Brake Drag Force Check




BRAKE DRAG FORCE CHECK

1. Remove the brake pad, shim, and clip. (Refer to Brake Pad Replacement.)





2. Using a spring scale, and with the brake pad, shim, and clip removed, measure the hub sliding torque in the forward direction.
3. Install the brake pad, shim, and clip. (Refer to Brake Pad Replacement.)
4. Start the engine, and depress the brake pedal lightly two or three times. Then stop the engine. [Depressing force : approximately 50 - 100 N (11.2 - 22.5 pound)]
5. Rotate the brake disk 10 times in the forward direction.
6. Using a spring scale, and with the brake pad, shim, and clip installed, measure the hub sliding torque in the forward direction.
7. Obtain the disk brake drag force (difference between measured values of Step 2 and Step 6).
Standard value: 68 N (15.3 pounds) or less
 8. If the brake drag force exceeds the standard value, disassemble the brake caliper assembly, and check the fouling/rust on the piston sliding section, piston seal deterioration, and the sliding status of guide pin and lock pin. (Refer to Disassembly and Assembly [Front] or Disassembly and Assembly [Rear].)
