Technical Description and Features

The L3123A caliper features a cast iron construction that offers strength and heat resistance necessary for front brake applications. Its floating caliper design allows for smooth piston movement and even pad wear. The two steel pistons, each measuring 46.30 mm in diameter, provide balanced clamping force on the brake rotor. Included caliper slides and mounting bracket ensure proper alignment and secure installation. The gray finish helps protect against corrosion, extending the caliper’s service life.

Common Applications and Problem Solving

• Replacement for worn or seized front disc brake calipers on Nissan Frontier, Pathfinder, Xterra, and Suzuki Equator
• Addresses uneven brake pad wear caused by faulty caliper slides or pistons
• Resolves brake fluid leaks from damaged or corroded caliper pistons
• Improves braking response when original calipers have lost efficiency
• Restores proper brake function after caliper mounting bracket damage

Installation Notes and Tips

Ensure the brake system is fully depressurized before removing the old caliper. The L3123A caliper includes the mounting bracket and caliper slides but does not include mounting hardware, so retain or replace bolts as needed. Bleed the brake system thoroughly using the M10 x 1.0 bleeder screw to remove air and maintain optimal brake fluid pressure. Verify piston movement and caliper alignment during installation to prevent uneven pad wear.
