Get firm, reliable rear braking back with the PowerStop brake caliper L1378, an Autospecialty by PowerStop direct-replacement unit that bolts on in place of the original stock caliper. It's the rear left caliper for the 1990-1993 Mazda Miata, installing with no modifications necessary.
Each caliper is sold individually and expertly assembled to deliver a hassle-free replacement:
The caliper clamps the brake pads against the rotor to slow the wheel; worn or seized calipers can cause uneven pad wear, brake drag, pulling, or a soft pedal. This L1378 replaces the rear left unit on your NA Miata. Since this listing is for one caliper, it's best practice to replace the caliper on the opposite side as a matched pair for even, balanced braking. See the Buyer's Guide tab for full application details.
What vehicle does the PowerStop L1378 brake caliper fit?
It's a direct-fit replacement for the 1990-1993 Mazda Miata. Check the Buyer's Guide tab to confirm it matches your specific vehicle before ordering.
Is this a front or rear caliper?
The L1378 is cataloged as the rear left caliper. It bolts on directly in place of the original stock caliper with no modifications necessary.
What comes with this Miata rear caliper?
It's assembled with new seals, caliper guide pins, dust boots, bleeder screws, stainless-steel brake pad attachment hardware and a mounting bracket, and is 100% pressure tested.
Do I need to buy two Miata calipers?
This listing is for one caliper, sold individually. Replacing the caliper on the opposite side as a matched pair is recommended for even, balanced braking.
What are signs my brake caliper may need replacing?
