1955-58 Bel Air 4 Wheel Power Disc Brake Kit, Zinc/Cast Iron | Pirate Jack | DBK55581012FSLX-GMFS1-211

1955-58 Bel Air / 210 / 150 / Nomad / Impala · Front & Rear Discs · Drilled & Slotted Rotors · Stainless Hoses · 8" Dual Zinc Booster · Disc/Disc Valve · Part # DBK55581012FSLX-GMFS1-211

Ditch the drums at all four corners and stop like you mean it. This complete Pirate Jack package converts your 1955-58 full-size Chevy to power disc brakes front and rear, with 11" drilled & slotted rotors, large loaded GM calipers and stainless steel braided hoses. Under the hood, a factory-look power brake package does the work: an 8" dual zinc booster, a 1.125" bore dual bail cast iron master cylinder and a brass disc/disc proportioning valve kit.

The front kit bolts directly to your factory spindles, and the rear calipers have a built-in emergency brake. Every part is brand new. Nothing is rebuilt or remanufactured. Want to finish the job right? Add a made-to-order original steel or stainless steel front to rear brake line kit and replace your old front and rear lines at the same time.
