[1979 Lola]

Strange problem. Thought maybe I could get some help.
I have a 2005 Town an Country with 3.8
I replaced rear brake pads(disc) but needed to push in the piston so I loosened the brake line just a little on each rear caliper and pushed in the piston with the brake pad in place than quickly tightened the screw. I thought no problem, WRONG pedal soft to the floor. Bled the rear brake calipers still soft, took it to local repair shop they also bled rear and front but STILL soft pedal. System has NO leaks and never any problems. Any help would be great. All my friends are stumped.

Are you bleeding your brakes from the brake lines or from the bleed screws?

I'am Bleeding from the bleeder screw

I had this same problem occur with a corvette. The only way I could get the air out of the lines was to gravity bleed the calipers. Smack the calipers with a plastic hammer while bleeding. Start with passenger rear, then driver rear, then passenger front, and last driver front. As long as your master cylinder is higher than your calipers you should be able to gravity bleed.

You might also try using a one man bleeder that pulls the fluid through the system.

Agree 100%. Had the same problem on my old 80 Chevy truck I use to have. The only way I could get a good pedal was to gravity bleed them. Just keep an eye on the fluid level. It may take 10-15 minutes per wheel to do.
