have an (new to me w/29k mi.) '02 Liberty on which the front brakes rotors seem VERY hot after long term run. The calipers are seemingly not unloading correctly.
Questions: ? Whats the best way to remove the friction in the disc brake system so that these can unload properly? .... removing the dust covers and applying a proper caliper grease? .... lubricating the piston seals? etc. ? Can the old caliper piston dust covers be reinstalled or does one normally destroy them when removing? ? What would the correct amount of piston 'preload' be so that there is 'enough' residual piston pressure to hold the brake pad 'close enough' to the rotor but NOT cause significant drag ..... dont want to get into brake vacuum booster preload - yet.
Advice appreciated. Thanks for your reply.
