Detailed Product Description

The PowerStop - Front OE Stock Replacement Caliper L2603 is engineered to match the original equipment specifications for Mazda Protege vehicles. Featuring a cast iron caliper casting, this part provides the necessary strength and heat dissipation required for everyday driving conditions. The floating caliper design allows the caliper to move laterally, ensuring even pressure distribution across the brake pads and reducing uneven wear. The single steel piston with a diameter of 53.90 mm delivers consistent hydraulic pressure to the brake pads, contributing to reliable stopping power.

This caliper includes the caliper slides and mounting bracket, which are essential for proper installation and alignment. The gray color finish is typical for OE replacement parts, maintaining a factory appearance. The bleeder screw thread size of M8 x 1.0 allows for standard brake fluid bleeding procedures.

Installation Notes and Tips

When installing the PowerStop L2603 caliper on a Mazda Protege, ensure the brake system is properly bled using the M8 x 1.0 bleeder screw to remove air from the hydraulic lines. Verify that the caliper slides are clean and lubricated to allow smooth movement. Since mounting hardware is not included, reuse the original bolts or source compatible hardware. Always inspect brake pads and rotors for wear and replace if necessary during caliper installation.
