IMPORTANT
Ensure the tab stops that the collars come into contact with are not bent in any way.
This will affect how the plunger pin sits when the opposite brake is applied. Any
deformity in the tab could cause the plunger pin to become misaligned with it's own
steering arm during the application of the opposite brake.
Both left and right steering arms should be pulled back to their rear most limit
before the plunger pin adjustment is made. On earlier models you should use both
hands to pull back on each arm to ensure they are back in the rear most position.
Photo BR-3 Later models utilize a double spring behind the plunger in the master
cylinder which will provide plenty of spring tension to push the steering arms back
fully.
1. Sitting in the vehicle driver's seat, en-
sure sure that the steering handle bar is
parallel with the dash. Plunger pins
should be threaded so they are in con-
tact at the back with the steering arms.
Place the collar tightly up against the
welded tab stop and secure the set
screws with blue LOCTITE
Setting Plunger Pin Adjustment
2. Thread the plunger pins until the master cylinder plunger piston is flush with the
casting of the master cylinder. Photo BR-4 Re-tighten all plunger pin jam nuts.
Recheck that steering handle bar is parallel with dash and repeat procedure if neces-
sary.

IMPORTANT
If you have been servicing the brake system, add fresh clean DOT 5 brake fluid and
rebleed the brakes, purging all air from the brake system. Reinstall the master
cylinder covers. When complete, apply steering input to both sides to " pump up the
brakes". Recheck plunger setting and adjust as necessary.
7. Re-adjust the hand brake lever cable until any slack has been removed between the
two steering arms and is on the verge of engaging the brakes. Tighten the brake
cable jam nut.
