This is the only auto site I'm a member of, so asking a generic brake question for my work truck, a Chevy Suburban. "The Brake Team", which I think is a local company, replaced all brake pads, drums and rotors less than 2 years ago (20k miles ago). My survey crew drives this daily for work, and there is a lot of equipment in it, so its heavy, with lots of stops on dirt construction sites, so pads are expected to wear quicker than normal. This week, the front right brake pad is down to the metal. It appears to me that the pad fell off. Its under warranty, so I took the truck back, and they told me the caliper seized up, which destroyed the rotor and pad, plus the rear cylinder is leaking and needs replaced, with a price of $700 to fix all. Visually, the rotor looks fine, no deep grooves. My question... would a caliper seizing destroy the pad like this? The brakes worked fine until the metal on metal sound of no pad a couple days ago. I think they are attempting to take advantage of me, especially since its a work truck. They didn't realize I have some mechanical knowledge, and am part owner of the company, so price actually matters. I told them to just replace the warranty items, and I'd do the rest at home. Suddenly the price dropped to $400. Still I said no, give me new pads and rotors for free, and they did. I'm picking it up tomorrow morning, so I haven't tested the old caliper yet.
