Description

Over long years of road use and riding through all seasons, the basic flexible rubber boots on your stopping units naturally perish, crack, and let in grime. This slow maintenance reality allows dirty rain water, grit, and winter road salt to creep straight inside your sliders, locking up the mounting rods and corroding your small fluid drain valves solid. Overhauling your assembly blocks with this high-grade aftermarket Hyosung caliper rubber kit is the ideal way to avoid total housing failure. It ensures your front and rear controls remain completely responsive, smooth to pull, and entirely safe when you grab the levers on local roads.

🔧 Install Tips

  • Clean Your Bores Thoroughly: Use a non-destructive spray or cleaner fluid along with a fine lint-free cloth to scoop out any old sticky grease, dry crust, or brake pad dust build-up from the internal slide tracks before popping your new rubber pieces in.
  • Use Safe Lubricant: Only smear specialized silicone-based brake assembly grease onto the metal pin shafts and inside the rubber tunnels. Never use regular petroleum grease or copper paste on moving rubber boots, as it will cause the material to bloat up and swell.
  • Purge out the Air Lines: Once you have everything buttoned back down onto your wheel frames and have re-filled your reservoirs, execute a complete line bleed until you see a fresh stream without bubbles exiting your nipples.
📧 HAVING TROUBLE POPPING THE PIN BOOTS SECURELY INTO THE HOUSING GROOVES? If your caliper is binding against the brake disc face or you aren’t sure how to hook the internal dust ring tabs into place, you can upload a crisp photo of your open piston layout on the forum to get immediate advice.
