With 38K on my K1500, pads were getting real close to the wear indicators. Changed them last weekend to kevlar/carbon composite pads from Praise Dyno Brake in Royse City, TX. Cost was around $90 delivered. Made a BIG difference in stopping distance.
Also found an interesting GM TSB while surfing through the All-Data CD-ROM at a good friend's shop. This is the substance of the TSB...
Subject: Brake Lead/Pull and Front Brake Wear
Bulletin No.: 86-50-20
Date: April, 1998
Subject: Brake Lead/Pull and Front Brake Wear (Replace Rear Brake Shoes)
Models: 1992-98 Chevrolet and GMC C/K Truck and Suburban Models
1996-98 Chevrolet and GMC G Vans with RPOs JB8 or JD7
Condition: Some owners may comment about the vehicle leading or pulling to either side while applying the brakes or front brake wear not meeting expetations, especially vehicles that have been used to tow a heavy load.
Cause: Conditions may be caused by excessive wearing of the font brake material. Improvements to the above conditions can be gained through rear brake material modifications. On Suburban models, the best performance from this new brake material can be achieved with replacing the proportioning valve.
Correction: Replace the rear brake shoes with Dura Stop brake shoe kit. On Suburban models (C/K 20906), a proportioning valve must be installed. All other models (C/K, G), no proportioning valve change is required. Use the part numbers listed. Refer to Section 5C2 of the Service Manual.

That's the end of the service bulletin. Please print it out, as I don't especially want to retype the sucker.
Has anyone ever had the work done???
