Took the car to the garage to get new rear discs and pads fitted by the professionals(tried to budge the stupid spline bolts to no avail - with the correct tools i may add), plus get a diagnostic done to try and work out the odd hesistation the car has.
Then came the dreaded call to say that the calipers had ceased and even after much effort they would not budge - £131 each side - could calipers be any more expensive - just the standard GTI ones too
Still at least they will look red and shiney brand new to match the new discs i guess
