GiroDisc 14-20 BMW M2/M3/M4 (F8X w/Blue Calipers) 380mm Rear Caliper Rebuild Kit

This GiroDisc caliper rebuild kit contains the necessary components to service the rear brake calipers on your 2014-2020 BMW M2, M3, or M4 equipped with the F8X chassis and blue calipers, specifically for the 380mm rotor size. When your calipers start to feel sticky or the brake pedal doesn't feel quite right, a rebuild kit can often bring them back to proper working order, ensuring consistent braking performance.

Inside this kit, you'll find the seals and dust boots designed to replace the worn-out originals in your rear calipers. These small parts are critical for keeping brake fluid contained and preventing dirt and debris from entering the caliper bore, which can cause damage and lead to sticking pistons or leaks. Replacing these seals is a common step when performing a more thorough brake service, helping to maintain the integrity of your braking system.

Properly rebuilding your calipers can help restore smooth operation and prevent further damage. Always refer to the manufacturer's installation instructions for the correct procedure and any specific tools or fluids required for the job.
