Rear Brake Rotors

[BBK]

My Mk IV is in the shop having much work done to it.   The shop has advised that the rear rotors are warped.  I understand that the rear calipers and pads are from a Peugeot, but not sure if the rear rotors are a Peugeot part or from another car.   Does anyone know what car the rear rotors come from and where the rear rotors can be sourced?  Was it a Peugeot part or from another car, or a part unique to the AC Mk. IV and made by AC?   Thank you!

The rear rotor are like the front rotor specially made for Autokraft. Maybe you ask Steve Gray from AC Heritage whether he has some left.

   Great suggestion.  Thanks!

Rear calipers are Peugeot 205 I believe.
   The rotors are bespoke and hard to obtain - AC Heritage will be able to point you in the right direction.
   Good luck,

Is there sufficient meat left on them to skim them? Might keep you on the road until replacements can be obtained at least?

   Nik, I understand the rotors are on their last legs, without enough left on them to salvage

Robert,
   I once had the same problem with Greyhound front discs and took them to a specialist firm who treated them, then built them up with metal spray and finally ground them back to new dimension. I had a choice of material and specified something with a small chromium content to give better corrosion resistance. I was doubtful of the whole process and wondered about suitable pad material, but actually it worked well and was not expensive. Whatever you do hang on to the old discs. If all else fails machining new discs to pattern will be possible.

   Barrie, thank you for the interesting and informative post.  I did not know that such a process was possible to build up the old rotors.  I will certainly look into this if all else fails or will look into getting new discs machined if need be.   Thanks again.

In my early car the Peugeot 505(504,604, Talbot Tagora)rear floating calipers are used.

   For the rotors i found a company here selling all kind of brake parts. They told me that I need to find a production rotor with the same or close to the dimensions of the original Autokraft parts.
   
   These actual availlable parts have to have 4 holes, same diameters (inner and outer)thickness and dish. This company will redrill the disks for 6 pin pitch circle and if necessary adjust the inner diameter.
   
   If the dish is different they will produce a adapter part to mount the existing or new calipers to the hubs.
   For this adapter they offer a fast 3D printed sample, made to the dimensions the customer has to deliver to check the fitment before ordering the machined metal part.
