The Right Stuff 1958-70 GM Car/Truck Disc/Drum Dual Bail, Dual Reservoir Master Cylinder - (DBMC09)

A single-pot master cylinder means one leak takes out every brake on the car. This Right Stuff dual-reservoir master for 1958-70 GM cars and trucks splits the system into two circuits, so a failure at one end still leaves you brakes at the other. It's set up for a disc/drum system, the most common layout after a front disc swap.

Why It's Worth It

• Dual reservoir design separates front and rear circuits for a real safety margin
• Configured for disc front / drum rear systems
• Dual bail wire clips hold the cover down securely and keep the vintage look
• Covers a wide 1958-70 GM car and truck range

Before You Order

• Confirm whether your car runs power or manual brakes and that this unit matches your booster or pedal setup
• A disc/drum system needs correct proportioning, and the rear drum circuit typically needs a residual valve if the master doesn't have one
• Converting from a single-reservoir master usually means new hard lines and a distribution or proportioning valve
• Check your lines' fittings against the master's ports before installation
