BRAKE ALERTS<br />
Brakes are responsible <strong>for</strong> a majority of the alerts issued by SIRIS (this could vary by<br />
site and environment) and are an important safety issue <strong>for</strong> trucks, buses and other<br />
large vehicles.<br />
When a vehicle passes through the system, SIRIS measures the temperature of the<br />
brakes through the rim. The brakes are compared to the criteria set <strong>for</strong> SIRIS and an<br />
alert can be issued <strong>for</strong> a hot or cold brake.<br />
Hot brakes can be caused by many different circumstances including but not limited<br />
to dragging brake components, air system defects, mechanical errors, failure of<br />
opposite brake, or driving preference. Cold brakes can also be caused by some of the<br />
same conditions including but not limited to suspension, mechanical or air supply<br />
issues; inoperative or out of adjustment; or incorrect or missing attachments.<br />
When a brake alert is issued, the operator should view the screen and the temperature<br />
data <strong>for</strong> the brakes. (S)He should view not only the brake temperature <strong>for</strong> the side that<br />
has been flagged but the in<strong>for</strong>mation <strong>for</strong> the brake on the opposite side of that axle. A<br />
brake on one side could be hotter due to an inoperative or faulty brake on the other<br />
side.<br />
