The Right Stuff 1964-74 GM A/F/X-Body W/ Disc & Disc, Black Booster Master Cylinder Combo Kit - (B81315672)

Once a 1964-74 GM A, F or X-body has discs at all four corners, it needs a booster and master sized to match. This Right Stuff combo pairs an 8" dual-diaphragm vacuum booster with a 1" bore aluminum dual-port master in black, and it comes with the bracket, pedal rod extension and hardware to bolt it in.

Why It's Worth It

• Built for disc/disc setups on 1964-74 A, F and X-bodies
• 8" dual-diaphragm vacuum booster for power assist
• 1" bore aluminum master with 2 ports for a dual-circuit system
• Black finish for a clean, factory-style engine bay

What's Included

• 8" dual-diaphragm vacuum booster and 1" bore aluminum master cylinder
• Mounting bracket and mounting hardware
• Brake pedal rod extension
• Bleeder hoses for bench bleeding

Before You Order

• Disc/disc systems need a matching proportioning valve; a disc/drum valve won't balance the system.
• A vacuum booster needs healthy engine vacuum; big-cam engines may need a vacuum pump or reservoir.
• Bench bleed the master before installing it.
