Okay I am taking the Explorer over to a buddies monday morning and we are going to check out the whole rear end to make sure that my dragging drivers side rear brake is really the brake dragging. Make sense??? Well I have replaced the caliper, rotor, pads and it still is dragging. In my conversations last night I found out that since this thing has ABS it may not have been bleed properly at one time. My parents used to own this thing and had the rear axle replaced by a Ford dealer last year due to some weird deal in the axle... Well my buddy was thinking when they did this they didn't blead it correctly. He thinks that they may have left some air in the system. Okay with all that BS said, is there a way to FIX the ABS proportioning valve without having to replace it??? My buddy was saying he didn't have the tools to do this but wanted to look at it with me anyway just so I know what's going on. THANKS!
