Reputable 340 Rebuild Kit

Helloo everyone!!

If anyone is still following this thread, im wondering if there are any good disc brake kits out there for the same 66 barracuda.

Ive done some research and ive read that if i do rears, bolt patterns change, wheel size change and a whole lot of other things change..

Im not looking forward to do that so im focusing on a FRONT disc brakes WITH power boosters and the whole nine yards.
If i do fronts, will the aftermath be the same as the rear? Change in tires? Bolts? Etc..?

Keep in mind im still building the 340 with the six pack.. I've seen a couple of photos with boosters and the six pack in early A's.. im just unsure of the size of the booster and all that.

Any recommendations, tips, help, pricing, suggestions are all beneficial, welcomed, and appreciated!!

Drum brakes are giving up on me so either i redo those or go for the next best thing..


Thanks guys, I always appreciate the help from here!


There's a guy on the forum here that rebuilds brake and suspension parts. I bought a few sets of reconditioned kelsey hayes 4 piston disc brake set-ups complete from him, just attach to upper and lower ball joints. If he still has any, it's reasonable to get them. With the Kelsey Hayes, you can keep it with the stock 4" bolt pattern. The KH discs were stock from 67-72 (I'm not sure about the early A's)

In 73 they switched to the 4.5" bolt pattern single caliper disc brakes. They are common with the B & E body front disc brakes. If you want to convert to 4 1/2" bolt pattern, then go with the single piston calipers. They will require going with the 73 and later upper control arm which will bolt in place of the early one.
