The AP Racing CP6750 range of 6 piston brake calipers were developed for the front or rear axles of rally raid vehicles but can be suitable for other vehicles used on rough terrain. The calipers have no external bridge pipe and feature protected bleed screws. This makes them less prone to damage from gravel or other debris. The body is a 2 piece aluminium alloy design and houses stainless steel pistons with dirt seals to protect them. Suitable for disc sizes 320-355mm.Designed for rally raid vehicle rear axlesNo external bridge pipe and protected bleed screws prevent damage from stones and other debrisTwo piece aluminium alloy body for low weight and high strengthStainless steel pistons with dirt seals for added protection from containment ingressCaliper SpecificationsMin Disc Dia320mmMax Disc Dia355mmDisc Thickness28-32mmPiston Dia27.0mm x 2 / 31.8mm x 2 / 38.1mm x 2Piston Area50.1cm²Inlet PortM10 x 1Mount TypeRadialMounting Centes180mmMounting Offset35.0mm (CP6750-1/2/4/5) / 37.0mm (
