will bleeding my brakes help my ebrake grab better at all? or is it possible that my cable is streched...? like the cable doesnt feel streched, but i have to literally rip the fuck out of the brake for it to actually lock, or else it just slows the car down. the reason i ask is because i figure it being mechanical, that the fluid has nothing to do with it, but i may be very wrong. and i just replaced the rear pads and rotors, so thats def not the problem.
