Looking to buy some refurbished brake calipers from my local euro car parts, some have a 54mm piston size (Sierra) and some have a 60mm piston size. I want to make sure I get the right ones, how dod I tell what piston size I need?
thanks

54mm ones are for 240mm vented discs (ordinary sierra's)

60mm ones are for 260mm vented discs (ABS, XR4, V6 & 4x4 sierra's)

check them against your old ones though (sometimes they arn't in the right boxes!)
