There are many reasons why the steering wheel will shake when stepping on the brakes. It is best to find a professional and technical person to check this problem. Possible causes include brake system problems, brake pad/disc wear, harmful liquid leakage, loose steering wheel bolts, faulty or bent parts and other factors. If you don't want to try to repair the car yourself, I suggest that you take the car to the local garage and let an experienced technician check and repair it.
