Service Points (CR 20V)

FIGURE 12:

1. Front wheel brake assembly (Figure 12)

^ Coat piston, piston seal, and cylinder bore with clean brake fluid.

^ Replace all rubber parts after disassembly. Do not reuse old parts.

^ Check for deterioration, damage and cracks.

FIGURE 13:

2. Brake pad (Figure 13)

^ Measure the thickness of each brake pad lining.

Standard value 10 mm (0.39 in.)
Service limit 1 mm (0.039 in.)

If brake pad lining thickness is less than service limit, replace both pads as a set.

FIGURE 14:

3. Brake disc

^ Inspect the brake disc surface for grooves, cracks, and rust. Clean the disc thoroughly and remove all rust.

^ Using a dial indicator, check the run-out while turning the brake disc slowly by hand (Figure 14).

Service limit 1 mm (0.0039 in.)

If the brake disc is beyond the service limit, it should be ground within service limit. If it can't be ground, replace the disc.

FIGURE 15:

^ Using a micrometer, measure the brake disc thickness minimum at four points, approximately 10 mm from the outer edge of the brake disc (Figure 15).

Standard value 19 mm (0.75 in.)
Service limit 17 mm (0.67 in.)
4. Tubes and Hoses

^ Check the brake tubes and hoses for cracks, damage and leakage.

^ Tighten all the brake line flare nuts to the specified torque.

5. Brake bleeding

^ The brake hydraulic system should be bled whenever the brake tubes, hoses or other brake systems have been removed or if the brake pedal feels spongy when depressed.

Recommended brake fluid DOT 3 or
equivalent

FIGURE 16:

Bleeding sequence is shown in Figure 16.

Bleeding procedure:

1. Have someone slowly pump the brake pedal several times, then apply steady pressure.

2. Loosen the brake bleeder cap to allow air to escape from the system.

3. Repeat the procedure for each wheel in the sequence shown in Figure 16. When air bubbles no longer appear in the fluid, tighten the bleeder cap securely.
