DESCRIPTION AND OPERATION
Drum Brake
Overview
2006.0 Fiesta 1212006 G250944en
Item Description The drum brake is equipped with an automatic
adjuster which adjusts the brake shoes towards
the brake drum when lining wear occurs.
The adjustment mechanism is equipped with a
bi-metallic strip which prevents undesired
adjustment of the brake shoes when the brakes
are run hot.

DESCRIPTION AND OPERATION
The heat generated during braking is passed to
the bi-metallic strip. If the heat exceeds a critical
point, the bi-metallic strip bends upwards into the
corresponding nib and prevents further adjustment.
After the brake has cooled again, the bi-metallic
strip returns to the initial position. Adjustment is
now possible again.
