A disc brake caliper that leaks, sticks or wears one pad faster than the other can pull the car to one side. Before you replace it, rule out worn pads, a damaged brake hose or a seized slide as the cause. Replace both rear calipers together when you can; this listing is one rear left caliper, and the rear right is a separate part.
