Rear brake pipe union wont undo!

Am in the process of replacing the upper suspension arms on the D3.

After lots of swearing I’ve managed to get 2 of the bolts off. I’m now at the point I am ready to undo the brake line.

My 10mm spanner is too big and is spinning (it doesn’t seem rounded) and the 9mm won’t go on. Am I missing something??

Just double checked , Pipe in the middle of the hoses is 11mm

Also the bleed nipple and top nut is 11mm , also find using a brake pipe spanner helps where the nuts have been round off before

Weird as I’ve just put a spanner on the fittings and there 11mm , might have to use some mole grips if u can’t get a spanner to fit or rounded

Don’t forget plenty here to always help if u get stuck

Hope that helps

Hi

That’s weird its a different size, i also cut the very top nut off the copper pipe and put a new flare on it as the copper pipe was just twisting

Have u tried a 3/8 spanner as that just under 10mm
