Recently the question was asked “why would you run Jetta calipers on our 5000 lb rigs”? I remember is when so far as to say using Jetta was putting you life and everyone on the road with you in jeopardy. I am going to try to show you what I have learned the last few years.
The Jetta I’m talking about are the rears from 2006-2013

First the piston bores
Jetta= 1.57 , 41mm
Eurovan = 1.47 , 38mm

Second the ebrake arm from center to center of cable

Jetta = 2.300
Eurovan = 1.75

Third pad size: almost the same square inch but one big difference. The eurovan has the old style spring that pushes up on the caliper. So if the bushings in the guide pads ware out your pad is offsetting the caliper.
The Jetta uses the caliper carrier to hold it in place.

Caliper material
Jetta = aluminum
Eurovan = cast steel

Also note in the pics the ears that hold the pad. The Jetta are wider but that could be because of the material differences. Also note the top ear is thicker on the Jetta. Carrier pin spacing is almost the same if not the same.

Carrier pin size is the same

I will upload pics and add them here later
