15.HANDLEBAR/FRONT WHEEL/FRONT BRAKE/ Downtown 125i FRONT SHOCK ABSORBER/STEERING STEM Loosen the bleed valve and pump the brake lever. Stop operating the brake when no more fluid flows out of the bleed valve. Brake fluid filling/Air bleeding Do not mix different types of fluid since they are not compatible. Fill the master cylinder with DOT 4 brake fluid to the upper level. Connect a commercially available brake bleeder to the front caliper bleed valve. Check the fluid level while bleeding the brake to prevent air from being pumped into the system. When using a brake bleeding tool, follow the manufacture's operating instructions. Pump the brake bleeder and loosen the front caliper bleed valve. Add fluid when the fluid level in the master cylinder is low to prevent drawing air into the system. Repeat the above procedures until no air bubbles appear in the brake hose. Close the front caliper bleed valve and operate the front brake lever. If it still spongy, bleed the system again. 15-13
