The CHMSL (center high mounted stop light) is activated by a circuit independent of the outboard stop/turn lamps. Outboard stop lamps become left or right turn signals when interupted by the turn signal switch/flasher circuit. The CHMSL must remain independent to escape the interuption of the turn flasher. The circuit that powers the outboard stop/turn lamps and the CHSML share the same fuse on GM, Ford and others are probably the same. The 12v feed passes through the brake light switch before it splits to independent feeds: one straight to the CHMSL, the other to the turn switch/flasher which splits it into a separate feed for either the left or right lamps. My best guess is your OK at least to the brake switch. The problem lies beyond and my experience would lead my initial search for a faulty ground in the rear lamp harness. Good luck, it's a cold day for working on a car.
look at the level in the master cylinder near the firewall.
Low brake fluid level - due to leak or worn brake pads Parking brake not fully released
If you are speaking of the low level brake lights - open the hatch which will expose the screws holding the taillight housing in place. Remove the screws and carefully remove the entire housing exposing the wires and socket on the backside. Carefully un-twist the socket and carefully remove the bulb and replace in reverse order.
more often than not there are three brake lights. one at eye level on the rear windscreen and one either side of the hatch/boot. Hope this helps

This can be two reasons for this....(1) is that your emergency brake is not fully OFF or (2), your brake fluid is past the LOW level in your brake fluid container in the engine....just add more brake fluid to top it up to FULL level and the brake light will go off.
Yes , the " BRAKE " light in your dash lights up if the emergency / parking brake is on or if the brake fluid level is LOW in the brake master cylinder in the engine compartment
Sounds like you have a problem with your brake light switch under the dash, mounted on your brake pedal metal arm assembly. I know if I get my head down near the brake pedal and push the pedal with my hand I can hear a loud click noise when the brake lights come on. I'm not a mechanic, but I've wondered if the brake fluid level is down in the master cylinder, does the brake pedal drop enough for the brake light switch to turn on the brake lights ?
I'm not a mechanic but I would start by checking the brake fluid level in the brake master cylinder in your engine compartment
this happened to me on my 98 Honda accord and it was because my brake lights and sinal lights were not working properlyMost likely, the brake light switch is stuck. Have you checked your brake fluid level? You could be dangerously low.If you mean that your exterior brake lights stay on even when you aren't pressing on the brake pedal, you most likely have a bad brake light switch.If you follow your brake pedal arm up under the dash, you should see a switch that comes in contact with the arm. It might have been knocked out of position and all you need to do is put it back. If it is in its correct position, it is probably bad and will need to be replaced.It works like this...when you press on the brake pedal, the arm moves away from the switch, thus turning on your brake lights. When you release your foot from the brake pedal, it contacts the switch and your brake lights turn off.
Check the brake fluid level. If it is ok, take it to a garage that can diagnoise ABS problems.
Start with checking the brake fluid level in the master cylinder reservoir. If it is low for whatever reason, those lights will come on.
