DISASSEMBLY
15-INCH TYPE
1. Clean mud and foreign particles from the caliper body assembly and the support.
CAUTION: Be careful not to allow foreign particles to enter the brake hose connector.
2. Place a wooden block in caliper body as shown in the figure to prevent piston from jumping out and avoid being damaged.
3. Gradually supply compressed air via installation hole of brake hose to force the piston out.
4. Remove the piston boot.
5. Remove the piston seal from caliper body cylinder.
CAUTION: Do not damage the cylinder and piston seal groove.
