Product Description
The Juin GTP-4 is a hybrid hydraulic disc brake caliper system that combines cable actuation with sealed hydraulic braking. This set includes two opposed 4-piston calipers for front and rear use. Each caliper has a forged 6061 aluminum body with CNC-machined piston bores, 7075 aluminum pistons, and a mineral oil hydraulic circuit. A tool-free adjustment knob helps set piston clearance as the pads wear. The calipers are designed for short-pull brake levers and Post Mount or ISO frames. DP43 and SP43 pads are supported; rotors are not included.
