Regulation Of Main Brakes - PRONAR T780 Translation Of The Original Instructions

Bearings replacement, lubrication and repairs connected with brake system and wheel axle
should be entrusted to specialist service provider.
Inspection of slack and technical condition of wheel axle bearings must be performed
after the first month of use, and then every 6 months of trailer use.

5.2 REGULATION OF MAIN BRAKES

Brakes regulation is necessary when:
• as a result of wear of brake shoe linings between lining and drum there is excessive
slack and reduced braking effectiveness.
• wheel brakes do not brake evenly or simultaneously.
If brakes are correctly regulated, braking of trailer road wheel takes place simultaneously.
Brakes regulation consists of changing setting of axle shaft expander arm (1) in relation to
expander shaft (2). To do this rotate regulation screw (3) in appropriate direction to displace
the expander lever:
• to the rear - if brake brakes too late,
• forward - brake brakes too early.
