Bringing economy to performance, this brake kit offers drilled and slotted rotors for a $25 upgrade over our standard kits. Front disc brakes provide a significant improvement in braking performance versus the drum brakes your car came with. This complete front disc brake conversion kit fits 1964-72 GM A-Body, 1967-69 GM F-Body and 1968-74 X-Body using your stock disc brake spindles or our new replacement stock height disc brake spindles # 910-34900.

Kit includes 11" diameter vented brake rotor with 5 on 4-3/4" wheel bolt pattern, '69-'77 GM style calipers (7/16"-20 inlets), caliper brackets, brake pads, backing plates, rubber brake lines, and all necessary bearings, seals and hardware for an easy, complete installation onto factory disc brake spindles.

Note:  Brake kit will not fit our 2" dropped spindles # 910-34906 (Camaro with integrated caliper brackets) or stock drum brake spindles. Must be used with stock style disc brake spindles and 15" diameter or larger wheels.


Brake kit fits:

  • 1964-72 Chevelle, Malibu, El Camino
  • 1967-69 Camaro, Firebird
  • 1968-74 Nova, Ventura, Omega, Apollo
If you are going to use this kit on an A-Body Oldsmobile (Cutlass, 442), Pontiac (GTO, Lemans) or Buick (Skylark, GS), it will not directly bolt on to the original spindles even with grinding the .610" off the stud at the top. The lower bolt holes in the original spindles are 7/16" and the bracket and bolts 1/2". The upper bolt holes on the original spindles are 1/2" with the brackets and bolts being 5/8". You will need to replace or modify the spindles.
