GENERAL DESCRIPTION

All 1967 models are equipped with a new split brake

system as a safety feature. If a wheel cylinder or brake

line should fail at either the front end or rear end of

the vehicle, the operator can still bring the vehicle to

a controlled stop. The system is designed with separate

hydraulic systems for the front and rear brake using

a dual master cylinder (fig. 1). The design of the master

cylinder is similar to that used on the 1966 Corvette

in that it has two entirely separate reservoirs and outlets

in a common body casting. The front reservoir and outlet

is connected to the front wheel brakes, and the rear

reservoir and outlet is connected to the rear wheel

brakes. Two pistons within the master cylinder receive

mechanical pressure from the brake pedal push rod and

transmit it through the brake lines as hydraulic pressure

to the wheel cylinders. The filler cap is accessible from

inside the engine compartment.

A new brake pipe distribution and switch assembly

is mounted below the main cylinder. The front and rear

hydraulic brake lines are routed from the main cylinder,

through the brake pipe distribution and switch assembly,

to the front and rear brakes as shown in Figure 2. The

switch is wired electrically to the brake alarm indicator

light on the instrument panel. In the event of fluid loss

in either the front or rear brake system the indicator

on the instrument panel will illuminate red. (The indi-
cator will also' be illuminated when the parking brake is

applied.)

On Camaro models equipped with air conditioning, the

rear brake hydraulic line is routed through a pressure

regulator valve mounted on the left frame side rail

(fig. 3). The valve controls the hydraulic pressure to

the rear brakes resulting in the correct pressure balance

between the front and rear hydraulic systems.

The self-adjusting brakes (fig. 4), used on both front

and rear of all models, are the Duo-Servo single anchor

type which utilize the momentum of the vehicle to assist

in the brake application. The self-energizing or
self-

actuating force is applied to both brake shoes at each

wheel in both forward and reverse motion. The brake

shoe linings are bonded to the shoes.

Wheel cylinders are the double piston type permitting

even distribution of pressure to each brake shoe. To

keep out dust and moisture, both ejads of each wheel

cylinder are sealed with a rubber booC The wheel

cylinders have no adjustments.

The Chevrolet, Chevelle, and Camaro parking brakes

have a foot operated ratchet type pedal mounted to the

left of the steering column. A cable assembly connects

the pedal to an intermediate cable by means of an equal-

izer, where the adjustment for the parking brake is

incorporated. The intermediate cable attaches to the

Tune Up should be checked whenever the Air Injection

Reactor System seems to be malfunctioning. Particular

care should be taken in checking items that affect fuel-air

ratio such as the crankcase ventilation system, the car-

buretor and the carburetor air cleaner. Carburetors and

distributors for engines with the Air Injection Reactor

System are designed, particularly, for these engines;

therefore, they must not be interchanged with or replaced

by a carburetor or distributor designed for an engine

without the Air Injection Reactor System.

CLUTCH LINKAGE ADJUSTMENT

There is one linkage adjustment (clutch fork push rod

or pedal push rod) to compensate for all normal clutch

wear.

The clutch pedal should have
1-1/4"
free travel (meas-

ured at clutch pedal pad) before the throwout bearing en-

gages the clutch diaphragm spring levers. Lash is re-

quired to prevent clutch slippage which would occur if the

bearing was held against the fingers and to prevent the

bearing from running continually until failure.

With Nuts (A) & (B) loose on Rod (D)
&
before installa-

tion of Clutch Pedal Return Spring
(E),
apply approximately

5 lbs. load in direction of arrow (F) to eliminate clear-

ance between throwout bearing and clutch fingers. Move

Rod (D) in direction of arrow (G) until Clutch Pedal Arm

makes contact with Bumper Stop on instrument panel

brace. Run Nut (B) toward Swivel until dimension (X) is

9/32". Tighten Nut (A) to lock Swivel (C) against Nut (B).

Install Clutch Pedal Return Spring (E).

The foregoing procedure will provide a free pedal

travel of 1" to
1-1/2"
measured on a perpendicular from

the crown of the, pedal pad to the bare metal toe pan.

Chevelle Linkage Adjustment (Fig. 2)

1.
Disconnect spring between cross shaft lever and

clutch fork.

4.
Hold the clutch fork rearward to move throwout

lightly against clutch release fingers, then adjust rod

length until rod just touches ,its seat in the fork.
5.
Adjust locknut to obtain approximately 3/16" clear-

ance between nut and rod sleeve end.

6. Turn the rod with wrench, until the nut just comes in

contact with rod sleeve end, then hold the rod with

wrench and tighten locknut.

7.
Check free pedal travel at pedal (1" to
1-1/2"
is

proper clearance). Readjust if necessary.
