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.

🔧 Installation Tips

  • Cleanliness is Key: Ensure the caliper bores are spotless before inserting the new stainless pistons to avoid scratching the mirror finish.
  • 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.
