4 wheel disc, mine suck!
Just finished a 4 wheel disc conversion. Here is a list of everything in the braking system that has been replaced so far, but they still suck.
-New Rear disc conversion from SSBC
-almost all new brake lines
- new, not rebuilt, 80' corvette master cylinder for 4 wheel disc
-new front calipers, rotors, pads
So basicaly everyting is new. I have bled and bled these things and they still suck. I bench bled the new master cylinder, gravity bled all the brakes, bled the brakes after pumping pedal 3 times and holding ect. last time I bled them I started at the rear furthest from the MC and worked my way up. After I bled the rears I had a very firm pedal. As soon as I started bleeding the fronts the pedal got softer and softer. They are so bad that in low range they will hardly hold the jeep on a hill. I dont think there is still air in the lines because consecutive pumps of the brake pedal do not make it firmer. My next area to look at is the proportioning valve on the drivers side frame rail. I dont know much about it, but it seems like the only thing left to look at. Please help, I want to drive the jeep more before snow starts falling, but at this pace I doubt I will. any suggestions/ replys are greatly appreciated. [img]images/graemlins/smile.gif[/img]
