Hi guy . Does anyone know the average mileage you will get from a set of front discs. Had my car serviced at Lexus Chester in august last year . 17000 miles at time . But came back as a advisory that front discs had a lip on and 3 mm on pads . So I've got new brembo front discs and pads for less then £300 from euro car parts £80 fitted from a good friend that's a mechanic. How much would Lexus charge me ?
