I need to replace a couple of brake pipes at the rear. I was going to by a kit - but what size pipe and fittings do I need please?
Thanks

4.75mm pipe and M10 fittings. If you don't get them as a ready made kit then make sure you do the correct flare and do the job right and get cupro/nickel (Kunifer) not copper

In real money its 3/16 inch tube, as advised definitely buy cupro/nickel tube
