BASIC BRAKE SYSTEM ± Rear Disc Brake
35A-26
3. Clean the piston and insert it into the cylinder with the
special tool.
4. Be careful that the piston boot does not become caught,
when lowering the caliper assembly and install the guide
pin to the caliper.
5. Start the engine, and then depress the brake pedal two
or three times strongly. Then stop the engine.
6. Turn the brake disc forward 10 times.
7. Use a spring balance to measure the rotary-sliding
resistance of the hub.
8. Calculate the drag force of the disc brake [difference
between the values measured at steps 1 and 7].
Standard value: 34 N
9. If that drag force exceeds the standard value, disassemble
the piston assembly. Then check the piston for
contamination or rust, and confirm if the piston or the
piston seal is deteriorated, and if the lock pin and the
guide pin slide smoothly.
