I've been trying to figure out why my right side front disc brake is applying faster then the left...or maybe it's the other way around? I have done a 73 C-body disc brake swap. Running a power brake set-up with an aluminum master cylinder from a mid 80's dodge truck/van. Front brake lines T'd straight off the rear port. And the back brakes are on a SSBC manual proportioning valve.
The rotors are new off shore units...drilled and slotted. I installed them last year and this problem seemed to show up then. I don't recall the brakes doing this with the stock rotors and pads. That is the only thing I changed...new rotors, and some semi-metallic pads that came with the rotors.
I have pulled the calipers and front brake hoses. Replaced the front brake hoses with new Dorman hoses....no change. Pulled the calipers and cleaned all mounting surfaces and put never seize in these areas. Also new pins and lubed the rubber bushings so they slide like butter. Still no change. You can physically feel the difference in drag when the car is in the air, with the front wheels off. You can spin the rotor much easier on the LH side, compared to the RH side. The left side feels "right" with just a small amount of drag....the right side is too much in my opinion. With the calipers removed the rotors both spin freely to about the same degree. It's once you re-install the brake pads, and then bleed the brakes that the drag starts.
Thoughts...opinions?
