Drum Brake Lubrication Points
Whether you have an older vehicle that uses drum brakes, a newer vehicle that uses them for cost-efficiency, or a smaller vehicle like an ATV, there are few key places that need lubrication. Here are a few helpful hints that will help you lubricate your drum brakes properly.
- Don't ever put lubricant on the inside of the drum where the shoes/pads contact the drum. This will cause the brakes to stop working, and could be very dangerous.
- Use lubricant on the backing plate. You'll find small ridges where the shoe rests; these can be sanded lightly with a grinding wheel, and then lubricated.
- The adjustable star-wheel that separates the shoes can be prone to freezing, so it should be lubricated.
- The parking brake usually uses the rear drum brakes in your car, so lubricate the parking brake cable and any linkages or moving parts.
- Make sure you lubricate the separator located about halfway up the shoe.
- Use lubricant anywhere you find metal-to-metal contact between moving parts, such as where the shoes slide.
- Don't use dry film lubricant where the lube might contact rubber or plastic seals.
- Don't overlubricate -- you don't want excess lubricant dripping into places it shouldn't go.
