"Still grab", so this was a problem and you replaced pads and rotors because of this?
No, you wouldn't have front ABS in '94 and you would feel a pulsing in the brake pedal if it was.
It can be normal, try riding the brakes lightly for 100ft or so after starting out, see if they grab less.
New pads also need to be flattened out/rubbed against the rotors so they have equal(predictable) pressure on the surface of the rotor
Tires..........well my tires are not very good in cold or wet weather, they tend to lock up on wet crosswalk paint, lol
Forget snow
But locking up front brakes could be Master as well
Brakes work on fluid pressure, hydraulic pressure, this is used because it provides EQUAL pressure, if you put 20psi in you get 20psi out at the end of multiple lines, in this case 2
So no pulling to the left or right.
When you push down on the pedal the power booster adds assist to your pressure, if the Master piston is hesitant to move at first then releases you get Grabby brakes.
Your foot pressure goes from 5psi to 20psi instantly, but you should feel that, try riding the brakes lightly and stopping to feel if pressure is suddenly changing

Brake drums or rotors can flash rust in damp conditions. This can cause an initial increased friction and ease of lock up. I don't notice a problem with my front brake so much but the rear ones will lock up if I am not careful on the first few uses of the brakes. The front may be over-braking too but I don't notice it because they are more difficult to lock up. I just know my brakes work too well until that flash rust is worn off.
If yours continue to grab after a few uses of the brakes, it is probably something else causing the problem.
