The leather cup valve in my bicycle pump broke. I can't get any build up in air pressure while trying to pump my tyre. This comes as no surprise as this pump is something like 30 years old maybe more.
I tried a quick fix by supporting the broken part of the leather cup with a piece of flimsy plastic. It worked for a while, but then there was a 'pop' and the leather cup is now in worse shape than before. A bigger tear now. Needless to say, it is now beyond repair. I was obviously disappointed.
I tried a couple of things as a fix but the cap of an old 35mm film canister, that has been lying around the house for years, did the job for me in the end, believe it or not.
