So I took my 2014 4Runner to service. I had front brake pads and rotors changed last year and had approximately 13K on them. They now said that I needed them again although 5K miles ago when I had oil change and tire rotation they said pads had medium wear and rotors fine. Also tires were fine. They also say I need 4 tires because they look "sawed up". After brakes and rotors changed still have jerking with braking. Any thoughts please
