As above realy, is the Lucas Girling stuff from my local factors ok? Its dot 4 or 5, Or, do i need somthing more exotic for AP brakes? Dont want to bugger up any seals

Prodrive Andy

for ap brakes u need dot 5.1.

Thanks for that Andy, i reckon the Lucas Girling dot 5.1 will be ok then??

You don't need to use anything in particular (except to avoid using the Dot 5 silicon fluids). Dot 4 will be OK with AP seals as will Dot 5.1. But Dot 5.1 is a better fluid than dot 4 so if you have gone to the expense of decent brakes it would be a bit daft to use cheapo brake fluid.

stockcar

not strictly true, Dot5.1 is commonly mis-sold/ supplied as a "performance" fluid and does not apply across all makes!!!........to be exact SOME Dot5.1 fluids are better than SOME dot4's, however, a lot of "race" fluid are ONLY dot4 (and sometimes not approved at all!!!) and yet wil outperform the 5.1's......
the "dot" rating is a measure more of how hydroscopic (how well it repels mosture) the fluid is, this is why certain "racing" fluids are not "dot" rated (and not really suitable for a daily driver) as the attract moisture too readily......the temperature ability of th fluid is more pertinent and should be stated on the tin!!
hope this helps

p.s. the quote is correct about most fluid's being suitable.....
