How often should I inspect my boat trailer brakes?

Boat trailer brakes should be inspected before each trip and given a more thorough inspection every 3 to 6 months, depending on how often you tow and whether you launch in freshwater or saltwater.

What to Check Before Each Trip

• Brake Pads or Shoes: Look for uneven or excessive wear.

• Rotors (Disc Brakes): Ensure they are free of heavy rust or scoring.

• Drums (Drum Brakes): Make sure the shoes are not worn or contaminated, and check the flush kit (if equipped) for function.

• Wiring and Hydraulic Lines: Inspect for corrosion, cracks, or leaks.

• Brake Actuator: Confirm smooth operation and check for signs of sticking.

Seasonal or 3–6 Month Inspections

• Disc Brakes (standard on Venture trailers where applicable):

  • Inspect calipers for sticking or corrosion.

  • Check stainless hardware for signs of wear (saltwater accelerates corrosion).

• Drum Brakes:

  • Use the flush kit regularly to clear out saltwater deposits.

  • Remove drums periodically to check for shoe wear, spring tension, and contamination.

• Brake Fluid: Replace at least every 12 months — sooner with frequent saltwater use, since moisture intrusion is common.

• Tires and Hubs: While inspecting brakes, check hubs for heat and ensure bearings are properly greased.

Saltwater Considerations

Saltwater launches significantly increase the risk of brake corrosion. To extend brake life:

• Rinse brakes thoroughly after every saltwater launch (disc brakes must be hosed down manually; drum brakes may have flush kits).

• Inspect more frequently — every 3 months or mid-season if you tow often in saltwater.

• Upgrade to stainless steel or galvanized components where possible for maximum durability.
