Ok I've been noticing for a while now that whenever I have the brakes applied and go over a bump it feeling like something is loose. I'll feel a slight pop in the brake pedal especially if I'm turning right and am on the brake pedal. Also I can sit still and have the brakes applied and turning the steering wheel back and forth slightly and I also feel it in the pedal. It hasn't really gotten any worse and I would say the average joe wouldn't notice it. I looked under the dash and the only thing I see attached to the pedal is the steering shaft. Any ideas?
