METHOD ONE (requires two people)
Close all bleed screws.
Start with the wheel furthest from the master cylinder. Slip a transparent bleed hose on the bleeder stem and place the other end
of the hose in a clean container which is partially filled with fluid at all times.
The first person depresses the brake plunger SLOWLY (take 3-5 seconds). THEN the second person opens the bleed screw. He then
closes the bleed screw BEFORE the first person SLOWLY releases the plunger (3-5 seconds). Continue until there is no evidence of
air in the bleed hose. Continue with remaining wheels working from the longest to the shortest distance from the master cylinder.
Top off master cylinder as needed to prevent reintroducing air into the lines.
IMPORTANT:
1) Depress plunger slowly
2) Open bleed screw
3) Close bleed screw
4) Release plunger slowly
METHOD TWO (one person)
Attach bleed hose to rear wheel as in method one. Open bleed screw. SLOWLY depress plunger (3-5 seconds). Repeat until line is
air free. Close bleed screw. Top off master cylinder as needed to prevent reintroducing air into the lines.
Repeat with remaining wheels.
DANGER: Contamination with dirt, water, petroleum products or other materials may result in
brake failure or costly repairs.
1) Remove the shield. Use a 9/16" wrench to remove the (2) 3/8" x 1" serrated hex head bolts from shield.
2) Loosen the 1/2" nut on the plunger pin. Use a 3/4" wrench.
3) Rotate the plunger rod to adjust.
- For more aggressive braking action turn the plunger rod counterclockwise. (This will lengthen the assembly)
- For less aggressive braking action turn the plunger rod clockwise. (This will shorten the assembly)
DANGER: Do not adjust all the "Play" out of the plunger system. This will cause the brakes to be activated at
all times and over heat the drums causing failure.
NOTE: This braking system is to assist the pull vehicle in the braking mode, not to take the place of it.
The braking plunger system should have approximately a 1/4" of "play" when adjusted for level road travel.
4) Tighten the 1/2" hex nut to keep plunger rod in place.
5) Put the shield back on and tighten both 3/8" x 1" SF hex bolts.
