the clamping nuts on the

flange plates have openings with
spring snap covers to simplify brake adjustment.
Toe-board clearance very seldom
needs to be adjusted. The pedal stop,
located in the brake main cylinder, is permanent. Before attempting
to adjust this stop, be certain that the pedal returns to the full
released position freely, with no binding, and that the pedal retracting
spring has not lost its tension.
TOE-BOARD CLEARANCE-PASSENGER CARS
1. Loosen check nut on the eccentric
bolt.
2. Turn the eccentric bolt, Fig. 12, in the
proper direction to secure
7/16-inch toe-board clearance.
3. Tighten check
nut. |

Tighten
the clamping nuts by hand and place the
fixture in a bench vise. Then tighten down the clamping nuts firmly with a wrench
and remove the stop pin from
the die. The tubing is now
firmly gripped in the die and ready for the first flare forming
operation.
3. Using the flare forming tool
having the concave die, insert the
forming tool in the die and strike firm blows, using a one pound
hammer, until the shoulder of the tool contacts the top of the die. The
cross section drawing. Fig. 10, shows the first step in forming the
double-lap flare. |

TOE-BOARD CLEARANCE-TRUCKS
1. Loosen the check nut on the rear of the

push rod.
2. Remove clevis pin and turn the clevis
attached to the main cylinder
push rod, Fig. 13, in the proper direction to secure 1/4" toe-board
clearance—measurement being
taken between pedal arm and
underside of toe-pan.

pound hammer, until the shoulder of the tool contacts the top of
the die. The cross section drawing. Fig. 11, shows the second and final
forming operation in making a double-lap flare. |
