Big Bore Master Cylinder ALL41064
Master cylinder with large 1-1/4" bore
works well on vehicles that require
increased volume for proper braking
or as an option when experiencing excessive
pedal travel with standard 1" bore Corvette style
master cylinders. Cast iron master cylinder features
a deep hole piston for use with manual or power brakes. Front brake port accepts 3/16" steel brake line with 3/8"-24 inverted flare nut. Rear brake port accepts 1/4" steel brake line with 1/2"-20 flare nut (using included adapter) or 9/16"- 18 flare nut by removing adapter.
Master Cylinder Adapter Fittings ALL41012
Fittings adapt master cylinders or combination valves with 1/2"-20 and 9/16"-18 ports to accept 3/16" inverted flare brake line with standard 3/8"- 24 fittings. Kit includes one of each fitting.
Pedal Rod Extensions
Steel extensions
have 3/8"-24
threads and are often used to connect the brake pedal to the master cylinder or booster using a female rod end or a clevis.
Switch is plumbed into the brake
system and is activated by closing the
electrical connection with rising brake
pressure (60-120 PSI). Designed for easy
two wire connection, one "+" supply and the other to power brake lights or a brake light relay. Switches are rated at 4.5 amps and have 1/8"-27 dry seal mounting threads.

Brake Pedal Clevis ALL41026
Description
Residual check valves hold a small
amount of pressure in the brake system
to keep the brake system functioning
properly while helping to maintain a firm
pedal. Maintaining system pressure pre-
vents fluid from returning to the master cylin-
der when the master cylinder is positioned lower than or close to the same height as the calipers or wheel cylinders. Proper system pressure also keeps piston and wheel cylinder seals ex- panded, creating a positive seal and brake pads seated against the rotor. Valves include two 3/16" inverted flare fittings.

Distribution Block with Proportioning Valve and Brake Light Switch ALL48037
Distribution block connects
brake lines from the master
cylinder to front and rear
brakes with the added benefit
of a rear proportioning valve
and built-in pressure activated
brake light switch. The propor-
tioning valve may be adjusted
to limit rear brake pressure to help prevent rear brake lock-up. Block ports have 3/8"-24 threads that accept 3/16" inverted flare style fittings. Block includes installation instructions, fit- tings, pigtail wiring harness and boot.
