Bleed sidecar line first then motorcycle rear wheel.

Open bleeder nipple by rotating counterclockwise about one-half turn. With master cylinder full of fluid at all times, slowly depress foot pedal repeatedly until fluid flows from bleeder nipple free of air bubbles. Add fluid to master cylinder to bring to original level. Close bleeder nipple. Do not re-use fluid unless it is clear and free from sediment. If it is impossible to bleed all air from system, the master cylinder check valve is faulty and a master cylinder repair kit must be installed.


When the brake is properly adjusted, the foot pedal should move freely about 1-1/2 in. before the plunger (4) contacts piston in master cylinder and brake takes effect. This contact may be easily felt if pedal is depressed by hand.

Pull rubber boot (5) away from end of master cylinder housing to expose piston push rod link. Holding push rod link in center of opening, work brake pedal (1) back and forth by hand to determine free play.

Adjustment is made by loosening lock nut (3) and turning plunger (4) to shorten or lengthen piston push rod (2) as needed. Tighten lock nut (3).
