On a side note about bleeding brakes, I recently finished a total brake job on a being-restored '79 trans Am. They used a rear disk brake set-up that was marginal from the get go along with the normal front disk brakes. I tried for three cans of fluid to get the air out of the rear system, had up in the air, a special hold-off plug to keep the safety valve centered, nothing seemed to work. I made up a 1/4" clear plastic master cylinder cover with two threaded holes for brass fittings. My plan was to attach a vacuum hose to the fittings and pull a vacuum in the master cylinder. Using my Toyota as a vacuum source with a long hose, I proceeded to apply vacuum to the cap, as soon as I got it close, I could see the fluid foam up and a couple big bubbles pop up. I didn't even need to plug the hose on, just got it close. The pedal was perfect after that. I have no idea where the air was trapped, but repeated bleeding didn't move it, it took a vacuum to pull it out. I had the master cylinder off twice for bleeding before I tried the vacuum.
