This is a rebuilt rear caliper, if only ordering one, please specify side. This does not include pads. You must send us your old caliper(s). If you or your mechanic would like to have the rebuilt ones on hand to just swap them out in one fell swoop, we will send rebuilt ones to you first, charging a core charge of $175 per side. Order Part Number G11/01/CORE. This $175 will be refunded when we receive back your core in rebuild-able condition.
