HARRISON ENGINEERING was, back in 1986, one of the first companies to design and develop a multi-piston aftermarket caliper for Harley-Davidson motorcycles.
Each fully progressive four- or six-piston caliper is precisely CNC machined from lightweight blocks of aircraft quality aluminium alloy. To keep the internal tolerances to a minimum, the caliper pistons are machined from special low expansion aluminium alloy.
Caliper pistons have a hard anodised finish that has the same anti-wear properties as hardened steel. For maximum performance the calipers have one pad for each piston.
