Brake Maintenance Tips

The following inspections and maintenance procedures can help prevent potential brake problems:

• Check brake fluid level at every oil change. Replace fluid according to vehicle Owner’s Manual recommendations.

The following should be conducted by a qualified technician:

• Inspection of the brake hoses for brittleness or cracking
• Inspection of brake lining and pads for wear or contamination by brake fluid or grease
