Fully progressive 4 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 and 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. Harrison claims this gives a more ‘leading edge bite' on the disc than any two pad, or differential bore calipers.
Its 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.
They are truly progressive calipers, with a direct and sensitive relation between the amount of lever pressure, and the amount of braking power.
These show polished or black anodised calipers not only have ultimate stopping power, they also have the ultimate looks, and are available for almost all models.
Mounting bolts and pads are included with each kit.
Rears are available in both 4 or 6 piston versions, as well as polished or black anodised.
Matching design brake rotors can be found elsewhere.
2004 Sportsters with 3/4" axle will have additional spacers included.
