nice one, I've been given links for the kits on e-bay, Astra Service Kit, which works out at £32.50 in p&p, and while I'm getting my hands mucky, I want to replace the front discs and pads as well, Astra G Discs and Pads which works out at £70, so all in all, £102.50 for a full service.
Does that seem like a reasonable price, as Halfords were selling the discs and pads for £50, and I don't need the air filter from the service kit, as I have a pipercross filter at the minute, so will just give that a clean and an oiling up.
