T R AILER BRA K E S
Spicer has redesigned its 12
1
/4" trailer axle s-cam
brake for longer life and hard w a re standardization. The redesigned 12
1
/4" brake will now utilize
two coil retention springs from the popular 16
1
/2" series brake, replacing the previously used “U”
spring design.
A d d i t i o n a l l y, a number of significant product improvements have been made to improve shoe life
by increasing material thickness in the rib and roller areas. Brake geometry has been impro v e d
t h rough consistent rib placement and rib-to-table welding.
