For those looking for a sleeker looking caliper we also have Harrison 4 and 6 piston calipers in the "Slimline" design. Like the original Harrison Billets every caliper is precisely CNC machined from lightweight, aircraft quality aluminum alloy with special hard anodized low expansion aluminum alloy caliper pistons and one brake pad for each piston. Harrison claims this gives a more 'leading edge bite' on the disc than any two pad, or differential bore calipers. It is also especially beneficial in wet conditions, because the first set of pads sweep water off the disc, while the following 2 or 4 pads are still 'biting' on the disc. That removes the effect of the calipers 'skating' on the disc, and then braking sharply and suddenly when the disc becomes dry. Harrison Slimline calipers are truly progressive, with a direct and sensitive relation between the amount of lever pressure and the amount of braking power. These show polished, chrome or black anodized calipers are available in 4- and 6-piston designs and do not only provide ultimate stopping power, they also have super sleek looks. The front calipers bolt straight to the front fork bottom leg, and the rear sets include the mounting bracket. Stainless steel shims to space the caliper to the disc, and mounting bolts are included with each kit. Matching design brake rotors can be found elsewhere in this catalog.
