Had a very similar thing on the way to Hyde one night. ( the night Barbara Acklin was on live )
The master cylinder on the Hilux had been dripping one drop of clutch fluid into the footwell every week for ages , I had a new one waiting in the glovebox but had not got round to changing it.
I was going cross country for a change , A1 , Newark , Mansfield etc , just got to the outskirts of Chesterfield when the pedal shot straight to the floor ..... Bugger ... guess I'll have to do that cylinder swap now ... easy enough task on the Hi-lux ...
Wasn't the master cylinder that gave out but the slave on the side of the gearbox .... !
So in the pitch black and pouring rain I just pressed on , the truck was very forgiving gearchange wise and I just got the timing right with no problems ( despite the fact that I was unknowingly trekking right through the Peak District ... had some wonderful views on the way back ) right up to the point when I had to stop at a long line of traffic at roadworks in New Mills , one thing she wouldn't do was go from a standing start with no clutch.
So I parked up in front of a line of cottages , knocked on the nearest door to let them know the story , told them I'd be back to collect it tomorrow and stuck my thumb out ...
Got to the nighter about an hour later , got sorted and off I went as usual , thankfully a very kind chap from Stockport ( Trev Dean ) gave me a lift to the Stockport Toyota dealership in the morning , they were open for some reason and after a lot of begging they went and collected the truck , towed it back to the workshop , fitted a repair kit for the slave , seals etc and sent me on my way. ( Told me the seal kit was a temporary fix but I ran another 90,000 miles on it )
As has said previously , sometimes common sense was left behind in the pursuit of a night out.
Thankfully a tad more sensible these days , but only a tad ...
