More power!! Like our other high performance rear brake systems, the 1277-0073 kit was designed to be the ultimate setup for the intended application. The race inspired small bore/large bore piston combination in this caliper allows it to compensate for uneven pad wear and create a near perfect pad to rotor contact.
