Next day had a look to find that outer brake pad was completely without friction material just the metal backing plate. The inner pad was about a third worn. Pad wear indicator not connected. Fortunately disc has not badly marked. I fitted new pad and road tested OK.
I remember when I last changed the pads that outer ones were much more worn than the inners. Is that common? Calipers are free to move and parking brake is fine. When rain stops I will check nearside and expect to change outer pad aswell.
Don't know if it is related but both front tyres have worn bald on outer inch of tyre.
Luckily I have sourced 2 as new Michelins on French ebay for 50 euros just 10 kms from my house.
Regards and happy if damp Guy Fawkes.
