My winter jobs aren't too demanding with my new to me 1957 Plus 4. It needs new brake linings on all 4 wheels (drums all round). There is a reasonably local company that relines brake shoes for a reasonable cost.
Whilst the wheels and drums are off, I need to investigate why the rear wheels are warm after a run. Note that the fronts are not. I am very gentle on the brakes, no sprited driving.
I will be replacing the engine and gearbox oil (I believe Redline MT-90 is best for the Moss box)
The tricky one will be getting the fuel gauge to work, the sender has a broken wire. I think I can sort it, but I am not as dexterous as I was

. Currently I have to use a calibrated dip stick to check the fuel level.
Other than those jobs, just a bit of tinkering when it's not too cold in the garage, and the odd run out if the weather is OK.
