Same as you if you’re still in Northern Tassie, I got an old strut off you a couple of years ago.

Thought that might have been you. I can call around Friday after work, if you want to PM me. You got flare nut spanners?

Actually I have a Gregory's for a VS, swing by my work tomorrow or Friday and I'll lend it to you. If want to go with plan B let me know.

Thanks mate,it seems pretty straight forward,I’ve done it on other cars, I was just a bit worried about the ABS.Read a few things about air getting into it an bleeding it etc.Some say it can only be done on a specialised setup.

Point 3 in that extract is incorrect, no one proof read that one it seems.

New master cylinder, bled the system twice,new rear brake pads,did the lock up thing a few times on a gravel road to try and sort out the ABS, seemed to be better but not as good as I had expected.Brake pedal was reasonably firm. Go back out to the car an hour later and press brake pedal, still does the same thing , gradually loses resistance and depresses nearly to the floor.What else can it be?
