RS out of 9 yr Storage....Front Brake Issue
 

After nine years I've taken my 91 RS out of storage. One of the first things I noticed was that the passenger side front caliper was frozen. I got the caliper off and could not push the piston back into the caliper. So replace both front calipers with a pair of Power Stop calipers. The car then began pulling to the right when the brakes were applied and the pedal was soft and sometimes even going to the floor. The next step I too was to replace both front rotors with a new set of cross drilled and slotted Power Stop rotors as well as bleeding the brakes. Bleeding the brakes is where the problem comes in. My son I were bleeding the brakes but could not get any fluid nor air out of the driver's side front line. When we moved to the passenger side front that caliper was once again frozen to the old rotor. We had to disconnect the brake line to remove the pressure from the caliper and remove. We still could not manager to bleed any fluid or air from either caliper. Any ideas to the potential issue? I am leaning towards some sort of blockage and possibly replacing both rubber brake lines on the front. Any thoughts or ideas?

Replace all of the rubber lines. Even the one from body to rearend.

I agree with changing all the rubber lines. My problem was my bleeder screws were packed with crud. Had to take them out and clean them.

Man, I didn't want to finish reading the op, just skipped to the replies... Good call.

Flush the fluid while you're at it. Turkey baster most of the old black fluid out of the reservoir, fill with fresh clean Dot 3, bleed furthest corner until clean fluid with no bubbles. Repeat all four corners until all are bled, fluid is clean. It's a maintenance item, look it up for reference, I want to say its something like every three years. Most people don't bother, but the fluid absorbs water, eventually it cant hold any more water, and you get rust in the hose fittings and things start to lock up.

I replaced both of the front rubber brake lines and the seems to have solve the issue. Getting the brakes to bled to ensure all is working properly. Thanks for the input!
