hey just putting new axle on my b and having to do rear brake pipes as well with new hoses as old ones fell apart lol.. anyway my problem is at the box where the 4 brake pipes connect to at rear just above where beam is,, did the offside rear pipe with no problems... but then I made up new pipe and union nuts for nearside (passenger) then went to connect the union bolt into the threaded part on box and it seems the threads are much larger on the passenger side than the shorter pipe on drivers side.. anyone know what size it should be?? I assumed they would all be normal sized :/ ???? thanks

NON ABS model by the way

hey anyone with same problem its an m12 thread rather than the m10... just got it today and fits spot on..

It's so you can't get the pipes wrong
As the pipes have to be be in the right
Place with it being the break loads valve

thanks mate goinna be a long day on tools the morra lol. axle back on new brake pipes bleed system etc then on to my coupe to fit new flexi section lol.. one more qeustion will I have to bleed all four corners of car or can I get away with just bleeding the rear brakes.. as that is the only thing I have worked on. would save some time if I dont need to bleed fronts too and they prob seized up too:/

You can bleed just the rears as long as
You did not let all the fluid empty
But to be on the safe side I would bleed all
4 corners

thanks mate will check if the bleed nipples are easy enough to get off and poss just do whole system if they come free.. still plenty fluid left

In that case you might get away with just bleeding the rears
