GM Mid-size to 1949-54 Chevy Spindle, Deluxe Kit Drilled/Slotted

Works on all 1949-1954 GM car spindles that have been machined per the included instructions. For straight axle hot rod builds only, not for use on 1949-1954 GM car use. This kit will not work with stock steering arms, you must use aftermarket arms. Not for use with 1949-1954 GM truck spindles. Will work with Speedway Motors forged 1949-1954 GM car spindles with no machining required. Single 2-13/16-inch piston GM-style “Midsize” calipers use commonly available replacement pads. Disc brake style wheels are required for proper caliper clearance when upgrading from drum brakes. Street friendly organic brake pad compound for long pad and rotor life. Performance brake pad upgrades available separately for those wanting increased stopping power. Drilled and slotted 11-inch vented rotors create superior stopping power to drums, especially for heavier cars. Rotors feature standard GM 5 on 4-3/4 wheel stud bolt pattern. Includes everything you need to convert from drum to disc brakes with all new parts. Add Disc Brakes to Your Straight Axle Hot Rod with Bolt-On Ease We understand that the traditional straight axle hot rodder is going to want to keep the look of early Ford brakes and their finned drums on their Model A or 32 roadster if at all possible. However, we know there is a large base of builders that want their classic looks but with modern handling, braking, and comfort. Face it, if your hot rod is a miserable ride that will not stop you are not going to want to drive it. We get it. For those enthusiasts, a small amount of leeway in their hot rod’s traditional looks is acceptable to make it a fun long-distance cruiser that can be safely operated in today’s traffic. One of the top safety upgrades we see is updating these straight axle hot rods with front disc brake kits. Speedway Motors offers several complete disc brake conversion kit options with everything you need to get the job done on your spindles, and if you do not have spindles for your hot rod straight axle setup, well, we have those as well! Everything You Need and Everything New Time is our most precious commodity and something that we cannot ever obtain more of. So why waste your valuable time scouring parts stores, junkyards, and Internet forums for DIY “piece it together” disc brake conversion solutions that will only cause you frustration in the garage and lead to further delays and parts searching? Speedway Motors, a leader in street rod parts, understands how important your time is, which is why we have done all the time sensitive research and parts sourcing to build the most complete Model A brake upgrade with our straight axle drum to disc brake conversion kit package for early Chevy spindles that works, is easy to install, and does not require you to mortgage a kidney just to buy it! Our disc brake kit features 11-inch vented rotors that are paired with the popular 1969-1977 GM “Midsize” single piston disc brake caliper. These calipers use a 2.8125 (2-13/16-inch) diameter piston and offer excellent stopping power in a floating caliper design. We include standard organic brake pads, but the caliper can be upgraded with any D52 performance pad of your liking should you desire a bit more pad “bite” in your system. Also included in our kit are new brake fluid hoses, bearings, seals, dust caps, and all mounting hardware. This brake kit will add 8-1/2 inches overall to your straight axle’s center-to-center distance of your king pins. Meaning, if you are running a 48-inch axle, your overall width once installed will be 56-1/2 inches. This may be more or less than your current setup depending upon current brake package and wheel spacers. This kit requires a minimum of a 14-inch "disc brake" wheel, however we recommend a 15-inch wheel with a 2.80-inch hub I.D. that is lug-centric for proper clearance. The caliper mounting brackets provided fit ’49-’54 Chevy car spindles are quite stout to prevent any caliper flex during hard braking
