Drum Brakes - Daewoo MATIZ Service Manual

4E – 2 REAR DRUM BRAKES

DRUM BRAKES

This drum brake assembly is a leading/trailing shoe de-
sign. Both brake shoes are held against the wheel cylin-
der pistons by the lower return spring and the fixed
anchor plate near the lower return spring. When the
brakes are applied, the wheel cylinder pistons move
both shoes out to contact the drum. With forward wheel
rotation, the forward brake shoe will wrap into the drum
and become self-energized. With reverse wheel rota-
tion, the rear brake shoe is self-energized. Force from
the brake shoes is transferred to the anchor plate
through the backing plate to the axle flange. Adjustment
is automatic and occurs on any service brake applica-
tion. Do not switch the position of shoes that have been
in service, as this may render the self-adjustment fea-
ture inoperative and result in increased pedal travel.
