So after much fuckery in the cold and head scratching the fault with the C8 OS binding brake was eventually traced ( after replacing all three handbrake cables twice because it only ever happened when the handbrake cable was applied).
Turned out that the new caliper was faulty. What is the chance of that happening ?
Wouldn't happen every time, 9 times out of 10 when released the caliper released OK and on the 10th time it stuck on about quarter of an inch.
Caliper exchanged with ECP who were not cnutish about it in the slightest and so far all appears well.
Then... The Almera, the zorst ( which had previously been blowing from the mid section and responded well to some sparkly stick action) decided to do an impression of a V8. That I could put up with but the clonking, not. Took it to National today as they were the only place open near me and after a wait of an ice age was told they had to replace the WHOLE zorst front to back at a cost of over £300. Now bear in mind the car isnt worth more than that after the escapade with the old lady and the street vandals of Fulwood I was a bit loath to pay that.
So, now, from Preston, its the Bodge of the week....
Chufty award for correct identification of all the cables used....
