Two piece rotor ---- disc + hat is probably the easiest.  There may be something off the shelf that goes to another car that could be made to work (no idea what that is sorry to say).  I had new rotors made for my Alpina race car by Porterfield enterprises.  I already had the hats for both, just needed the rotors made, I sent them my original ones so that they could make exact copies (and eliminate me screwing up any of the measuring/dimensions you would need to supply in order for them to make them without).  There are a number of other places that can do the same.

Thank you. I will keep the info in my notes. Rotors can be custom made if I understand well.

That is correct.

I designed the rear disc brake kit, but I changed the design of the bracket.
It is not necessary to remove the hub.

 

Cut and remove the drum brake backplate.
However, the removed back plate can not be used again.

The brake disc in our kit is machined to the hub.
There is no need to remove the hub as it is not machined.

 

Work will be completed in a few hours, including removing the drum brakes.

 

We plan to sell for $ 1400.
The kit is, calipers, pads, disc rotors, caliper brackets, brake lines, and mounting hardware.
Everything necessary for installation is included.

The caliper is a aluminum caliper and also has a parking brake

Always great that someone takes the time to develop a new product for our cars. Can you tell us more about the kit? What calipers and rotors does it use? Any pictures of the install? Does the bleed screw end up the right way around?

This kit uses the R50 mini calipers and the Opel Astra rotors.

The bleeder does not work perfectly because the caliper is mounted under the suspension arm.
It can be installed even with a 13-inch rim.

 

As we removed for catalog photography, there are only the images before.

Has anyone tried disk brake conversion kit on widened 13 steelies that Ryan Danco makes?

If it is not still available to order, I have some rear disk brake kits for sale.

And what kit do you offer please?

Before you order the VW kit (mine is from Blunt) you should first call your local machine shops to see if they will turn your hubs. I live in Spokane WA, a town of 300,000 people, and I couldn't find anyone to turn my hubs. I ended up doing it myself on my bench grinder - not fun.

That is some fine work.  I am surprised that there wasn't a machine shop that could do it.

I’ve read a few posts about machining the hubs so I thought I would add my experience. Although I haven’t done the conversion yet I do have replacement hubs ready to go. I also recently bought myself a lathe. The other day I decided to have a play and try and machine the hubs. The hub would not fit the lathe with the studs in place so I knocked them out. I doesn’t look like the hub has enough “gripping space” to mount them but my 3 jaw chuck held it fine. I then machined away 😁 and it worked fine.

So, the moral of this story is, if I can do it, only having owned a lathe for a few weeks, then a machine shop can definitely do it! 
However, I think the problem is that when a machine shop hears the words “machining” and “hub” in the same sentence they fear failure of the hub and the ensuing legal action. This is why they say they can’t or won’t do it. Just my theory 🙂

Shops don't want the liability if the hub breaks and somebody gets hurt or killed.  Insurance companies like to sue as well as relatives of the deceased.

My observation is a bit off-topic, but the liability issues are why I decided to stop selling "U-Weld It" cages for the 2002.  We are going to see less and less custom work available for our cars (any cars really) as the "crusty old machinists who don't give a damn about lawyers" phase out of existence. It's a pity, because a lot of projects will get halted because of problems that are fairly simple to repair with the right tools.

 

Okay, back to rear brakes!  I had a machinist turn my hubs down years ago when I converted to rear discs, and it was cheap and quick for him to do with a lathe.  I did knock the studs out before handing him the hubs.

Can someone please tell me where these (blue) go on the Blunt kit? Thanks
