Hi Gentleman-

Thanks for your time and knowledge. I looking for advise on the easiest and most cost effective way to convert my 1966 Dynamic 88 drums to discs.

This was a option for 67 B bodies, but it seems difficult to find conversion kits for B bodies. Will the 67 parts bolt on 66 or are there spindle issues ect.

Regards-

The 67-70 disk brake spindles will bolt onto the 65-66 cars. Unfortunately, your chances of finding a set are nearly zero, and even if you do, no one makes replacement rotors. Scarebird makes an aftermarket kit.

 

Thanks Joe-

So basically Scabbard or nada.

 

Scarebird, and yes.

 

I've got a set in Oregon on a 1970 parts car. The downside that's been discussed is if a rotor gets too worn to turn again then finding a replacement rotor is really difficult. But if want to consider it I do have the complete setup. John

are the parts interchangeable with Impala of the same year?

 

If they were, this wouldn't be the problem that it is.

FYI, the 65-70 Impala chassis, suspension, and brakes are COMPLETELY different from those on the full size Olds. Nothing interchanges.

 

How difficult is the plumbing if one just goes to a dual master cylinder?

 

Thanks Joe.

 

If you decide to stay with the drum brakes and just upgrade to the dual reservoir master cylinder that's not too difficult. The reason I say that is the 1967 had dual reservoirs and the 66-67 were similar in many ways. So you should be able to purchase the parts from a 1967 and add them to your car. Do you have power drum in the front now?

Maybe Joe can help confirm or correct. But I believe all you need to do is replace the master cylinder, brake lines from the master and the distribution block. Not sure, you may also have to replace the rod that goes from the booster into the master cylinder.

The only issue is getting a master cylinder that has the correct depth in the piston to fit on the existing booster. Raybestos P/N MC36234 has the shallow piston hole for boosters with the short pushrod between the booster and M/C. Raybestos MC36236 has the deep piston hole for boosters with the long pushrod. Both have the same 1" bore as the original.

 

Sure appreciate your knowledge and time Joe.
