Why do my boat trailer brakes feel weak or uneven when stopping?

Weak or uneven braking is a common issue on boat trailers and can result from several causes. Addressing the problem quickly is important for safe towing.

Common Causes

• Worn Brake Pads or Shoes: Reduced friction material leads to longer stopping distances.
• Air in the Hydraulic Lines: Air bubbles prevent proper pressure, causing a spongy brake feel.
• Uneven Pad Wear: One wheel may grab harder than another, creating pulling or uneven braking.
• Contaminated Pads or Shoes: Grease, oil, or brake fluid on the pads reduces stopping power.
• Sticking Caliper or Actuator: Corroded or damaged components can prevent smooth brake engagement.
• Low or Leaking Brake Fluid: Loss of fluid reduces hydraulic pressure and weakens braking force.

What to Do

1. Inspect brake pads/shoes for wear or contamination. Replace if needed.
2. Check the brake fluid reservoir and hydraulic lines for leaks.
3. Bleed the brakes to remove air from the system.
4. Inspect the calipers, wheel cylinders, and actuator for corrosion or sticking.
5. Service or replace faulty components to restore even braking power.
