PowerStop S6040 Disc Brake Caliper Set - Front

PowerStop Front Brake Caliper Set

PowerStop S6040 is a front disc brake caliper set built for performance-focused service on select Lexus applications. It features a red high-temperature powder-coated finish, a floating caliper design, and a 60.20 mm steel piston for direct replacement of the original front calipers.

Compatible With 2009-2015 Lexus IS250, front and 2006 Lexus GS300, front, this PowerStop brake caliper set is remanufactured in Chicago, IL and pressure tested for piston operation and leak prevention. The red finish also helps resist rust and corrosion while giving the brake assembly a clean, performance look behind stock or custom wheels.

Detailed Description

PowerStop S6040 is engineered as a direct replacement front caliper assembly for 2009-2015 Lexus IS250 and 2006 Lexus GS300 front brake applications. The cast iron floating caliper uses a steel piston and a remanufactured bracket for OE-style fitment, while the red powder-coated surface adds corrosion resistance and a clean appearance. Each caliper is pressure tested to verify piston movement and help prevent leaks before it leaves the facility.

This part number, S6040, is assembled with new internal service components including pistons, seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel brake pad abutment clips. The result is a front brake caliper replacement that addresses worn hydraulic components while maintaining factory brake geometry on Lexus IS250 and Lexus GS300 front brake systems.

What It Helps Fix

• Leaking front brake caliper seals
• Sticking or uneven caliper piston movement
• Corrosion on the caliper body or bracket
• Worn slide hardware on floating caliper setups
• Brake drag or inconsistent front brake response

Installation Notes and Tips

Verify front-side fitment by year, make, and model before installation. This caliper set is a direct replacement for the original front caliper location on the listed Lexus applications, and it should be installed with the correct brake pads, rotors, and fresh brake fluid service as needed. Bleed the hydraulic system after installation and confirm proper piston travel and pedal feel before returning the vehicle to service.

Quality Assurance

PowerStop remanufactures these calipers and brackets in its Chicago, IL facility and pressure tests each unit for piston operation and leak control. The assembly uses high-temperature EPDM dust boots and silicone lubricant for durability in demanding brake environments.
