Technical want to convert to disc brakes junkyard parts

what is the easiest and cheapest way to do this on 47 chevy coup

 

get a pair of 6 lug 4x4 front rotors, and make some caliper brackets. Hope you have a lathe to make the hubs and rotors fit each other.

There is not bolt on junkyard setup that I know of.

 

thanks I will leave this one alone,have you heard of a tool for rethread the hub to make it 5 bolt

 

Yes, and no. Hubs can be re-drilled by your friendly neighborhood machinist. There are drill jigs for re-patterning, but those are customarily the same bolt circle.

HAMB'er Rottenleonard makes jigs. He did make a 5 to 4 re-patterning jig, so it is technically possible. I did supply him with the full engineering spec to do it.

His stuff works, as promised, every time, and is exceptionally well made.

 

Used to be you could buy a kit that had a bearing spacer and a caliper bracket, and use 70s Camaro rotors and calipers. I don't know if ECI still makes the kit, that was a long time ago that I did one.

You can also see about adapting later drum brakes, the 51-59 truck Bendix style drum brakes are better than the older Huck style brakes. But if you want 5 lug, you might see if you can use the 51-54 car brakes.

If we had more info about the car, and what you plan to do with it, we might be able to make more useful suggestions. Disc brakes are not necessary, in many cases. I still have drums on two of my four old Chevys.

 

I am sure it has been done many times, but it might also be worthwhile to consider using new parts instead of junkyard parts on something as critical as brakes.

 

A friend of mine adapted datsun 6 lug rotors and calipers.He also had the skill and tooling to make the brackets.
