The RABS module consists of a spring loaded dump chamber and two solenoid operated valves. They can go bad but no point in replacing one just for the heck of it.

could it cause your back brakes to be slow to release if it was bad

If this is a problem your having I'd suspect the rubber brake hose first. The inner lining can split and act as a checkvalve not allowing the fluid to release back.

I agree with 87. the rubber brake hose is a good suspect. But to answer your question, yes it is possible.

i ve changed everything the back rubber brake hose, the back steel lines, new master, new booster, new wheel clyinders. but i ve never changed the abs module. sometimes it does seem like the back brakes are slow to release, like after a hard quick stop.

Are you feeling a bit of a drag, then a "clunk" release of the rear brake?

Does it make any difference between forward or reverse?
