Lorry sulphur smell

[Lightning]

On using the lorry today, we have smelt sulphur in the cab. Can we still drive this tomorrow to a local show?
There was a hissing sound from the handbrake also when getting the air breaks up, but this stopped after wiggling a wire . Could they be connected?
Help !!!

Sulphur smell is often battery or wiring, please please get everything checked for safety.
It can also come from old diesel, but I'd def get checked through.

Don’t drive it until it’s been checked by a mechanic.

Definitely do not move it until it has been checked. Most likely to be batteries, but they may not be the root cause.

It could be a number of things including the brakes binding. Do not use it at all as it could cause the lorry to set alight. Get it checked by a compenant lorry mechanic.
