took the van for mot last week and it failed on front number plate tiny 2 inch hole in wheel arch and swollen brake pipe at rear ive sorted the number plate and welding i came to do the brake pipe i managed to get one from scrappy its a metal pipe that goes to the load apportion valve but could i ondo the bloody nuts could i bugger i have soaked them in wd40 for now has anyone got any ideas how to remove them im thinking of cutting the pipe near the nut so i could put a stud extractor over it maybe i have until tues before i have to have full test done again

have you tried a little heat via blowlamp-usually works on most siezed nut/bolts.

I've had to do just that in the past, if you have the complete section of replacement pipe with the nuts trapped on its length which lets face it, its not much use if it doesnt , then go for broke with a hacksaw. the bit your trying to save is the load valve and not the nuts !

Heat has been suggested which is always good and then whilst the nuts are hot a good dose of easing oil, but try not to heat the load valve as it may not do the internals any favours.

A small set of stillsons can be a blessing or a good pair of last resort grips can work wonders in these situations.

thanks for the replies i did try heat but didnt like doing it too much incase it did something else i have been dosing it up with wd40 since friday im going to havew a good go at it tomoz i will prop cut old pipe off as its no good anyway and have better access to the nuts i will post results tomorrow

Ive just had to replace this same pipe for the mot!
Came off ok with lots of wd40 left soaked over night.
I wouldnt recommend replacing the pipe with a second hand one; better to get your local motor factors to make you a new copper one; otherwise you might be doing the same job again in 12 months time!

I have a very small stillson adjustable wrench for brake pipes if needed, (Snap on ). John L.

sorted it i cut the pipe and managed to get socket on and i got them them off new pipe on and brakes bled ready for retest tomoz i put a second hand one on as there wasnt any rust on it and im getting rid of van within next couple of months and it only cost me a quid so couldnt leave it for that!!!cant moan at the van really its passed the last 3 first time for me and its just done 190k
