No. Bump stops are a rubber component located on the strut / shock shaft. They limit max. travel and provide cushion when the strut " bottoms ... " out over large sharp bumps. They will not create a shimmy or vibration under any condition. 99 % of the time a brake shimmy / shudder felt thru the steering wheel is caused by uneven pad deposits on the rotors, or uneven wear on the rotor caused by overheating. This can be caused by something as simple as coming to a firm stop from medium or high speeds, and then keeping your foot on the brake pedal for the minute or so the light is red. The pads are screaming hot, and now being pressed against one part of the rotor, super heating it, and the pads. New rotors will likely fix it, as would a light resurface / turning. Also, a change to a cheap metallic pad and some hard stops can scrub the rotors of any pad deposits. With almost all modern cars being automatics, it seems like brake shudder is inevitable at some point in the brakes life.
