Reassembly

Rear Disc Brake Caliper Check:Disc

WARNING:

Failure to take proper precautions when assembling the brake caliper can result in brake system failure, which could lead to an accident.

- Clean each part before installation using the same brake fluid as that in the master cylinder reservoir. Never use any other brake fluid or volatile solvent.
- Before installing the brake caliper to its carrier, install each slide pin after greasing the hole in the carrier and check for smooth movements in the thrust directions.
- Apply brake fluid to the piston seal before installing it to the cylinder.
- Fit the piston seal securely into the groove of the cylinder making sure it is not twisted.

Before install piston to brake caliper, check piston and caliper as below.

- Check all around piston for rust, corrosion and any other damage. If it is found faulty, replace piston or brake caliper.





- Push in adjusting bolt (1) by hand and move lever to check that adjusting bolt (1) moves smoothly in the arrow direction.
Also, check adjusting bolt (1) for any damage. If it is found faulty, replace brake caliper.
