I was looking at the specifications on different brake calipers for some projects, and it occurred to me that the data would be of interest to others.
As far as I could tell these were total weights, including pads. Weights were taken from the catalogs indicated, except the Nissin caliper which was weighed by a friend.
If anyone has dimensions for a brake I've not listed send it to me and I'll add that to the list.
Price comparisons are up to you and your FLD (friendly local dealer).
