Can anyone give me a lowdown on brake fluid, please?
Got some DOT4 in atm, going to be swapping the lines over so will need to top it up anyway.
Do I want DOT4 or DOT5.1? (ruling out 3 as it's old and 5 as it's not compatible)
Any particular good brands?
Don't mind spending some £ for the "good stuff"
TBH I don't work the brakes hard, i.e. I don't think I've ever had the current fluid boil.
