- 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 installing 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.
