My 95 2500HD has always pulled to the left or right when braking, and I have replaced the front pads 4 times so far (59k miles). So this weekend I pulled the rear drums and replaced the wheel cylinders with ones from a 3500. (12.99 each at Napa). What a world of difference! The truck now stops shorter with the trailer than it ever did empty. Straight and true stops with no more drifting. And great pedal feel, pushing the brake is like Grandad's 72 Riviera.
If you are tired of weak brakes on your 3/4 ton Ram, give this easy fix a try.
