Available calipers are built to accept rotors from .310” to 1.10” thick by part number, with an 11.00” - 14.00” diameter range, the MC4 combines an efficient die-cast body with a forged billet anvil for superior strength under load yet is lightweight at only 3.30 (2.95 without pads) pounds. Supplied with each caliper are our Composite Metallic (CM) high-friction, high static-hold brake pads and are pre-fitted with noise-canceling shields.
