Hi all, I have been told I need a front disc and pad change as a result of my last service on my 2017 is300h. They have given me a quote of £520. I know that I can buy the parts and do it myself if they are traditional wheel off, calliper off, screw out, disc replace and calliper back on with new pads in. Is it going to be this way or is there something weird about this that needs £520 Lexus to do. TIA.
