First, inspect the master cylinder bore with clean brake fluid, insert the secondary piston assembly bore, and insert the primary piston. Next press the pistons into the cylinder bore using a wooden drift, insert the new retaining ring into the groove in the cylinder bore, and move the piston backward and forward. After that lubricate the seal ring, insert the seal on the shaft into the cylinder bore, and install the brake fluid reservoir to the master cylinder. Finally, install the master cylinder assembly, and bleed the braking system.
