My mate works at a garage and as a 'foreigner' was going to change my rear discs and pads, the fool only ordered the wrong pads, but insists he didnt. He said there is a clip missing off the set he bought. My vectra is a 1.8 2004 SRI with the standard alloys. Is there a variety of pads available? Help wanted I have an MOT friday and my brakes are no good at all.
