hi when i was going over my 91 td jetta i notice a drastic difference in
the amount of wear of the rotors 1 was barely broken in and the other side was so bad it

Find a quiet street and cruise slowly. Take your hands off the steering wheel and apply the brakes. If your steering wheel turns when you do this, then one of your callipers is not functioning properly. Many things could cause this, most notably that when things get old they just don't work like they used to. Remanufactured callipers aren't expensive, so replace it, and you should do both sides.

If you aren't getting any pull in the wheel then it could be that the person before you just replaced one rotor, which isn't what I would do. Replace both rotors at the same time, same for pads. And if I'm replacing callipers I'll replace them both.

How is your brake fluid and do you know when it was last changed? Old fluid can gum up the works pretty good. If you want to see what kind of action you are getting you could remove the caliper and have an assistant gently pump the brakes. Gently though, you don't want to pop the pistons out of the caliper. What is the physical appearance of the caliper? Is it missing seals around the pistons? Is there evidence of leaks? Do the brake pads match from side to side (are they the same brand).

Regardless of the why, you most likely have a complete front brake job ahead of you. While you're in there, consider replacing the hoses that connect to the callipers as well. And while your doing that, check that the proportioning valve (located on the rear beam) is not seized. Bomb it with some sort of penetrating oil a few times and make sure it moves.
