Tonight I got into the project of re-doing all of my break components except for the calipers. I took the cap off of the BMC, then I moved on to remove the calipers, pads, and rotors from the car. I let every bit of the break fluid drain out from all of the break lines connected to the back of the calipers. I painted my calipers, put cross-drilled rotors on, then put my calipers and pads back on the car and hooked them back up. I reset the calipers off the car right before I painted them. I then proceeded to bleed the lines in the proper manner beggining from passenger rear, driver rear, passenger front, driver front, and then did the Master cylinder a couple of times. I swear I did this to each side about 6 times and then went back through and did it 3 more times all around the car. I still have anywhere near the tension I should on the break pedal! What am I doing wrong. I have one friend making sure the BMC isn't ever empty, I have someone pump the break and hold it down, then I bleed from the caliper, close the bleeder than tell them to let off and pump somemore. What is going on? Will the air work itself out overnight. should I push the calipers all the way out and then reset them while they are on the car? What am I doing wrong? Please help! And by the way, I don't have ABS

it will take a bunch of bleeding to get all the air out. You could try loading up the system and holding the brake pedal down overnight with a 2x4 or something. That may help but sometimes it just takes a lot of bleeding to get all the air out.

Are you using a bleeding tube hooked up to the bleeder valve and submerging the tube in a open container of brake fluid about 2 inches full?

and dont press the brake if you remove the calipers, it will pop the piston out.

bleed in this order: driver rear, pasanger rear, pasanger front, driver front, ABS (if aplicable)
