Using the following method, measure the drag force of the
disc brake after installation of the brake assembly.
4. With the brake assembly removed, use a spring scale
to measure the rotary sliding resistance of the hub in
the forward direction.
5. Clean the piston and then using the special tool, push
the piston into the cylinder (caliper).
6. Apply repair kit grease to both sides of the inner shims.
Specified grease:
Brake grease SAE 5310, NLGI No. 1

the shim.
7. Start the engine, depress the brake pedal firmly two to
three times and stop the engine.
8. Give the brake disc ten turns in the forward direction.
9. Using a spring scale, measure the rotary sliding resistance
of the hub in the forward direction.
10. Obtain the drag force of the disc brake (the difference
between the values measured in 9 and 4).
Standard value: 70 N (15.4 Ibs.) or less
11. If the drag force of the brake exceeds the standard value,
disassemble the piston and check for dirty or corroded
piston sliding surface and deteriorated piston seal.
