ok, I officially hate new technoligy.... I did remove the line from the caliper to make sure it wasn't pinched. Thanks for the starting points. I will try the other side first. I don't think the master went dry, but it did take a lot to fill.....so it could have.....I couldn't really see in it that well. I don't have a scanner. That sucks.....I may have to take it to a shop anyway. I'll follow your suggestions and see how far I get and hopefully get it done....Thanx!!

Here is one thing you can do. Open the bleeder on that side and have someone stomp the pedal nad hold it on the floor until you get the bleeder closed. Do this once or twice, then bleed like normal. You might have to bleed it a few times, but usually works. As for bleeding the ABS....I take the vehicle for a drive and activate the ABS on a loose surface and this bleeds the system in most cases.
If it doesn't work, your back at square one.
