5.2.7 MECHANICAL BRAKES ADJUSTMENT
During use of trailer abrasive friction covering of brake drums is subject to wear. Piston
stroke extends, and exceeding braking force limiting value declines.
TIP
Proper cylinder piston stroke should be between 25 – 45 mm.
Braking force decreases also when the operating angle of the brake cylinder piston (5), in
relation to the expander arm (1), is wrong – figure (5.4). In order to obtain the optimum
mechanical operating angle, the cylinder piston fork (6) must be installed on the expander
arm (1) in such a manner as to ensure that the operating angle at full braking is about 90°.
IMPORTANT!
Incorrectly adjusted brake may cause rubbing of brake shoes against brake drums, which
may lead to faster wear of brake linings and/or brake overheating.
