SERVICE POINTS OF INSTALLATION
2. INSTALLATION OF FRONT BRAKE ASSEMBLY
Measure the disc brake drag force after installation of the
brake assembly by the following procedure.
(1) With the brake assembly removed, use a spring bal-
ance to measure the rotation sliding resistance of the
hub in the forward direction.
NOTE
Tighten the nuts in order to secure the disc to the hub.
expand the piston, and then install the caliper body.
(3) Start the engine, and after depressing the brake pedal
hard two or three times, stop the engine.
(4) Turn brake disc forward 10 times.
(5) Use a spring balance to measure the rotation sliding re-
sistance of the hub in the forward direction.
(6) Calculate the drag torque of the disc brake (difference
between measured values in 5 and 1).
Standard value: 70 N (15.4 Ibs.) or less
(7) If the disc brake drag force exceeds the standard value,
disassemble piston and clean the piston. Check for cor-
rosion or worn piston seal.
