Hey Jeff! I saw you bought the DeeMaxx Hydraulic Brake Line item # DE74JR but that doesn't tell me what size your bleeder valve is.

Depending on what size your bleeder valve is you'll most likely need a 1/4" or 3/16" ID piece of plastic tubing. You can use our Powerbuilt Brake Bleeder - Master Kit item # ALL648591 to help you with this. It comes with different size fittings and will attach directly to your bleeder valve. This will make bleeding your brakes a one person job and you won't shoot brake fluid everywhere doing it.

What kind of boat do you have?

Hey Jeff, how did things go using the Powerbuilt Brake Bleeder kit with your boat trailer brakes? Your results could help others trying to match tubing sizes for their bleeder valves.
