Description
A complete brake lever overhaul is absolute key for anyone looking to maintain solid stopping power and total road safety. Good anchors are far more than just a quick annual MOT check box requirement—they protect your life on every ride. The standard factory steel inserts represent a major mechanical weakness, absorbing wet weather moisture before rusting heavily inside the bores. This slow maintenance reality jams the brake pads tight against the discs, dragging your speed down and cooking your hubs. Sourcing this uprated Hyosung caliper rebuild kit introduces high-quality, custom CNC-machined stainless pistons sourced directly from our local specialist metal turner in Yorkshire. It provides an un-complicated path to turn a fragile factory setup into a bulletproof braking assembly across your latest restoration project.
This custom-assembled bundle stands out from generic online options by including far more essential hardware goodies inside the box. While generic sellers supply just basic rubber rings, our comprehensive workshop pack arrives fully loaded to restore your system completely. You receive two premium stainless pistons that will likely never need replacing again, a matching set of fluid pressure seals, a fresh stainless banjo hose bolt, a replacement bleed nipple screw, and a clean set of sliding pins. This hardware combination guarantees a completely leak-free seal, preventing lever sponge feel while restoring a totally consistent, predictable brake bite on everyday journeys.

🔧 Installation Tips
- Scrub the Internal Bores Spotless: Before you attempt to push the fresh parts into the aluminum housing, ensure the internal slider cavities are completely pristine. Trapping any hardened scale or old oxidation crust inside the track loops will instantly scratch the mirror finish on your new stainless pistons.
- Lubricate the Sealing Rings Fully: Use a clean cloth to wipe down your assembly area. We highly suggest smearing a healthy layer of quality red rubber grease directly over the rubber rings and the stainless piston bodies before assembly to guarantee a smooth, slick entry.
- Inspect Your Friction Discs: Take a look over your active brake pads and stopping discs while the calipers are unbolted on the workbench. If the metal faces show thin wear lines or uneven grooving, replace them now to ensure full stopping efficiency.
