What You'll Need
Trailer jack
Brake fluid
New brake pads
Ratchet wrench
Rubber mallet
Vice clamps
Small hose and jar

When you change your boat trailer brake fluid every 2 years, you may also need to replace worn brake pads in your disc brakes. Follow these steps to replace the brake pads in your boat trailer.

 

 

Step 1: Remove 1 Wheel at a Time

Release the wheel's lug nuts before jacking. Jack up the trailer and remove just 1 wheel at a time.

 

Step 2: Prepare the Brake Pads for Removal

Push the brake cylinder piston inside the caliper. Put a vice clamp on the back of the brake caliper, and open the bleed valve, letting the fluid out. Tighten the clamp stem to fit the brake cylinder into the caliper. Take off the brake pad.

 

Step 3: Attach the New Brake Pad

Put the new brake pad in place, and release the vice clamp. Pull the brake cylinder out of the caliper. Fill the cylinder with new fluid and bleed it to make sure it has no air bubbles.

 

Step 4: Bleed the Cylinder

Attach a hose to the brake cylinder and put the other end in a large jar. Pull the handle of the hand brake to release fluid, checking for air bubbles. Top up the fluid again and close the cylinder.
