Performance Machine Calipers

PM Vintage 4 Piston Caliper 125X4R

PM Vintage 4 Piston Caliper 125X4R

With this caliper Performance Machine has brought modern braking technology to one of their original calipers that put PM on the map for American made HD braking systems back in the seventies. The Vintage caliper gets its braking power from PM‘s proven 4-piston internals, but features styling cues from the original Dual Action Cast caliper. The reminiscent, CNC-machined fins give it a classic style while keeping the caliper cool and providing optimal braking power with no flex.

The 125X4R caliper was originally developed for the race track and has since become an industry standard for billet calipers and is definitely the most imitated. This legendary four-piston dual action-caliper utilizes a two pad design to increase swept pad area of contact on disc surface which means more consistent and controlled braking power with less effort at the hand lever. The best option for cost conscious High Performance street or race bikers.

PM 4 Piston Caliper 137x4 DBO (Direct Bolt On)

PM 4 Piston Caliper 137x4 DBO (Direct Bolt On)

These calipers feature four pistons with two different piston diameters. The differential bore size compensates for uneven pad wear. It has integrated mounting brackets which directly bolt (= DBO) to 1984–up front ends, except on models with narrow fork and laced wheel.

PM 6 Piston Caliper 112x6B DBO (Direct Bolt On)

PM 6 Piston Caliper 112x6B DBO (Direct Bolt On)

These calipers feature six pistons with three different piston diameters and more braking power than the 4 piston version. The differential bore size compensates for uneven pad wear. Also the pads wear longer because of their extra thickness. It also has integrated mounting ears which directly bolt (= DBO) to 1984–up front ends with 11.5” or 13” brake discs. Exception: models with narrow fork and wire wheel. Due to lacking space this application did not find the engineers' approval.
