Rebuilding the Rear Brakes on the Legendary Unicorn JAPAN “Oil-Cooled Katana”
GSX1200S! Vehicle: GSX1200S Oil-Cooled Katana (Built by Unicorn JAPAN). Topic: Comprehensive overhaul of the rear brake caliper and master cylinder. Details: Following up on our classic 1100 Katana brake job, today we have a very special machine in the Mutsuzawa factory: the GSX1200S “Oil-Cooled Katana,” an absolute masterpiece custom-built by the specialists at Unicorn JAPAN. Because this oil-cooled brute packs serious modern power, the braking system must be flawless. We completely stripped down the rear caliper and master cylinder, which had accumulated road grime and suffered from hardened rubber seals over the years. After deep cleaning the fluid channels, we rebuilt the entire rear setup with fresh OEM seals and pistons. Verdict: The pedal feel is now incredibly responsive and solid, allowing the rider to easily modulate the bike’s massive torque. Preventative maintenance is the key to enjoying classic styling with modern oil-cooled performance!
