Hi all, here I go with a question on brakes. I just installed a new Brake Master Cylinder and bled out the lines (I bled the master also). Here is my problem. The rear brakes will lock up when the brake pedal is depressed but the front will not...they don't even look like they move. Here is the status on the systems: All calipers have been rebuilt with new seals and new stainless steel pistons. The front calipers had been split apart to clean then re-assembled with new inner seals (no leaks). The front brakes also have all new brake lines and the rear have some new ones. Before installing the master I turned out the nut on the rod that is connected to the booster (the rod that pushes the piston in the Master Brake when the pedal is depressed) just as instructed when I got the new master cylinder. I disconnected all the line in the front and re-checked them to make sure there were no blockages, all were clean. The system is also filled with Castrol GTLMA brake fluid (DOT 4). I've bled the brakes using my wife to press on the pedal while I opened the bleeders then release the pedal after I closed off the bleeders while I had a rubber hose in a jar of clean brake fluid. I've also tried "gravity" bleeding them and nothing seems to work. Like I said the rear work great but I can't get the front's to work at all!! This is driving me crazy!! I bled the system a dozen times following the procedure in the workshop manual to no avail, I can only get the rear ones to lock. I don't have the engine running when I am doing this (to get a vacuum to the booster) since I don't believe this is needed to bleed the brakes. If I disconnect the line going into the master cylinder that feeds the front and shoot some compressed air into it I can the front calipers to lock...this tells me that the calipers are working and not frozen...am I right? I get fluid coming out of the bleeder screw when the system is all together also. I thought that it may have been a bad master and I exchanged it (the master cylinder is from a Delorean vendor, not aftermarket). I checked the brass "T" that connects the front right brake and the left front brake to the cylinder and it's good and clear from any debris. Has anyone run into this problem or am I the only one? Any suggestions? I've repaired and bled brakes on dozens of other cars with more complex systems in them (example: ABS with differentiating valves) and I have had no problems. The Delorean is one of the few cars I have seen with the most simplest brake system and I can't get the front brakes to work! ARRGGHH. Thanks in advance, Steve 3365
