My car has done this same thing since I converted it to front disc. I used front disc setup off of a 80's diplomat. Spindles, rotors, calipers, and a master cyl from a 90's dodge ram truck I believe. The fronts just dont turn free when its jacked up. I dont think it is hurting my E.T.'s but I could be wrong.

If it's a front drum brake master, that may be the problem. And if there is enough resistance, and they grab or one does, think of the possibilities.

Have you tried just removing the caliper completly and turning the rotor? If not, just pop it off and if you find the rotor difficult to spin, most likely you have overtighten the spindle nut and that's the source of the added drag. If the rotor spins freely w/o the caliper you may try the attached tech tip which adds a spring to move the pads away from the rotor. Here's the link found in the archive. http://www.moparts.org/Tech/Archive/brake/13.html

Yes it is converted from drum brakes... I swapped to a disc brake MC, prop valve, and new parts all around, I left nothing on the table here....
Hoses bleed freely....non kinks...
Dan
In this statement you say there seems like a small pressure... IF I read it right
Quote:
After inspections, I let off the bleeders again and it seems like it is always pushing the piston in the caliper, like a constant small pressure... The brale pedal has lots of freedom to retract...
Dan
Is that what your saying ... is there pressure there or is it in the caliper (not rolling back)
