Very carefully
You have to change the whole rearend and the master cylinder.
Take off the tire, remove the brake caliper, and pull off the rotor.
The minimum thickness for a 1998 Chevy Tahoe's rotors is 30mm. Rotors must be replace when they fall below this thickness due to reduced braking power.
Yes, it should be disc brakes.
We have a video that I'll include a link to below that will show you how to do the rear brakes on a 92-99 Chevy Tahoe.

When you open the liftgate there are two screws inside which hold the taillight housing in place. Rotate the housing out of the fender and the lamp sockets will then be accessible.
The front rotors for a Chevrolet Tahoe typically measure 12.8 inches in diameter for most models, including those from recent generations. However, this size can vary slightly depending on the specific model year and trim level. It's always best to check the owner's manual or consult with a dealer for the exact specifications for a particular Tahoe.
