Our take on the Detroit Axle - Rear Left Brake Caliper

A single remanufactured-style rear left brake caliper with an integrated bracket, built for a long list of GM W-body cars and the 2000-2010 Chevrolet Impala. It uses a 38 mm steel piston and comes with the mounting bracket, so it is a direct bolt-on replacement for a seized or leaking original caliper. Detroit Axle sells it as a budget-friendly alternative to dealer parts, and owners of these aging GM cars tend to like the fit and the price against name-brand remanufactured calipers. The trade-off is that it is one corner only, so a matching right-side caliper is a separate purchase.
