So off we went, had our breakfast in the thatched bakery in Aberdaron which is excellent if you ever get the chance.
When we got back out the blue 1VJ wouldn't start and the front brake caliper had seized on.
We checked the wiring and found the main light was causing a large voltage drop, easily found as this bike has a digital dash with voltage reading. We checked for anything obvious on the caliper but eventually took it off and didn't really find anything. When we put it back together it seemed ok so carried on.
By Pwllheli it was back causing issues and we nearly went back to get another bike, but decided to carry on.
Aberyswyth on the front.

Aberyswyth is bike friendly and has a great free parking area on the front.
We then turned inland for Tregaron and went up and over the devils staircase, what a road, absolutely perfect for the Tenere's.
No photos sorry we were enjoying it too much.
But on the way down the 1VJ front caliper problem reappeared and was basically seized by Llandovery. We stripped the pads out on the side of the road and turned up at JE Rees agricultural machinery dealers in Llandovery right at closing time. We stripped the caliper and blew the piston out using the air line. We couldn't remove the master cylinder screws so Geraint put us in touch with a Quad bike dealer who had a master cylinder off a Honda quad we could use.
A fairly steady run over to Llandeilo without a front brake, found us outside the dealership. An extremely helpful man drilled the master cylinder screws out with a left hand drill. One broke and one came out perfectly, we'd cleaned the piston and caliper with brake cleaner having found some grit in the caliper which was probably enough to stop the piston travelling freely.
We then removed the stub left in master cylinder and bled the system, extremely thankful to the quad bike man.
We then travelled straight down to Tenby on dual carriageway as we were late for check in. Brake working perfectly.
End mileage Friday

406 miles on the first day, fair peddling on 40 year old bikes.
