Info

Replace those old drum brakes with modern rear disc brakes. This affordable rear disc brake kit conversion gives you an emergency brake just like your family car has. The steel caliper bracket welds to your 3" axle tube, so it will fit virtually any application. The calipers accept either GM or Lokar type E-brake cables and are tapped to accept the common 7/16"- 20 banjo fittings. The 11-3/4" x .81" vented iron rotors will give you plenty of stopping power.

Wilwood aluminum rotor hat fits 5 on 4-1/2", 5 on 4-3/4", and 5 on 5" bolt patterns and has a 1.94" backspace.
