A couple of days ago my front end started shaking a bit..(and I'd just recently installed new Conti DWS tires and a dealer alignment). Then I could smell a burning odour. Looking at my driver's side front wheel, I see its caked in brake dust. Now I'm assuming I have a stuck caliper. Brakes (pads) were done about 5kms back. Is a stuck caliper a simple fix ?? What am I looking as far as mechanicals are ?
