After searching all of the forums and having read about the TSB 99-05-24-001, which covers the need to replace proportioning valves and rear brakes on certain model, I felt I had found my answer... My K1500 4x4 suburban SLT is chewing up brakes like candy- just the fron ones, and more of the inboard pad than the outboards. The rear shoes don't seem to contribute to a STOP, as the nose seems to be pulling downward. I assumed that the fix was to replace the Prop. Valve and switch to the shoes mentioned in the TSB. It specifically says: "Replace the rear brake shoes with P/N 18029651. This does not apply to the 13x2 1/2" brake shoe, the Dura Stop P/N 18029650 brake shoe or any other size brake." Since the vehicle only came with 11-5/32 x 2-3/4" or 13x2 1/2" brake shoes, I stupidly assumed that the fix indeed applied to me as I do not have 13x2 1/2" brake shoes; but the smaller 11's. The new shoes I ordered are 13's!... like I said "stupidly assumed". So now I have a new proportioning valve and I need to put the shoes back in as the new ones dont fit the spindle plate or drums. What type of shoes (11's) can I go to for the best stopping power? In bleeding the brakes- new wheel cylinder needed, I plan on pressure bleeding- does the dirt road ABS activation prior to bleeding trick work?
