Brake brand Textar has added 16 expanding locks to its current portfolio, thus covering almost every required application.
Textar says in addition to good manoeuvrability, attention must also be paid to the material quality of this safety component as imprecise production quality can result in the hand brake not holding under load, such as when parked on an incline.
The expanding lock is a drum brake component. However, vehicles with disk brakes on the rear axle may be affected in the same way if the hand brake is designed as an internal drum brake.
Damage to the expanding locks is quite common in this design, as the parking brake linings barely wear and the condition of the hand brake can only be determined when the brake discs are removed.
Several vehicle manufacturers recommend replacing the expanding locks every time the brake shoes are replaced or every four years.
“There is no better way to ensure the full effectiveness of the hand brake, because when the brake shoes are replaced, the expanding lock can usually be easily checked and replaced”, says Dalibor Stojnic, global category manager at TMD Friction. “It is essential that workshops always use premium quality spare parts to ensure high safety standards.”
