I have a 70 AAR and my brakes are slightly dragging. I have installed new rubber hoses all around adjusted the shoes etc. Previous owner installed a new MC and I am not sure that the MC is releasing once the brakes are depressed. Is there an adjustable rod that engages the MC?
My brakes, all 4 will get warm, front brakes warm, left rear hot right rear hot to very hot.
Any ideas?
Thanks
ANY time you replace the master on a power system (even the rebuilt original) you need to check and or adjust the booster's pushrod to prevent low pedal operation or brake dragging, generally the Mopar system needs an air gap between the booster's pushrod and the end bore of the master's rear pushrod piston of .020 minimum, to a max of .060 for proper operation.... As mentioned you can use a set of verniers/calipers to measure the bore depth of the master and the booster's pushrod, do the math, and adjust appropriately...
You also mentioned you adjusted the rears, perhaps you "over adjusted?" recheck the rears for rotational drag on the drum/shoes, engine off, rear jacked up, in neutral... After you check/set the booster's pushrod
here's a few pics..,
