Disc Brakes
Dexter Axle manufactures two types of disc brakes, the floating
caliper and the fixed caliper brake. With both styles, the disc
brake uses friction pads astride a ventilated rotor which is
attached to the wheel hub. When the brake is actuated, the pads
are pressed against the sides of the rotor causing drag to slow
the rotating disc. This action converts the kinetic energy (motion)
into heat. The heat is dissipated rapidly by the ventilated disc.
The floating caliper brake uses piston(s) situated on one side of
the brake rotor. Hydraulic fluid pressure pushes against the
piston(s) to apply the inboard
brake pad. As the inboard pad
exerts force against the rotating
rotor surface, the caliper moves
laterally towards the trailer
frame and in turn applies an
equivalent force to the outboard
brake pad against the rotor
surface. As the lining material
wears, the caliper will
automatically maintain the
proper lining to rotor clearance.
The floating caliper design is
used on Dexter 10,000 and
12,000 lb. axle models.
Disc brake effectiveness is the same going either in a forward or
reverse direction. All Dexter disc brakes should be actuated with
a braking system that is capable of providing a maximum
hydraulic pressure of 1,600 psi.
