Brake Drag Force Check
BRAKE DRAG FORCE CHECK1. Remove the brake pad, shim and clip.
2. Using a spring scale, measure the hub sliding torque in the forward direction with the brake pad, shim and clip removed.
3. Install the brake pad, shim and clip.
4. Start the engine, and depress the brake pedal forcibly two or three times. Then, stop the engine.
5. Turn the brake disc 10 times in the forward direction.
6. Using a spring scale, measure the hub sliding torque in the forward direction with the brake pad, shim and clip installed.
7. Obtain the disc brake drag force (difference between measured values of item 2 and item 6).
Standard value:
68 N (15.3 pounds) or less [Front (Except RALLIART)]
85 N (19.1 pounds) or less [Front (RALLIART)]
68 N (15.3 pounds) or less [Rear]
8. If the brake drag force exceeds the standard value, disassemble the brake caliper assembly to check for fouling/rust on the piston sliding section and piston seal deterioration, and confirm whether the guide pin and lock pin slide properly.
