: 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...

: 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.

This must be the TSB number that I couldn't find anymore that I talked about in my previous posts. I had the rear pads/prop. valve changed on my 99 K2500 due to intermittent pulling problems. Worked like a champ! Not a problem since.
