The innovative complex shape of the body removes unnecessary bulk, improves brake and fluid cooling, and actually decreases deflection. Four Thermlock® thermal barrier pistons reduce heat transfer to the brake fluid, and the staggered bore size front calipers provide more even engagement with improved pad wear. Hard-anodized inside the piston bores and on the surface with Type III aluminum-oxide ceramic finish for durability and equipped with single-point bleed technology and low-profile bleed screws for easy serviceability. No-bind pad retaining pins (spare included) hold your choice of multiple 0.80” thick Wilwood race compound brake pads for extended service life.
