Brake drum relining in the UK revisited after testing
Posted: Thu Aug 08, 2024 10:58 am
After many years niggling at me I finally got to this project and back in March I posted about what I had done. In April the drums were fitted and have been on test since then.
In four months of lots of normal driving, around town, A roads and motorways I'm delighted to say they have come through with flying colours, performing brilliantly. I know from talking to the engineers, Lee and Roger, if they were going to be used for racing they have additional processes they have in mind.
I do have a few other things I would love to research, (idle hands!!), for example the best temp differential for the best interference fit and how to achieve these temperatures with simple/normal heating and cooling processes. I'm keeping an eye out for a few scrap drums to use in these experiments but as they are likely to be destroyed in the process they need to be scrap condition.
I have kicked around all sorts of fun ideas, a couple of the more extreme ideas;
Temperature controlled kilns set to 0.00015 C below when the ally is just about to turn into a blob, need to befriend a potter for that!
A bucket of liquid helium to cool the liner, a friend of mine uses liquid helium but didn't seem too keen when I suggested he brings some home for me to experiment with. What could possibly go wrong!
