 Air Disc Brakes PAN™17

2 15

With the introduction of pneumatic 1

disc brake PAN™17 in 1996, WABCO
pionieered the control of tangential taper
wear. Since then, the patented taper wear
compensation in combination with the
advanced single-piston technology has
passed the test of time. Our success in 13
17.5” wheel applications demonstrates
the effectiveness of this technology. 12

PAN™19 WABCO set new standards
both in the trailer and in the mid-class
truck segments. At only 32 kg it is still
one of the lightest brakes of this size. 11

 Hydraulic Disc Brakes

WABCO’s Hydraulic Disc Brakes

for parking and emergency brake
applications have proven their reliability
for more than 40 years.
These brakes are ideal for installation
in a wide variety of Off-Highway Wheel
Loaders, Haulers, Lift Trucks and
Platforms as well as Rough Terrain
Cranes. The brakes are activated
automatically when the system pressure
falls below 1480 psi / 102 bar release
pressure, offering maximum safety and
reliability.
