bad switch or possibly stuck switch
back up close to a door or building... press brake pedal... look into mirror to see if lts are lit
If the ((ABS)) Light is on then it's a good thing indicating that the Antilock brakes sensor is in good condition. I too have a 2002 mountaineer
check the brake light switch
On a 2002 Mercury Mountaineer : ( DOT 3 brake fluid meeting Ford specification ESA-M6C25-A ) According to the Owner Guide
According to the 2003 Mercury Mountaineer Owner Guide : ( DOT 3 brake fluid , meeting Ford specification ESA-M6C25-A )
DOT ( 3 ) brake fluid , if that is what you are asking ?
DOT 3 brake fluid
check brake fluid level.
It should have only a fuse and a switch, no relay. Check ALL of the fuses with a test light.
check the contacts on the brake light bulbs correspond with the terminals in the holder, eg not a single contact bulb in a double contact holder
In CT USA, a garage would charge 1 hour labor to replace the rear brake pads on that Mountaineer.
If the brake lights stay on that probably means the switch on the brake pedal that activates them is defective.
Go to dealer...and they will change them to early.
According to the 2000 Mercury Mountaineer Owner Guide : ( Yes , DOT 3 brake fluid , meeting Ford specification ESA-M6C25-A )

If locks have also stopped locking automatically, then you will have to change the brake switch located on the brake pedal. Go to a local auto shop and pick one up. It is easy to replace. Just look how the original is mounted, it is not too complicated.
Should be common to the brake light circuit
Disc brakes ( with small brake shoes in the back of the rotors for your parking / emergency brake )
"Stuck" brake lights indicate that the brake light switch on the brake pedal is broken. It should be replaced.
No , ABS is the anti-lock brake system
check fuses & brake lights switch located on brake pedal
I've had that happen on my 02 moutianeer. I got back in and hit the brake and it went out. You could have one of the sockets on your back lights burning out. THat includes the the top tail light also.
Your brake light switch under your pedal is brobaly stuck
The brake light is controlled by a little button switch that's mounted high on the brake pedal lever. If you follow the brake pedal upwards with your fingers, you'll feel the button. It has a spring in the button that pushes the button back out when you release the brake pedal. If the spring jams, the brake lights stay on. Replace the button switch.
