For the car with such age it can be anything. I would start from main brake lines. If the lines are fine, check calipers and rear brake cylinders for leaks. If you find any leak it's easier to replace a part, then trying to fix it.
A Toyota Camry built in 1998 takes DOT 3 brake fluid. This is the standard brake fluid for passenger cars.

It means that your parking brake is on. :-) Or there is a problem with the brake system, as in low brake fluid.
Check the brake fluid reservoir. If it is low, the light will come on notifying you that the brakes need to be serviced.
If it only flickers it may be due to low fluid level in the master cylinder. Check your brake fluid reservoir.
There is a switch above the steering column (underneath the dash) that may need to be replaced. This is not visible from below the steering column. Good luck.AnswerIt is more likely that your brake fluid is a little low. Top it off and see if the light goes out.

The red brake light indicates that the parking brake is on or that the brake fluid is low. Be sure to add the specified brake fluid if you add fluid. Also make sure that you don't allow any dirt to get into the brake fluid and don't overfill the brake fluid either.
