For the past few months, I've occasionally noticed a shudder from the steering column when I apply the brakes. It's not every time, typically when I'm coming to a red light after travelling 30-50 MPH. The shudder is quite audible, and the steering wheel moves around slightly.

It feels exactly like a brake pedal does when the brakes are warped. Only in the steering wheel

Interestingly, it always goes away if I briefly let off the brakes and re-apply them.

Any ideas?

Thanks!
