I have a 52Chevy 3/4 ton and about 2 summers ago I put in a new master cylinder and had new wheel cylinders and shoes put in and the drums turned. Since then, I think I've put about 2,000 miles on the beast and now the brakes squeal when stopping right before coming to a stop. Is it an adjustment or are my shoes shot already? I find it hard to believe that the shoes would be toast.
Any advice would be great.
