Bring firm, dependable stopping power back to your Mazda Miata with the PowerStop Autospecialty Disc Brake Caliper L1378. This Autospecialty by PowerStop replacement caliper bolts on directly in place of the original stock rear left caliper on the 1990-1993 Mazda Miata — no modifications necessary. The caliper houses the piston that presses the brake pads against the rotor when you apply the brakes, so a leaking, seized, or corroded original is a common reason for uneven braking, fluid loss, or a dragging wheel.
Autospecialty by PowerStop calipers are sold individually and engineered to meet high quality standards, delivering a hassle-free replacement for the value-minded driver.
