Hi Everyone, I was thinking of converting my 1972 GS 350 from power drum brakes to disc brakes (all 4 wheels). I contacted CPP (Classic Performance Parts) and they said the Chevelle brakes are the same as the Buick brakes. I was wondering if anyone knows if this is true and does anyone know if the CPP brakes are good. Any help is much appreciated.
Anything that works like the Right Stuff kit will work on either because they have the same backing plate pattern on 10, 12, c-clip and bolt-in axles.
They have the same bolt pattern yes, but some kits mount the caliper bracket on the axle flange side some mount behind. The ones that mount on the outboard won't work with bolt in axles. Plus you need to make sure when you install the kits that do mount inboard you properly take up the thickness of the old brake shield cause if not it will pull the axles into far putting pressure on the axle bearings
The kits like Right Stuff come with a shim the proper thickness to replace the old backing plate. Unless piecing a kit together from junkyard parts, the manufacturer should be able to easily explain what it fits and how it mounts. Here's an image of the Right Stuff kit and the shim is about the middle of the pic.
Some of the kits that mount outboard have the bracket designed to replace the bearing retainer plate,and will bolt flush to the end of the juicing. Some other kits,like the One Inline Tube sells,which is an improved copy of The Right Stuff,supplies a shim plate that mounts in between the end of the housing,and the retainer plate,just like the drum backing plate did. Inline Tube kit,with black calipers and plain rotors pictured. Same as the The Right Stuff kit except they clearanced the caliper bracket to fit over the tube better. Both companies are starting to offer them with a dust shield,like the one Knucklebusted pictured above,but I don’t opt for those.
Right stuff also makes a kit with no rear brake which is what I'm leaning towards for our racecar. Part # AFXRDM1 for plain rotors and calipers or AFXRDM1S for black power coat drill and slots, and stainless hoses for like 100 more
