Hi All,

Was hoping someone may be able to share some advice on this - has anyone had trouble removing the brake lines form the actual bottom of the mastercylinder.

The nuts are VERY soft and just seem to turn into putty even with the correct sized spanner on them? Why i actually want to take them off is that i've managed to find a sunny brake booster and am hoping to put this on (all looks pretty straight foward)

Any thoughts on this would be good!

Cheers,

sunny booster aint that straightforward... gotta file the hole quite a bit bigger then drill four new holes in the right spot. the rod to go to the pedal then needs to be modified. its not rocket science but its a lot of farting around.

on the nut side of things you can buy specific 10mm spanners that are just short of being ring spanners. if the nuts are already threaded you'll have to resort to vice grips or multi grips.

good luck

the trouble with the brakelines could be 2 things.nissan seems to use a locking compound on them from new,so if its the first time undone,it's a pain.also,with brake lines,the technique is to shock the nut,not torque it.so,try a little wd40 or CRC spray,get the correct flare spanner,which is like a ring spanner with a segment missing,then shock the nut by a sudden application of force.remember,lefty loosy,righty tighty.if you dont get it to let go,try some more wd40,then try hitting the
flare spanner with a small hammer,like a tack hammer.if you try to torque the nut,it'll round the shoulders,& wont be reuseable.but,seeing as you're putting a booster on, the lines aren't really usable anyway.get a small set of vise grips
instead of the flare spanner,& try the shock technique.it doesn't seem to make sense that
this is necessary,but believe me,it is.

Yeah agreed.

Pipe spanner is what your after.

Single hex ring spanner with a small section missing to fit it over the pipe. Will work a treat.

Vice Grips!

They put some marks on the flats, but in almost all cases it gets them loose.

I don't know of any of these other tools, so it's good to learn about them.
