Track Racing Brake Line Kit with Low-Expansion PTFE Hose
Race cars are not kind to brake hoses. The heat builds, the pedal goes soft, and a driver loses tenths. A track brake line has one job: hold pressure and stay out of the way.
Our track racing kit uses PTFE inner tube and 304 stainless steel braid. Expansion is near zero, so the pedal stays high and firm through a full stint. The braid handles the vibration and the stone strikes that come with track life.
Kits are cut to your car's layout. Straight and 90° banjo ends, custom lengths, SAE J1401 certified. Pressure-tested before they leave the shop.Product Details

Product Information
Track braking is about consistency. A hose that balloons even a little shifts the brake bias under hard use. Low expansion keeps the pressure where the driver put it.
The 304 SS braid adds armor. It shrugs off the small impacts and abrasion that rubber alone would not survive over a season.
Tell us the car and the layout — single front lines, rears, full car set. Fittings, angles, lengths all sized to the build. For a brake line that holds up on track, this is the one. Contact JUNZE for a track racing kit.
