Technical Details and Features

This disc brake caliper features a single steel piston with a diameter of 47.85 mm, designed to deliver consistent hydraulic pressure to the brake pads. The floating caliper design allows for self-alignment during braking, reducing uneven pad wear. Constructed from cast iron, the caliper offers durability and resistance to heat and corrosion. The gray finish further protects the caliper from environmental factors. Note that mounting hardware and caliper slides are not included with this part.

Installation Notes and Tips

Ensure the brake system is properly bled after installation to remove air from the hydraulic lines. Since mounting hardware and caliper slides are not included, reuse existing components if they are in good condition or purchase replacements separately. Verify compatibility with your specific vehicle model and year before installation. Use the bleeder screw with a 3/8 x 24 thread size for standard brake bleeding procedures.
