$3,000 for a brake repair?...you must have let it grind down on the rotors
Brake linings cost about $80
And Y-Tube videos show how to do it.
Just a thin 17mm wrench...and an adaptor to reset the back brake mechanism.
I get 50 MPG steady in my 2014 Prius (now at 200,000 miles) steady as a rock driving a thousand miles a week for Uber
Trick is to use ECO and BRAKE (B) mode..reduces wear on front brakes.
PS... only replaced the front and rear brake pads and spark plugs only once ...and did the job myself.
