I have just pulled apart 3 old brake regulators to clean them up for storage and there are 2 different spring lengths.
I think that the cooper s had a different spring in it due to the disk front end but not sure which spring it is.
One spring has 9 winds and is 32mm long and the other has 10 winds and is 36mm long.
Anyone know which is which?
