Hope is phasing out its powerful V2 hydraulic disc brake design for 2013, replacing it with an even more powerful V4 caliper. The key change is a return to a four-piston layout with bigger and longer pads for more surface area – and more grip – than the old two-piston configuration. Hope also says the new caliper is stiffer for improved lever feel and power.
Naturally, Hope machines the aluminum V4 caliper in-house as a single piece and the updated form features an array of subtle cooling fins and a big window to help dissipate heat. The matching levers are unchanged for 2013 and still feature machined aluminum construction (with nearly everything done in-house) plus independently adjustable reach and pad contact.
According to Hope, the new V4 is slightly lighter than the V2 with complete single brake weights starting at 400g.
