my 1970 V8 had a full brake overhaul 18months ago. This included reconditioned callipers all round, new pads all round, reconditioned servo and new brake master cylinder. I checked the operation of the foot and hand brake after this work and all was well, in fact in passed its MOT shortly after. Sadly, I've not used the car for around 12 months (handbrake off) and it was sat in my garage during that time. Upon returning it to the road I find that the NSR calliper is making zero effort with either the foot brake or handbrake although all other brake seem to be doing the right thing. Any thoughts?
