2 brands of calipers were used ATE & you'll have to look up the other one. It doesn't matter what brand you use as long as they are a set. You have to weigh the price and quality of the rebuilt caliper against the price of rebuilding yourself. Installing new seals isn't difficult. Fast lane has the kit.
