Brake Light Question

[rezeeb]

Obviously, the brake light is illuminated when the parking brake is on, but why else does it come on? Recently, the light has come on while I was braking. Does anyone have an idea what this means? Thanks

Check your brake fluid level. The brake light also serves as a LOW FLUID warning light.

If your fluid is low, i bet your pads are worn down and almost ready to be changed.

Brake fluid never evaporates. So unless there is a leak, low fluid always means time to go get a brake job.
