I had put a cam in months ago and then I put some of those crossed drilled and slotted rotors on and now my brakes dont seem to work to well at idle im wondering if I should do a vacum can or pump what do you guys think?

thanks and the cam is MTI T1

 

The vacuum can wont hurt and i think ive seen them for as little as 40 dollars, though i could be wrong.
