PowerStop L15020 Disc Brake Caliper - Front Left

OE Replacement Caliper Overview

PowerStop L15020 is a front left disc brake caliper built as an OE-style stock replacement for select Toyota 4Runner and Lexus GX460 applications. It bolts directly in place of the original caliper and is remanufactured for a direct-fit brake service solution.

Key Features

• Fixed caliper design with a 4-piston layout for consistent brake force.
• Cast iron caliper body with steel pistons for durable hydraulic operation.
• 100% pressure tested to verify piston function and help prevent leaks.
• Assembled with new seals, dust boots, bleeder screws, and stainless steel brake pad abutment clips.
• High-temperature EPDM dust boots and silicone lubricant support smoother movement in demanding conditions.
• Inlet thread size: M10 x 1.0; bleeder screw thread size: M7 x 1.0.

Detailed Description

PowerStop L15020 is part of the Autospecialty OE Replacement Brake Calipers line, focused on direct-fit stock replacement service. This caliper is remanufactured in Chicago, Illinois and built to restore proper hydraulic braking function with a fixed design, 48.00 mm pistons, and a gray finish. It is a practical choice for brake repair on a Toyota 4Runner or Lexus GX460 when the original caliper needs replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Leaking caliper seals or fluid loss at the brake corner.
• Sticky or uneven piston movement that affects braking response.
• Corrosion or wear in the original caliper housing.
• Brake drag caused by aging internal components.
• Reduced braking consistency from a worn OE caliper.

Quality Assurance

PowerStop pressure tests each caliper to verify piston operation and check for leaks before release. The Autospecialty OE Replacement line uses remanufactured components and new internal service parts to support consistent brake performance.
