Hello all, I am at wits end with this one. I have looked around at all of the posts, and I have tried everything. I have a 1969 Chevy c-10 pickup that I just finished putting a front disc brake conversion with drop spindles onto. I completly rebuilt the front suspension, all new bushings, cross shafts, tie rod ends, ball joints etc. I have installed a brand new disc brake kit, new calipers, hoses, master cylinder, some hard lines, and an adjustable proportioning valve in the rear circuit. I cannot get the brakes to bleed for the life of me. I bench bled the MC once before i installed it, and now another time just incase. I get fluid after the factory metering block for a few pumps on the pedal, and then just air. I have filled the calipers with fluid, and I will get air and fluid out of the bleed screws for the first 2 times when following the standard bleeding procedure, and then nothing. I purchased a hand vacuum pump, and I still cannot get them to bleed.
I am thinking it is because of all of the air in the system. I had the rear differential out of the truck for 2 days, so the rear circuit bled down during that, and I had the front apart for 4 days, so it bled down at that point. So basically I am starting off with a dry system. Any recomendations? I have it sitting tonight with the bleed screws on the front calipers open to see if it will gravity bleed.
I am thinking of having it power bled at a local brake shop tommorow. Is there anything else I should try first? I worked on this for 5 hours straight yesterday and I am out of ideas. I just wanna drive the truck!!!! :smash: Thanks!!
