I have just been in the garage, I removed the clevis pin and loosened the nut behind the clevis pin quite a way back. I then reconnected the clevis pin (with ease - was much harder last time). I then finger tighten the nut up behind the clevis pin until it was just touching.
I tried the brakes, the travel in the pedal was much more (previously could be measured in millimetres). I pumped the brakes many times and it did not harden (like before). I may have cracked it.
As a brief test I asked my wife to press the pedal and I could not move the car (OK not great but the brakes are engaging and releasing).
I will take it for a drive later in the week and see how it goes.
Probably should check the brakes now to see if the shoes/pads are OK. Any guidance?
Thanks for all the input and help - a nice easy fix and an important lesson learnt!
