Brake bleeding NOOOOOOOO

[Sal Lubrano]

I want to bleed everything that can be bled on my PM and wheels. I will be gravity bleeding the wheels. Which lines on the PM do I need to lossen? The two on the sides go to the front and rear brakes. Do I need to open the other line on the PM??

I dont have my brake guide anymore, but there is a special procedure for our cars. I mean it has to be followed step by step. Maybe GM can help ya, or someone else on this board who knows it better than I do.

You must bleed the system with the ignition off,so the PM motor does not run. You also must pump the PM 10-15 times to get the pedal rock hard. After that it's just like any other car RR,LR,RF,LF.

If you really want to bleed the entire system then start with the master cylinder...get a MC bleed kit...look in the HELP section in any auto parts store...it's like $5...remove as much fluid from the reservoir as possible then fill with fluid and bleed the MC...after bleeding crack each line going to the MC and gravity bleed for a few minutes...then bleed each wheel...I used to use a Mighty Vac hand pump which worked very well...I now have a Mighty Vac bleeder that works off my air compressor...much better...
