Ok Guys the jobs done.
Took all advise but had major problems. It was the accumulators; there was no sign of froth in the reservoir probably due to no nitrogen left in the accumulators. I got new ones but failed to get new nuts for them. Mistake number 1. Had the car up on stands not a lot of room and very hard to line up the hydraulics. Put the old nuts back on with a bit of loctite. These nuts are soft metal and are easley rounded off. But I thought it didn't matter, as it would be a long time till I had to get them off again. Mistake number 2.
Got the wife and 3 kids in the back for the 120kg's needed for the bleed and self reset. Started the car and watched the oil pour from underneath. Problem was a cross-threaded hydraulic nut I had been warned of and thought I had been careful enough to avoid. Put the car up on stands again and that's when I wish I had of replaced the accumulator 6mm nuts. I had to pull the accumulator back out because I couldn't get that hydraulic nut to line up without cleaning out the thread. Got two of the three nuts off, but it took hours to try to get the third off. I had to cut it of with die grinder, the only tool I had that could get into the space. A long and tedious job. Once I got the accumulator out I was able to clear the thread but had to get a new nut put on the hydraulic line by a local break specialist.
Needless to say a job that should've taken a couple of hours took all weekend.
I learnt a lot by this, and I guess that’s why we do it ourselves.
And the car drives like a dream again.
Thanks for your help guys.
