so I put my new calipers on today after having them off the car for a month. I just had rubber gloves over the lines. The master cylinder was empty. I bleed the brake RR-LF-LR-RF. I then took the car for drive to go break in the new brake pads. My warning lights were on the whole time. So I come back home and bleed again this time with ignition on car off. I got a couple bubbles out of front brakes. I then bleed them again with the car running. I got a little more from front brakes. My warning lights are still on. I put 50oz through the system. I did this the old fashion way with a helper. I’m really getting irritated with this car. I also noticed my thermostat housing is leaking. I installed a new thermostat not to long ago.

Check the sensors, make sure they are all plugged in and not damaged.

Most likely a sensor.. I accidentally pulled a wire out of one of the front ABS sensors. Make sure everything is plugged in right.

Jayfabs

I’ll check them again. There was one I removed .I reinstalled though. So maybe something I missed

I suggest getting some spray contact cleaner and spraying the connection before reconnecting.

should use a Tech 2 or at least a pressure bleeder ?????

I thought there was a certain procedure needed to properly bleed the brakes. Not sure that would cause the ABS light to illuminate, tho.

Pounder

it's hard to get the air out of the EBCM !!!!!

jayyyw

If I ever have to replace ABS unit, I'd much rather delete the whole thing.

Jayfabs

Ok the connector that I thought I had properly put back was not in all the way. Problem fixed.

I love it when the fix is easy!

Don't these cars have inner and outer pistons? If so the sequence is RR outer, RR inner, LR outer, LR inner, RF outer RF inner, LF outer, LF inner. You probably have air in the system.

Jayfabs

bleed the inner first then outer then inner then outer every time I did each brake. As of right now everything seems good. I do plan on doing stainless lines. Not sure why I didn’t this time smh

Several forum members have had problems installing SS lines. GM over tightens the flair nut hard lines and that distorts the threads. which then result in the lines weeping. I had two of the lines not completely seal using the normal amount of force to tighten. When I used much more force to tighten than I ever have on brake lines they stayed tight and weep free. When I replaced my front calipers with Wilwood calipers I had to change out the SS lines and had no issues that 2nd time.

If you really don't need the SS lines you may save yourself some foul language for when you really need it. If you do change them out, one trick to minimize fluid loss and potential air in the ECBM is to block the brake pedal to the floor and plug the hard line (oversized tooth pick or similar wood skewer) until you are ready to connect the new line.

I have always bled the furthest away first so RR outer, RR inner etc with no problems.

If it ain't broke.....work on it till it is.

Jayfabs

omg that’s awesome I hate it when I have that problem.
