I think the most important factor is the diameter of the brake disc.
I would like to use this rims: 427_VintageWheels
No chance for brake discs larger than 295 m with these rims on the rear axle.
I also tend towards the AP solution.
But Mark has mentioned another point that I hear often-
Hello, Paul and everybody,
many thanks for the info and the pictures.
In fact I forgot the C5040 brake calipers.
I only tested the CP6600 and CP9441 in CAD.
The CP5040 fit really well with a 295mm/11.60" brake disc in the rim.
Now I have 2 options:
1. AP 4 piston brake calipers with brake disc...
I've been drawing with Wilwood brake calipers.
At AP I didn't find anything that fits.
Now I used Wilwood DP6A Calipers -six piston- max. what fits in.
Disc Diameter 11.00 / 279 mm
Disc Width 1.1 / 28 mm
So it gets pretty tight, only 1.3 mm space at the ends
