Product Details

PowerStop L7159 is part of the Autospecialty OE Replacement Brake Calipers line, focused on direct stock-style service for drivers who want a factory-type caliper replacement without changing the braking system layout. The caliper and bracket are remanufactured to OE replacement standards, then assembled with new internal and external service components to support consistent piston movement and sealing. The phenolic piston and floating design help maintain smooth brake application on the front right corner of the vehicle.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Sticking or seized front right caliper movement
• Brake fluid leaks at the caliper body or seals
• Uneven front brake pad wear
• Reduced braking response from worn piston components
• Noisy operation caused by worn slide hardware or boots

Installation Notes

Verify vehicle configuration before ordering: this caliper fits 2014-2016 Mazda 3 front right, 2017-2018 Mazda 3 front right Japan-built without electric parking brake, and 2016-2021 Mazda CX-3 front right. Confirm the bleeder screw orientation, piston type, and bracket style against the original caliper before installation. Transfer or replace brake pads and inspect hoses, rotors, and mounting points for wear before returning the vehicle to service.

Quality Assurance

Each PowerStop caliper is pressure tested to confirm piston operation and check for leaks. New seals, dust boots, bleeder screws, and stainless steel pad abutment clips are used during assembly, and the caliper is remanufactured in PowerStop’s Chicago, IL facility for consistent OE-style service quality.
