Description
Good brakes are safety-critical on a heavy cruiser. When factory channels discontinued the original rear caliper components for the ST7 cruiser series, we engineered a far superior aftermarket solution. This comprehensive repair kit replaces rust-prone standard mild steel parts with robust, premium UK-manufactured stainless steel versions. This completely prevents hydraulic binding and seizing issues common on older bikes exposed to damp weather, ensuring your rear brake caliper operates flawlessly for the lifetime of your motorcycle.

Finish the overhaul properly. Ensure you flush out old, moisture-contaminated fluid with fresh premium **DOT 4 or 5.1 Brake Fluid** to lock in optimal hydraulic leverage and road safety.
🔧 Install Tips
- Clean the Caliper: Scrupulously clean out the inner seal grooves within the caliper body before mounting. Use dedicated aerosol brake cleaner fluid only—never use petrol or mineral solvents.
- Lubricate Seals: Apply a light coating of fresh, clean brake fluid directly over the rubber seals during assembly to ease the stainless pistons home. Never use standard grease or lithium oil.
- Bleed Thoroughly: After tightening the banjo lines, bleed the hydraulic rear brake setup thoroughly to purge out all trapped air pockets before heading out on your test ride.
