Product Details and Specifications

It includes two steel pistons, each with a 35 mm (1 inch) outside diameter, designed to provide consistent braking force. The caliper comes with a bleeder screw (M8-1.25 x 35.3 mm) for proper brake fluid bleeding and dust boots to protect internal components from contaminants. The inlet fitting is a plug type with an M10-1.0 thread size. Note that anti-squeal shims, brackets, and caliper slides are not included.

• Addresses brake fluid leaks due to damaged bleeder screws or seals
• Restores proper piston movement and brake pad engagement
• Eliminates uneven brake pad wear caused by caliper malfunction
• Prevents corrosion-related failures with rust preventative finish

Installation Notes and Tips

Ensure the brake system is properly bled using the included bleeder screw to remove air and maintain braking performance. Verify thread sizes (M8-1.25 for bleeder screw, M10-1.0 for inlet port) match your vehicle’s specifications. Although the caliper includes brake pad installation hardware, pads themselves are not included and should be sourced separately. Inspect dust boots during installation to confirm they are seated correctly to prevent contamination.
