How to Repair Hydraulic Boat Trailer Brakes How to Repair Hydraulic Boat Trailer Brakes
Hydraulic boat trailer brakes are the most common variety on the market today. Every boat trailer needs a brake, if you're going to haul more than 3,000 pounds, or even 1,000 pounds in some states. So here is a tutorial on how to conduct basic repairs of these crucial components.
Step 1 - Inspect the Brakes
They need to release fully when the tow vehicle is in motion, and apply fully and to an even extent, whenever the tow vehicle brakes. Use a tape measure to ensure that the rotors and pads are sufficiently thick and undamaged, as well. Also check (by applying rearward pressure to the surge coupler) that the brakes engage properly, and maintain pressure for 10 seconds, to ensure that there are no leaks.
Step 2 - Check for Basic Issues
Is there enough fluid inside the brake's master cylinder? Is there air in the lines? Bleed the lines and adjust the drums. If that doesn't work, remove the brake line from the back of the master cylinder, and press the surge coupler. If fluid doesn't come out, check for obstructions. If you don't find any, replace the master cylinder.
Step 3 - Replace What's Broken
Replace any broken physical components, such as the rotors and pads, according to their individual instructions.
