any one know whats involved with changing an abs pump on a 91 caravan

also does anyone know if there is some sort of pressure switch hooked to it

my pump works when it wants too..when it does i have a good pedal

when it dont the pedal is extremly hard to press down

 

u know there is a life time warranty on the pump and pistion for bendix brake systems?
recall 685 call a local dealer.

 

Had two go on my 1992, the first was at 90K and the second last year at 135K, the dealer did both - free of charge!
