Brake Upgrade

Nice work, Michael, and what a perfect reason to upgrade! I think it may be high time for someone to set up Tour de Smo 2019 (paging @Lane Anderson).

I’ve been running CB’s “zero offset” rear discs since 2005, but mine are wide-5, so it’s a completely different setup.

You may want to confirm that the late Porsche drilling setup truly is “zero offset”. Mine add about 1/2” per side.

Ron and Maddie are handling this year's event as it is going to be in their neck of the woods.  I pinged them a while back and they said they'd get going on it.

Mike--there has been a lot written here about the problems with the B C Performance rear disc brake kit.  I had my troubles too when the inner steel part of the hub separated from the aluminum outer part.  Drove all the way home to AR from Richmond VA with the separation.  The hub has to spin some part of a circle before"catching" going either forwards or backwards.  This is a long time flaw with this part.  I swapped out my defective hubs from a solid steel one from Socal imports.  It was plug and play and was a direct replacement for the bad one.  Someone posted that the problem with separation is eliminated if the brake kit is properly torqued.  Mine was perfectly torqued because I was previously warned about this before the rear discs were installed  still went South. 

Socal also makes a complete rear disc conversion which I'd recommend if starting from scratch.   The steel hubs weigh more but the extra pounds means nothing to the engine I have and I doubt a 1600 cc Type I would loose much either.

I wouldn't drive a Speedster replica without discs at all four corners.  We have enough safety issues to worry about without not taking care of one issues that can be fixed.

Good luck with your car!

Mike;

Is your CMC body standard or the wider CMC?  And have you done the "butt sag" improvement?

This is a known problem with the CB wide five brakes, and it was good you brought it up, Jack.

However, Michael is running Fuchs, and so has late Porsche drilling brakes, which are a completely different thing. This is good information to have out there, but not necessarily relevant to the brakes he is looking at. The late Porsche drilled hubs are not made out of aluminum, they are ferrous.

I think the big question with these brakes is whether or not they add with as compared to stock drum brakes. 

Stan---I didn't understand about the Fuchs---thanks for the clarification.

Thanks for the replies guys and yes Art I did address the but sag. The problem is one of clearance from the face of the hub to the outboard fender well and with the CMC body fault of less clearance on the left side vs right, its close to the tire and rubs at times. I've filed the inner lip for more clearance as well.

Stan,I'll have to check with CB as I had heard about the zero/true offset in their setup. I think that may be "Pay once cry once" is what I'm looking at here but putting a grand into the setup would hinder my interior budget.

If no one has had any experience with the Super Stopper setup I may be on my own on this experiment but its the cost of a ham sandwich vs the whole pig.
