Disk brakes to suit your 64-66 Mustang

We were the first to produce a disk brake adaptor. 14 years ago I noticed that the bolt spacings on the HQ Holden
calipers were similar to the original Kelsey Hayes calipers. I set out and designed an adaptor plate that resembled
the original Kelsey Hayes plate. It was interesting that when I had the original analysed, it was a very poor grade
of casting. The adaptor plate we had made was made out of SGI cast, the best available.

I used these for many years until the foundry closed, what to do now? The result, a re-design and an improved
adaptor plate made much cheaper. We now use Commodore calipers, Falcon rotors XW-XY, XA-XC, but you have to
change the wheel bearings and cones to XW-XY.

If you have styled steel wheels, you will need XW-XY or XA rotors with the small centre. A change of rims is
necessary to clear the caliper, ordinary Ford rims will do.

Why can’t I use Falcon stub axles and discs on my 64-66 Mustang?

The reason is that the angle of the tie rod is different even though it looks the same.

Cost of the adaptor plates $133 a pair.
