Question: 1 / 400

What should be done if you notice that one of the glad hands is leaking?

Disconnect the glad hands and reattach them

Ignore it if there's no loss of air

Replace it with a new glad hand

If a glad hand is leaking, it is critical to address the issue promptly and effectively, as this can compromise the air supply to the trailer's brakes. The best course of action is to replace it with a new glad hand. A leaking glad hand indicates that there is an issue, such as a compromised seal or damage to the glad hand itself, which can lead to further losses of air pressure and potential brake failure.

Merely disconnecting and reattaching the glad hands does not resolve the underlying problem that is causing the leak. Ignoring the leak, even if there's currently no noticeable loss of air, could lead to more significant issues down the line, including brake system inefficiencies or failures. Sealing it with tape temporarily might provide a short-term fix, but it is not a safe or reliable solution for a component as critical as the glad hand, which is essential for maintaining proper brake function. Replacing the glad hand ensures that the system operates correctly and safely.
