Shaky Steering Wheel and E-Brake Light Issues Options

[jds7188]

ive been having this shaky steering wheel problem for a while now. Everytime im at a speed, lets say 40mph+, and i hit the breaks to slow down, my steering wheel gets very very shaky. is this normal or does nobody else experience this? i figured it could possibly be an issue with my rotors being warped or something to that extent. other than that, i have no clue.

also, my e-brake light has been going on and off for quite a while now. it will stay off for a little bit, but after i speed up , it turns back on, then it stays on for a while. and no, my e-brake is not up.

if anyone could help me out with either of these problems, it would be greatly appreciated.
