Re: ?? power drum brakes 92 booster 70 master

A '69 pickup master will have the deep bore in the back of the piston and a '82 booster will have a short pushrod for a shallow bore (dimple) in the back of the master piston. Those two are not compatable unless you changed the intermediate pushrod.

Our masters are the same but I don't know if the 82 and 92 masters are the same. Either way if you are not 100% on your work its best you do not proceed and have it done so you know its 100%!!!
