"Chk Trac light" on 2000 Lincoln Town Car

read the 11th post about bad wires by muffler.

The simplest things can cause the most trouble - I would start with a load test on the battery - may seem to be charged after using a battery charger, but can have plate connection problems causing failure under load.

DID YOU HAVE BEFORE?DID YOU MOVE ANY WIRES?

remove the fuse either under the dash or under engine hood it will be labeled
Make sure thats the only thing that fuse is compatible to.

I had a very similar problem in my 93 town car. I ended up changing the Calipers, rotors, and pads. This stopped the grabbing, but still every once and a while the ABS light would come on and grip the brakes on me. I ended up pulling the ABS relay from under the hood.and the problem has stayed away. The only thing is that now i dont ABS brakes. Its a heavy car tho and i havent had an issue yet. Also, if you decide to do this, the relay way mis marked in my car, when i pulled the ABS relay, the Air shocks went out instead. Had to pull one at a time until the anti lock light came on, then i knew i had it.

An ABS Braking System problem,such as a
wheel speed sensor or other system fault

Need to have it fixed

telling me the trac light coming on could be a speed sensor problem, does your abs light come on as well? Does your speedometer, tachometer work good?

the abs light on the dash should come on when the abs is working (emergency braking)if it comes on when braking normally(gently)chances are a sensor is gone(replace in pairs,fronts & rears)
abs stops the wheels from locking up in an emergency brake situation,you will feel the grab-release,grab-release on the brake pedal......

this means one of the wheel sensors are probably bad, car needs to be scanned for ABS codes,get back to me with the codes and we'll go from there. most major parts stores will do this at no charge

sounds like the brake pads may be metal to metal, that could be the noise problem, but until u have the system tested for the trouble code that is setin the ABS modules memory when the light comes on you are guessing, the Dealer is the only one in most cases that has the scan tool to check ABS trouble codes.
