14 Bolt Disc Brake Caliper Mounting Brackets (C&C Axle)

14 Bolt Disc Brake Caliper Mounting Brackets (C&C Axle)

Running a larger rim size is necessary with dually wheels, I have been told some 17" wheels will clear the caliper or converting to standard single steel wheel 15" with a minimum 4" back spacing

Here is the bracket so many of you asked us to make, it works on the Cab & Chassis 14 Bolt Axle ('73-87). This bracket uses the '75 Chevy 3/4 Ton Front rotors and calipers just like the rest of the 14 Bolt Disc Brake brackets we make, it simply has the different offset required to run on a Cab & Chassis Axle. These make the 14 bolt Disk Brake Conversion easy! They are sold in pairs and made of 3/8" plate. They are bent and do not require spacers like the ones other companies make.

After '99 all bets are off, the newer model 14 Bolt axles have a variety of patterns & offsets, use a weld on bracket for a newer 14 Bolt axle. 

*NOTE* If longer studs are needed, usually dually studs are long enough or Dormin #610-301. Double check stud diameter, the rotors recommended for these brackets require a stud with 5/8" knurled diameter with 9/16" lug diameter or they will need to be drilled for larger diameter studs. Be sure to have minimum 5/8" lug nut thread engagement

Dan on 2-27-2018 Asked: Im wondering if i have to put the quantity (1) or (2) for a pair of brackets ? Thanks

Answered: These brackets are sold in pairs, so you need quantity (1) for one axle.
robby on 1-22-2018 Asked: these are for a 14 bolt semi floater 6 lug correct? just making sure thanks!

Answered: No these brackets are for the dual rear wheel full float 8 lug 14 bolt axles with at least 19" wheels. We currently do not have a kit for the semi-float 14 bolt, though you may be able to make your own with a weld on bracket and 12.5" diameter 6 lug rotor.
Jay on 1-19-2018 Asked: Do these work on the semi float 14 bolt axle as well or just the full float axle?

Answered: These particular brackets are only for the full float Dually axles. We do not offer anything for the semi-float 14 bolt axles for disc brake conversion.
Greg F. on 11-18-2017 Asked: I would like to put these on an axle with dual wheels. the description states it won't work with duals. My question is why? Is there a rim to caliper clearance issue? or something more complex? I already have these for my SRW truck, best thing I ever bought for the brake system.

Answered: The offset on the factory dual wheels contacts the caliper. If you have a 19" or bigger dually wheel, they will clear.
