The brake lights on a 1993 Topaz are typically controlled by the fuse labeled "STOP" in the fuse box. The fuse box is usually located under the dashboard or in the engine compartment. If the fuse is intact and the brake lights still do not work, you may need to check the brake light switch and bulbs.

If you are replacing the brake lines ( metal ) then just use your better judgment. They do not have to follow the original route.
To replace the rear brakes on a 1993 Mercury Topaz, start by safely lifting the vehicle and removing the rear wheels. Next, remove the brake caliper by unbolting it from the bracket, then slide it off the brake rotor. Replace the brake pads, ensuring to compress the caliper piston if you're installing thicker pads, then reassemble the caliper and reinstall the wheels. Finally, pump the brake pedal to ensure proper brake function before driving.
