It's the kids, stop driving so crazy!!! :lol:

HAve someone else drive and have them hit the brakes as they pass you in a parking lot or street. You stand outside and listen for which side.

How old are the rear pads? Maybe warning senor touching the rotor.

Suggested Repair

The rear brake-pad wear warning sensor was contacting the left rotor. Replace the worn rear brake pads (and service the rotors if scored) so the sensor no longer rubs.

Conversation Summary

A 1994 Mercury Sable with four-wheel disc brakes made a screeching noise from the rear when the brakes were applied. Advice was to have someone else brake while listening outside to identify the side, and to check rear pad age and whether a wear warning sensor was touching a rotor. The owner confirmed the noise was on the left and that the warning sensor was contacting the rotor.
