asilverblazer You better give that booster a chance,both of them,thay like a dose {2 oz.) of hydraulic jack oil to lube a big leather cup in there. The big truck service book tells how to do this,my two are 71 yrs. old work good !! Always big fun to climb on the brakes and know you can stop !! they worry about disc brakes all the time, my 51 6400 made into a 98 inch wheelbase pickup has plenty of brakes. It is pretty happy at 50 MPH on good roads has 8.25x 20 with 4 and 2 speed axle.
