Ive got an 06 WRX with about 17,000 miles on it. Under medium to heavy braking a kind of vibration comes up through the wheel, I can also feel it in the brake pedal. It happens the most if the car is turning. This could be either while being driven hard or even on a normal road. It has happened for some time but now it is getting pretty annoying and I'm worried it will damage the car. Thoughts? Does $45 for a 30 minute check up sound ridiculous to anyone else?
