BRAKES
[3] SERVICING
Brake Cam Lever Movement
1. Move the brake cam lever by hand to check the side to side
movement.
2. If the movement is heavy, smooth the brake cam with emery
paper.
Actuator Flatness and Bearing Holder Wear
1. Place a straightedge of 150 mm (5.91 in.) or more in length on
the contacting surface of the actuator and the bearing holder.
2. Inspect the friction surface of the actuator and the bearing holder
with a straightedge, and determine if a 0.30 mm (0.0118 in.)
feeler gauge will fit on the worn area.
3. If it will fit, resurface.
Height of Actuator and Ball
1. Measure the dimensions of the actuator with the ball installed.
2. If the measurement is less than the allowable limit, replace the
actuator and balls.
3. Inspect the ball holes of cam plate for uneven wear.
4. If the uneven wear is found, replace it.
Brake Disc and Friction Plate Wear
1. Measure the brake disc thickness and the friction plate thickness
with an outside micrometer.
2. If the thickness is less than the allowable limit, replace it.
