Grease on brake pads

What causes it and how to fix it

When it comes to trailer maintenance, one issue that can affect your trailer's braking system is the accumulation of grease on the brake pads.

This can compromise your trailer's ability to stop safely, posing a significant risk.

In this section of our knowledge base article, we will explore the causes of grease buildup on trailer brake pads and provide solutions to address this issue.

Causes of Grease Buildup on Trailer Brake Pads

  1. Overly Lubricated Wheel Bearings: Excess grease in wheel bearings can get pushed out onto the brake pads when the wheels heat up during operation.
  2. Leaking Seals: Damaged or worn-out seals can allow grease to leak onto the brake components, including the brake pads.
  3. Improper Lubrication: Applying grease haphazardly or using the wrong type of grease in the wheel hubs can lead to excess grease reaching the brake pads.
  4. Grease Contamination: Contaminated environments or improperly sealed wheel hubs can introduce contaminants like dirt or water, which can mix with grease and find their way to the brake pads.

Solutions to Grease Buildup on Trailer Brake Pads

1. Regular Maintenance:

  • Schedule regular maintenance checks to inspect wheel bearings and seals.
  • Follow manufacturer recommendations for lubrication intervals and use high-quality, appropriate grease.

2. Proper Lubrication:

  • When greasing wheel bearings, use a grease gun and follow a proper greasing procedure to prevent over-lubrication.
  • Ensure that the wheel hubs are properly sealed and protected from contamination.

3. Seal Replacement:

  • If you notice leaking seals, replace them promptly to prevent grease from reaching the brake pads.
  • Inspect and replace seals during routine maintenance or when any signs of wear or damage are detected.

4. Clean and Degrease:

  • If grease has already contaminated the brake pads, remove the affected components and clean them thoroughly using an appropriate brake cleaner.
  • Inspect and, if necessary, replace the brake pads.

5. Upgrade to Sealed Hub Assemblies:

  • Consider upgrading to sealed hub assemblies, which are designed to prevent grease leakage and contamination.

6. Professional Inspection:

  • If you are unsure about the condition of your trailer's braking system or how to address grease buildup, seek the expertise of a professional trailer mechanic.

Grease buildup on trailer brake pads can compromise safety and effectiveness.

By understanding the causes and implementing the appropriate solutions, you can ensure your trailer's braking system remains in top condition, providing reliable stopping power when you need it most.

Regular maintenance and attention to detail are key to keeping your trailer safe and reliable on the road.
