The AP Racing CP6740 range of 4 piston brake calipers were developed for the 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 aluminium pistons with dirt seals to protect them. Suitable for disc sizes 285-355mm.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 strengthAluminium pistons with dirt seals for added protection from containment ingressCaliper SpecificationsMin Disc Dia285mmMax Disc Dia355mmDisc Thickness28mmPiston Dia31.8mm x 4Piston Area31.6cm²Inlet PortM10 x 1Mount TypeRadialMounting Centes180mmMounting Offset35.0mmMounting Hole Dia12.15mmAP Racing  CP6740 calipers are handed and sold individ
