Preventive Maintenance

Every month 8,000 kms, or 300 operating hours, check brake chamber push rod travel; stroke should be as short as possible without the brakes dragging or the push rod binding. Adjust manual slacks if necessary. Due to the different operating conditions, adjustments may be necessary at earlier intervals.


Every 6 months, 50,000 kms, or 1,800 operating hours, lubricate all slack adjusters and clevis pins with manufacturer's recommended lubricant. Check for worn clevises, clevis pins, clevis pin bushings and control arm/bracket wear. Failure to replace worn components will increase chamber stroke. Lubrication and inspection may be necessary at earlier intervals due to different operating conditions.
