1. Failure to complete the BRAKE FLUID FILLING AND BLEEDING procedures promptly after installation may result in internal master cylinder corrosion and cause brake failure A WARNING Use only fresh brake fluid from a sealed container DO NOT reuse fluid After filling and bleeding remember to refill the actuator Failure to maintain an adequate fluid level may cause brake failure Fill the system with DOT 3 4 heavy duty brake fluid The braking system may be bled manually or with a vacuum or pressure brake bleeding system Both types of brake bleeding equipment should be available at your local automotive jobber Follow manufacturer s instructions Brake Fluid Filling and Bleeding 5a After completing the Installation instructions remove the master cylinder cap and fill the reservoir to three quarters full with DOT 3 brake fluid DO NOT allow brake fluid to contact painted surfaces since it will damage the finish Wipe up any spills immediately and wash the area with water 5b If you choose to manually bleed the system an assistant makes the job easier Manually pull the actuator out to fully extended position Loosen the four bolts on the breakaway lever see Figures 3 amp 4 Remove the back two bolts rotate the two breakaway locks to the side and tighten the front two bolts Pull the lever forward until nearly vertical and return normal operating position Repeat this stroking action until the air stops bubbling inside2. 17 0778400 Damper 2 18 0829800 Damper Pin 2 19 0830100 Pushrod Block 1 20 0799700 Cotter Pin 1 8 X 1 2 21 0794800 Bolt 5 16 X 1 2 NC Grade 5 4 22 1248900 Star Lockwasher 5 16 4 23 1507000 Cylinder Cover 1 24 0827100 Bolt 3 X 3 8 NC Grade 5 2 25 1255200 Star Lockwasher 3 8 2 26 0797600 Hex Nut 3 8 NC 2 27 0794900 Bolt 5 16 X 5 8 NC Grade 5 6 28 0838800 Right Hand Cylinder Bracket 1 29 0838900 Left Hand Cylinder Bracket 1 30 1054100 Breakaway Lever Assembly 1 31 1055200 Weather Seal 1 32 1052700 Right Hand Breakaway Lock 1 33 1052600 Left Hand Breakaway Lock 1 34 1055500 S Hook 2 35 0776800 Safety Chain 1 36 1297600 Inner Slide 3 Lunette Eye Page 10 of 14 MODEL 20 ACTUATOR PARTS LIST cont ref Parts Diagram on page 9 Key Part Number Description Qty 37 1058200317 Inner Slide Leveler Channel painted 1058200183 Inner Slide Leveler Channel plated 38 1807800 Clevis Hitch For 1 Pin 39 0909300 Bolt 4 1 4 X 5 8 NC Grade 5 40 1040500 Locknut 5 8 NC 41 0793800 Lockwasher 5 16 STD 6 42 1209800 Orifice Connector drum brake 1 8 NPT 1 1209900 Orifice drum brake earlier 1 2 NF thread master cylinders 43 0774500 Gasket used with 1209900 orifice 1 44 1278800 Inner Slide 2 5 16 Coupler painted 44 4488400 Inner Slide 2 5 16 Coupler plated 45 1882000 Adjustable Ball Coupler 2 5 16
