Hydraulic Warning Light

Brakes

Description

Located on the instrument panel, this warning light is usually red and labelled BRAKE. The light glows with the ignition switch in the on position.

Purpose

The hydraulic warning light glows when there is a loss of pressure detected in the hydraulic system. On some cars, this light may be used to alert the driver that the brake fluid level is low.

Maintenance Tips/Suggestions

If your car’s BRAKE warning light comes on, check your owner’s manual to find out its meaning. Unlike some warning lights, the BRAKE warning light does not have standard meanings; it may be also be used for multiple purposes. For example, the same light may be used to show that the parking brake is engaged and when the fluid in the master cylinder is low. When in doubt, have the condition checked by a qualified service technician right away. A loss of hydraulic pressure can affect brake operation, which can make your car unsafe.
