Smooth Installation from Start to Finish

Layout made sense, and the included hardware was more than enough. Took less than 3 hours to fully plumb both axles. Brakes engage evenly now.

Top-Quality Components, Well-Packaged

All steel lines were straight, no dents. Rubber hoses are thick-walled and the brackets fit snug. Everything labeled and organized—great attention to detail.

No Leaks After Installation and Bleeding

Followed the layout and used thread sealant on fittings. After bleeding, brakes felt firm and responsive. Zero seepage after 500+ miles.

Excellent for Disc Brake Conversions

Used this to plumb a full disc brake system. The tees and union created a balanced feed to all four calipers—no pressure imbalance.

Exactly What My Drum Brake System Needed

Replaced old corroded lines on a boat trailer. The corrosion-resistant steel and UV-rated hoses give me confidence in wet conditions.
