I have just had a call, Its not the cyinder after all He said that somone on the last service (NISSAN) main stealers had adjusted the handbrake wrong so he had to apply more pressure on pedel than normal to get the rear shoes to open fully on the drum. So he ajusted the handbrake the right way and the rear brakes are now doing what they should.
You can`t beat a local village garage, honest, reliable, and half the price of nissan and with more knolage than nissan. ÂŁ95 MOT, Labour, :dance:
