Rear disc with emergency brake options | 356 Speedster, 550 Spyder, Replica, Automotive Community

Looking to change out current disc on my pan based 1969 IRS CMC Standard to a set of disc with an emergency brake.

Looking at this kit https://www.cbperformance.com/product-p/4622.htm

As usual--very tight drivers side fender/clearance. Anyone use this kit? Yes, I've read the past but the CB Rotohub kit wasn't listed and the article was from 07 I believe.

One answer was it extended by 5mm, one said 10mm, and another said reduced by 1/4 inch.

So looking for options before spring trip.

Other question--- are you still using steel brake lines??

Thanks All,

David

I used the kit from... cal-imports or where ever from my rear discs. The e-brake setup works perfectly without any added width. I have a 67 swing axle. Not sure if it's the same for your setup or not.

David, I'd contact CB and ask them. Then you'll have the straight goods. What make/brand is your old rear disc kit?
