Are the rear-calipers on FC's with 4-piston front calipers the same as FC's with single piston front calipers? I know that FC's with 4-piston front calipers have vented REAR rotors, and single piston front caliper models did NOT have vented rotors.

 

Good question!! Now I am interested as well!! Bump for ya!

 

Try looking up the part number for each caliper on the Mazdatrix website. Same number = same part.

 

The rear calipers have e-brake cables attached to them.

 

ANSWER, no they are different. The width is different and they are slightly larger, although the pads are the same for all rear.
