Detailed Description

PowerStop L15021 is part of the Autospecialty OE Replacement Brake Calipers line, a product line focused on stock-style brake service parts. This caliper is engineered for direct replacement on compatible Toyota 4Runner and Lexus GX460 front right applications, including 2015-2024 Toyota 4Runner and 2016-2023 Lexus GX460 fitments listed below. The remanufacturing process includes pressure testing and assembly with new wear components to support smooth operation in demanding conditions. This part number, L15021, is a practical choice for drivers replacing a worn or leaking caliper on a Toyota 4Runner or Lexus GX460.

Common Issues It Can Address

• Brake fluid seepage from a worn caliper body or piston seal.
• Uneven braking caused by sticking or inconsistent piston movement.
• Corrosion or wear in the original caliper assembly.
• Reduced brake response from degraded internal seals or boots.
• Noise or drag related to worn caliper hardware interfaces.

Installation Notes and Tips

Verify fitment by year, make, model, and front right position before installation. Confirm inlet thread size and bleeder screw thread size match the vehicle brake line and service setup. Because mounting hardware and caliper slides are not included, reuse or source the required related components as needed. Bleed the brake system after installation and inspect for leaks before returning the vehicle to service.

Quality Assurance

PowerStop remanufactures the caliper and bracket assembly in its Chicago, IL facility and pressure tests each unit to verify piston operation and check for leaks. The Autospecialty OE Replacement line is built for stock-style brake service with new seals, dust boots, and stainless steel pad abutment clips assembled into the caliper.
