Abstract
A brake, clutch, or continuous slip device (12) having a pyrolytic carbon composite friction material (108) directly cooled by water or an ethylene glycol/water solution. Coolant of cooling device (12) may be tapped from a radiator (24) for a prime mover (14). The brake, clutch, or continuous slip device includes a plurality of interdigitated friction discs (74, 76) defining confronting friction surfaces (74b, 76B). One or both confronting friction surfaces have the pyrolytic carbon composite friction material bonded thereon. The material preferably has a bulk density of 0.7 to 1.2 grams/cc.
