For rear axle mounted parking brakes (P 30800, P 31100, P 31432 with out JF9):
1. Release parking brake handle and remove connector between front and inter-
mediate parking brake cables. Remove front cable from frame bracket and
floor pan assembly.
2. Feed cable and handle assembly through body and re-attach handle to body
convenient to driver’s comfort range.
3. Feed cable back into frame bracket and making sure tangs lock into position.
Place connector back on front and intermediate brake cables.
4. With lever in the applied position, turn adjusting knob to give 5/8 in. clearance
from forward edge of clevis pin head to end of adjusting slot in bracket.
5. Do not alter rear brake drum adjustment or cable equalizer unless routine ser-
vice is required in order to obtain the desired settings above.
Auxiliary Braking Systems
If add-on braking systems are installed to control either tag axle or trailer braking sys-
tems, the body builder is responsible for the integrity of the system. This may require
running FMVSS certification tests. Any change to the GVWR necessitate, recertification
to FMVSS. Care must be taken to assure that flow rate of the brake fluid is not affected
by the modification, as this could reduce the effectiveness of the ABS system. The rec-
ommendations of the auxiliary brake device manufacture should be followed in making
the modifications. For most systems that require a tap-in is best done near the rear axle
of the vehicle. This allows any proportioning of the rear brakes to be communicated to
the auxiliary brakes. This tap-in should not require more than .02 cu. in. of fluid, and be
capable of withstanding pressures up to 3000 psi. Auxiliary brakes must be capable of
taking the proportion of the braking load, for which, they are designed to provide for the
overall vehicle (combination) irrespective of fade or other operating effects.

Section 1 – Body.
Air conditioning and auxiliary belt-driven equipment installation recommendations:
No alterations or additions to the accessory drive belt system will be warranted on ser-
pentine belt systems.
The serpentine belt type of drive is designed as a total system, incorporating a single poly
V-belt and an automatic tensioner. In this type of system, degrees of pulley wrap, belt
tension, and pulley alignment are very critical factors. Modification is not recommended.
Due to the critical nature of the accelerator system, anyone making modifications or al-
terations assumes complete responsibility for system reliability, performance and com-
pliance to FMVSS 124. Caution must be exercised so that the accelerator cable is prop-
erly routed. Specifications are as follows:
D
Route cable to maximize all bend radii. In no case should bend radii be less than
3 in. (76 mm).
D
Minimum distance from exhaust manifold to be 6.0 in. (150 mm), unless a heat
shield is provided.
D
Do not use accelerator cable or clips to route wires, harnesses or other cables.
Cable sheath must be clipped so as not to pinch inner cable. Cable must not be
loose in clip allowing sheath to move when accelerator pedal is applied and
released.
D
Cable must not be subjected to kinking or routing across any sharp edges.
D
Cable routing must be perpendicular to the surface of the front-of-dash at the
dash fitting. No objects or routings should force cable to have a bend at the dash
fitting. Flexible components (hoses, wires, conduits, etc. ) must not be routed
within 2.0 in. (50 mm) of moving parts or accelerator linkage unless routing is
positively controlled.
D
Caution must be taken so that the accelerator pedal remains properly located.
Guidelines for accelerator pedal locations are as follows:
— Ensure that the accelerator can freely operate from idle to wide-open throttle
position and return. Make sure that the pedal will not hang up on any nearby
items such as carpets, floor, screws, wiring harnesses, etc. Engine cover
should have at least one inch (25 mm) clearance to side of accelerator pedal
with the carpet mat installed. No floor covering should be installed under pedal
area.
— Accelerator to brake pedal relationship has been designed to provide mini-
mum driver movement and should not be altered in any way.
Gasoline engine induction and/or ignition system is certified in compliance with the Fed-
eral Vehicle Emission Standards. Any alterations to the systems or components could
void compliance and render the vehicle illegal. System includes:
D
Fuel system – Sequential port fuel Injection (SPFI), central port injector (CPI) and
associated tubes, hoses and pipes, air cleaner outside air hose, fuel pump and
inlet manifold and fuel vapor canister.
D
Exhaust system.
D
Ignition system distributor and initial spark timing setting, spark plugs, spark plug
wires.
