OFF TOPIC (GMC TRUCK BRAKES)

NW Florida, huh? Has your Jimmy been to the beach and dipped a toe into the water recently? Seriously.

When the Rice-Eating Generic Chevy Truck was about 3 years old, she hauled a bunch of stuff and some of the kids in my Boy Scout Troop on a weekend trip to Fiesta Island in Sandy Eggo. At the time, San Diego County was not quite as left-leaning as the rest of the state; and we could pull out on the beach to load and unload gear. That Sunday morning (we were leaving early), I rolled the left-front tire/wheel through a small tidal puddle. Later in the morning, same story as yours - first stop was okay, but it would pull to the left. Next application of the brakes found me diving for the median on Interstate 8

Pulled it all apart - one b***h of a time getting the caliper bolts loose; and a coating of white crusty stuff all over the bolts. The caliper was "hanging up" and wouldn't slide enough to relieve pressure on the inboard brake pad - it was always trying to brake, so it grabbed really quick with the slightest pedal pressure. Hosed the bolts and the caliper mounting ears with spray-on Liquid Wrench, WD40 and Brake Clean, dried 'em off and shot 'em down with spray silicone. Worked great for about two weeks, and same thing all over again. I finally gave up and replaced the bolts. I guess it was something about the saltwater residue getting baked into the light plating on the bolts and the cast iron of the calipers.

There's probably a simple fix for the problem; but I thought new bolts were a pretty simple and cheap fix, considering the circumstances.

I would say its the front rubber hoses or the slide pins. Remember that the front hoses rott from the inside and may look fine from the outside. I would replace those two items first and if it still acts up I would look at getting new calipers. Remember to always to replace brake componets in pairs.

I had the same problem with a GM product (front left).
I tried the WD40 thing as well, and it worked for a short time. I ended up replacing the caliper and never had the problem again.

- Could be a caliper problem.
- Doubt it's the brake lines unless 1 side got kinked.
- Could also be some worn out ball joints.
