Adelaide is much cheaper for parts cos they are tight asses there
In Melbourne I would have thought a good front end would be worth 500 to 600 bucks with a booster in VIC, but when you say it is working fine, there is much more to it than just the brakes, How would you check the bushes etc, some roadworthy joints will get you just for rubbers and want king pins done mandatory. It's just getting ridiculous, its like they wanna see you spend some money just to make themselves feel better. This happened to me with a ford transit van with king pin front. They said it had wear and didnt even test it right (didnt jack up car, i think they wrote wrong things and shouldve been ball joints). So I polished up the ends and tarted it up with paint, then they passed it! This was a while ago and there was no wear in that area at all!
