reb78 Posted February 15, 2021 Share Posted February 15, 2021 Can you folks help me create a list of the various bits I need to put together a box of bits for making brake lines for my 1989 110? Copper brake pipe and male and female unions I guess? But I dont know what sizes/threads/bore I need for the various bits and am unsure of where to look.

western Posted February 15, 2021 Share Posted February 15, 2021 M10 x1.0mm pitch for the end fittings. male & female, I think one of the master cylinder ports is bigger [it may even be imperial] use Kunifer [90% copper/10% nickel] brake pipe 3/16ths Copper brake pipes hardens with age & can fracture. https://automec.co.uk/collections/fittings https://automec.co.uk/collections/brake-pipe-coils Quote Link to comment Share on other sites More sharing options...
cackshifter Posted February 16, 2021 Share Posted February 16, 2021 I would also suggest if using Kunifer (great stuff) or copper you don't use the normal zinc plated steel unions - they last about a month. Automec, VWP, and Frosts, maybe others, sell brass ones which seem more resistant to corrosion, also brass bleed nipples, and Automec at least do the spring washers to hold the flexible pipes. Automec also do the plastic chassis clips for the pipes, in fact they will do you a nice kit of ready made Kunifer pipes Quote Link to comment Share on other sites More sharing options...
reb78 Posted February 16, 2021 Author Share Posted February 16, 2021 Thanks Chaps. So some silly questions. Whats the difference between these types of fittings - https://automec.co.uk/collections/fittings/products/brass-brake-pipe-fittings-metric?variant=12986154942487 and this https://automec.co.uk/collections/fittings/products/brass-brake-pipe-fittings-metric?variant=12986154876951 - obviously I can see the thread difference but when would you use one compared to the other? And is this https://www.advancedfactors.co.uk/31187--brake-pipe-nut-m10-x-1mm-short-female-pack-of-50-1240498-p.asp the same as this https://automec.co.uk/collections/fittings/products/brass-brake-pipe-fittings-metric?variant=12986154909719 but just a different shape and brass?

oneandtwo Posted February 16, 2021 Share Posted February 16, 2021 As I live by the sea, I have taken to wrapping the steel unions in small slices of Denso tape, which has prevented any rust occurring and has been well worth the time spent doing it when I have had to undo them years later. 1 Quote Link to comment Share on other sites More sharing options...
