Maintenance Procedure. ОThe fluid level must be checked often during the chang­ing operation and replenished with fresh brake fluid

NOTE

О The fluid level must be checked often during the chang­ing operation and replenished with fresh brake fluid. If the fluid in the reservoir runs out any time during the changing operation, the brakes will need to be bled since air will have entered the brake line.

1. Open the bleed valve [A].

2. Apply the brake and hold it [B].

3. Close the bleed valve [C].

4. Release the brake [D].

• Remove the clear plastic hose.

• Tighten the bleed valve to the specified torque, and install the rubber cap.

Torque -Caliper Bleed Valve: 7.8 N-m (0.8 kgf-m, 69 in-lb)

OFollowthe procedure below to install the brake fluid reser­voir cap correctly.

OFirst, tighten the brake fluid reservoir cap [B] clockwise [C] by hand until the resistance is felt fully; then, tighten the cap an additional 1/6 turn [D] while holding the brake fluid reservoir [A] body.

• After changing the fluid, check the brake for good braking power, no brake drag, and no fluid leakage.

• If necessary, bleed the air from the lines.

Bleeding the Brake Line

The brake fluid has a very low compression coefficient so that almost all the movement of the brake lever is transmit­ted directly to the caliperfor braking action. Air, however, is easily compressed. When air enters the brake line, brake lever movement will be partially used in compressing the air. This will make the lever feel spongy, and it will be a loss in braking power.

Be sure to bleed the air from the brake line when­ever brake lever action feels soft or spongy, after the brake fluid is changed, or whenever a brake line fitting has been loosened for any reason.

• Remove the reservoir cap, and fill the reservoir with fresh brake fluid to the upper level line in the reservoir.

• With the reservoir cap off, slowly pump the brake lever several times until no air bubbles can be seen rising up through the fluid from the holes at the bottom of the reser­voir.

○Bleed the air completely from the master cylinder by this operation.
