A135-1 and A135-3 Revision 2

a) Install the master cylinder assembly to the firewall using the fasteners used to retain

the original master cylinder.

b) Install adjustable pushrod, provided in kit, between the master cylinder piston and

brake pedal assembly using the original clevis pin and a new cotter pin.

c) Lengthen or shorten pushrod to obtain approximately 1” of “free play” at brake pedal.

Further adjustment will probably be required after system is filled and bled to provide

greater line pressure (longer) or to relieve a locked brake condition (shorter).

IN THE CASE WHERE ONLY A FRONT DISC BRAKE CONVERSION IS

INSTALLED IN CONJUNCTION WITH A REAR DRUM BRAKE SYSTEM, AN

ADJUSTABLE PROPORTIONING VALVE MA

Y BE REQUIRED FOR BRAKE

BALANCING. A VALVE MEETING THESE REQUIREMENTS IS AVAILABLE

FROM SSBC AT AN ADDITIONAL COST (PART NO. A0707) AND MAY BE

LOCATED ANYWHERE IN THE LINE RUNNING FROM THE REAR PORT OF

MASTER CYLINDER TO THE REAR BRAKES.

d) Due to the various types of master cylinders that Jeep used, we have included a

master cylinder with ports on both sides. You can choose which side will best fit your

needs and install plugs in the opposite side. An adapter fitting has also been included

in the kit for most pre-1977 Jeeps that had different size fittings.

e) The front port of the new master cylinder is for the front brakes and the rear port is for

the rear brakes (regardless of which side of the master cylinder you use).

9) 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 a 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 fluids are acceptable.

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 at a time starting at the wheel farthest from the master

cylinder and working your way back around the wheel closest to the master.

With bleeder screw open, observe bleeder. 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 for several seconds, close the bleeder valve and move on to

the next wheel.

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

FULL.
