f)
Install the short “elbow” tube from the adapter tee (female nut) to the larger port of the
master cylinder.
g)
Install line from distribution block to adapter tee. Line can be looped into a circle if too
long.
h)
Install line from distribution block to the smaller port of the mater cylinder. Line can be
looped into a circle if too long.
i)
Securely tighten all fittings before bleeding the system. BE SURE TO CHECK FOR
LEAKS AT ALL CONNECTIONS WITH THE PEDAL APPLIED. FOR MAXIMUM LINE
PRESSURE, BEFORE DRIVING THE VEHICLE.
j)
After installation is complete, the pedal height and firmness may be adjusted for the
“best feel” by slightly lengthening or shortening the pushrod one or two turns
maximum. This adjustment can be made without breaking the hydraulic lines.
However, care must be taken that brakes release properly when the pedal is released.
A dragging or locked up brake is the result of a pushrod that is too long.

Filling and Bleeding system
a)
It is advisable to replace the brake fluid if the color is brown or muddy. This is due to
water that has been absorbed by the fluid which will eventually corrode the brake lines
and master cylinder. This absorbed moisture can also cause vapor lock situation under
extreme braking conditions. Flush system with clean brake fluid and replace with a
good grade of disc brake fluid DOT 3 or DOT 4.
b)
The simplest and most effective way to bleed your brakes is to use the gravity bleeding
approach as follows:
1)
With calipers installed, make sure all fittings are tight and master cylinder is
topped off.
2)
Open one bleeder screw and observe for several minutes. At first the fluid will
begin to escape with intermittent air bubbles. When the air bubbles stop and a
steady flow of fluid is observed, close the bleeder and repeat process on other
side of vehicle.
MAKE SURE TO KEEP A CLOSE WATCH OVER THE FLUID LEVEL INSIDE THE
MASTER CYLINDER DURING THE BLEEDING PROCESS. NEVER LET THE
RESERVOIR RUN DRY. ALWAYS KEEP IT AT LEAST 1/3 FULL.
3)
After bleeding all four wheels and topping of the master cylinder make 20- 30
applications of the brake pedal. If a hard pedal is experienced, no further
bleeding is required. If pedal is spongy, repeat bleeding process until a hard
pedal is achieved.
4)
With all bleeding complete, there should be approximately 3/4” to 1” of end play.
5)
Power brake cars will experience a “drop off” of the pedal when the engine is
started. This is a normal condition that signifies the booster is working.
6)
Pedal end play can be adjusted under the dash on non power cars and between
the booster and master on power brake cars.
FINAL INSPECTION
a)
Once a hard pedal is achieved, all fittings and connections must be inspected to make
sure there are no leaks. Also check the level in both reservoirs of the master cylinder
and top off if needed.
