Thanks to all for the feedback and advice.

I will replace the front sections of pipe from the splitter mounted on the near side engine bay bulkhead to the mid section under the floorpan.

This way it keeps the joints to a minimum (one 2 way in the middle of each pipe) and dont have to disturb the rear pipes as they are fine

i wouldn't bother with a 6 in bit of pipe , but a hand flarer is handy for changing pipes such as on a mondeo where they can be perfect under the floor & rotten over the tank , replaced from the rear floor backover.

 You are going to all the bother splicing in a 6in section? Thats 4 flares! Two on steel and two on copper/kunifer.

Best practice and you know it makes sense, Replace it all.

i use a hand held flarer , perfect for flaring the steel pipes when they are in situ.

I'd have to agree, replace th whole line, flaring steel lines in situ can be hit and miss especially if you have a sykes and pickavant flaring tool that is supposed to be vice mounted :)

TBH if it was myself i would replace complete pipe saves having to repeat the process at a later date..some times steel pipes can be a begger to flare correctly so i would recomend a single flare..as long as there are no leaks..correct flare has been used..and rigid pipes are secure and not fouling then sir you would have a pass

I have an old Daewoo Nubira estate that has failed its MOT on excessive brake pipe corrosion where the front to rear brake pipes run under the front off side wheel arch.
The orignal pipes are steel with failed sections about 6" long on each pipe.

Can I splice in new copper/kunifer sections where the corrosion is without relacing the whole pipe run?
Or would I have to replace the whole pipe run to pass the MOT?

I will be using a flaring tool and correct connectors.

Also what is the best flare to use on 3/16 steel, single or double?
