I'm not slagging all KF I'm sure there are some good ones but last time I went to get some new rubber on my company car (I have to use them) a guy was in with a Vectra in front of me for 4 new tyres and new front pads. He had the work done and left then came back in 2 mins later looking pretty angry. Seems they had changed the tyres and removed the old pads and left the new pads on the edge of the work bench. He said he'd just gone straight through a red light and just missed another car. I thought he was going to kill someone !
As MartinSSZ said have a read up and do it yourself it's very easy and you can save a fair bit of cash and know that it's been done right ?
