New pads, weak ebrake?

[THEMkris]

okay so i just got done installing new hawk hps on my s14. had to replace the rear rotors in the process. i worn in the breaks for a good hour or so as well. but still the ebrake is not catching nor locking up the rear wheels. what could be wrong?

**EDIT**


i need to pin down the problem..

1. brakes have a lil "drag" (hear brakes dragging on rotor)
2. stepping on brake or pulling ebrake makes sound louder.
3. ebrake is weak. does not lock wheels at all.
4. piston on rear caliper is ripped. no leaks.
5. improper wear on brakes (not fully using entire brake pad surface)

what can be my problems?

the only thing i can think of is that my piston is bad. the caliper isnt retracting all the way, isnt pressing the brake pad sufficiently, and pushing in the brake pad crookedly.

any other reasons that i should keep in mind?
