1991 Mercury Capri Hand Brake Light Stays On

Hi Royster0922,

Thank you for the donation.

Have you checked the brake fluid level in the master cylinder reservoir?

If the level is low, the handbrake indicator light would stay on as they uses the same indicator.

Yes, the brake fluid reservoir level is fine.

There are no resetting available as problem seems to be a fault with the circuit being grounded somewhere.

At the reservoir, unplug the fluid leve indicator and test if the light goes away.

Is your vehicle equipped with ABS?

I unplugged wire connector to resevoir and noticed that the brake light turned off.
Brake light indicator came on like normal when handbrake was engaged and then turned off when handbrake was disengaged.
Brake light came back on when wire connector plugged back in.
The car is a 1991 and I believe there is no ABS.

If the fluid level is correct, then the fluid level indicator, at end of the wire that you unplug is bad or stuck.

Remove the master cylinder reservoir cover and check if anything is restricting the movement of the fluid level indicator.
