2.2 FEATURES OF WET DISC BRAKES
A. REDUCED DISC WEAR
Although wet discs are worn by approximately several
tens of microns depending on the initial contact in ini-
tial period (50 hours or so) of use, almost no wear
occurs afterwards. This means that brake adjustments
are eliminated.
B. STABLE BRAKING
Since the brake discs are immersed in transmission
oil, loss is rarely caused even after repeated braking
and a stable braking force is obtained.
C. PEDAL STROKE DOES NOT CHANGE UN-
DER INFLUENCE OF HEAT.
Unlike internal expanding type brakes, in which the
drum-to-shoe clearance increases due to thermal ex-
pansion and results in increased pedal stroke, the wet
disc brake provides a constant pedal stroke.
