Hello everyone,

I need some help from you guys...I recently had rear brake pads and rotors replaced on my 08 cobalt ss t/c...I noticed when the ebrake is applied the light does not show but when I start my car it flashes and it goes off. Even after it flashes and the ebrake is applied the light is not on. I also noticed while driving slow and coming to a complete stop the rear of my car has this crazy loud vibration sound when stopping...I am taking my car back when they are open but it's driving me nuts. Please someone help.
Thanks
