The torque of the bolts securing the brake hose brackets may not be sufficient, and therefore, the bolts may loosen and the brackets could fall. If the bracket falls, the brake hose could be damaged, resulting in reduced braking efficiency.
The torque of the bolts securing the brake hose brackets should be checked, and the loose bolts should be tightened to the appropriate torque. Unsecured brake hoses because of missing bolts should be replaced with new ones.
