NUTT Y5 hydraulic brake set for KuKirin G4

The brake set for the front and rear of the KuKirin G4 model contains a left and right NUTT Y5 lever, two black calipers, and hydraulic hoses of different lengths. The signal cables on the levers are intended for the motor cut-off function when braking.

Contents and dimensions

• Front hose: 1300 mm; rear hose: 2100 mm according to the supplier.
• Two NUTT Y5 levers, approximately 180 mm long, with a clamp diameter of approximately 22.5 mm.
• Lever signal cables: approximately 384 mm, with red-marked connectors.
• The shown caliper measures approximately 88.6 × 61.5 × 44 mm; the mounting hole spacing is approximately 52 mm.
• The connecting fittings for the hoses and the screws shown in the photos are included.
• Brake discs are not included.

Fitment and installation

When installing on the KuKirin G4, compare the installation side of both calipers, mounts, the diameter and thickness of the existing discs, and the signal connectors. The hoses must allow for proper routing without tension during full handlebar turns and suspension travel. When converting existing brakes, appropriate adapters may be required; the same bolt spacing alone does not guarantee the correct pad position on the disc.

Installation and use

Installation, hose connection, and bleeding should be performed by a qualified technician. Before use, it is necessary to check for leaks, free wheel rotation, the operation of the motor cut-off, and properly bed-in the pads.
