Description

A brake caliper rebuild kit is essential for all Hyosung owners. Good brakes aren’t just an MOT thing—they are critical for safety. The factory steel pistons are a known failure point that rust internally and cause your calipers to seize. We solve this by supplying a complete bundle of genuine seals and high-quality, custom-made **Stainless Steel Pistons** from our local brake piston maker. This is a repair or full restoration kit for ONE CALIPER.

💎 Performance with the Reliability!

Yes, that’s right—proper stainless pistons you’ll likely never have to change again! This kit turns a weak point into a bulletproof braking system that provides consistent performance for the life of the bike.

Yorkshire Made Custom CNC Stainless Pistons.	Zero Corrosion Guaranteed rust-proof pistons.

Lube Everything: Use a high-quality red rubber grease on all seals and the new pistons for smooth operation and longevity.
Pro Tips: Always inspect the brake pads and discs when rebuilding calipers. If you need a guide, check the HyoRiders Forums for detailed tutorials.
