How to choose your MTB brake hoses?

Brake hoses transmit the power you apply to your brake lever directly to the MTB brake calliper. They must regularly withstand pressures of around 25 bar, or even more, during intense and sudden braking. It is therefore essential to ride with brake hoses in good condition and compatible with your brakes to avoid any unpleasant surprises.

Types of brake hoses

Even if the way of assembling the hose with the MTB brake lever looks identical across all brands, there are nonetheless small differences. The diameters are not always the same and the fitting systems A can differ.

In general, it is not possible to mix parts from different brands. Moreover, even within a brand, different models will not be compatible and will require specific hoses and fittings.

Some brands offer "aviation"-type hoses inspired by those used in aeronautics. More reliable and resistant, these hoses feature a metal braiding B and are covered with a plasticised coating; this is what distinguishes them from so-called "classic" hoses.

Which brake hose should you choose?

As mentioned above, it is essential to choose the model compatible with your specific brand and model of MTB disc brake.

If the routing of your brake hose requires tight bends, or risks being subject to folding or abrasion, opt for an aviation-type hose, which is more resistant to pinching or tearing.
