Differential bore C4 Calipers?
I have a set of calipers that I purchased for my car thinking that all C4 front calipers had the twin 38mm pistons. The calipers that I have have one 38mm piston and one 40mm piston. Have I been wrong in thinking that all C4's had twin 38mm piston front calipers or do I have something odd here?
Also, where's a good place to purchase rebuild kits for these calipers?
Thank you!
