Technical Brake Pipes

[RPeacock1986]

Good Morning,

I am currently working on a 98' Punto & would like some advice about the following :-

The rear brake pipe that runs into the rear brake cylinder has been cut (extremeley long story). I have some brake pipes that have been flared.
The male coupling on the end of the new brake pipe screws straight into the back of the rear wheel cylinder no problems.

The question I have is how do I connect the other end of the new brake pipe to the point where the original brake pipe has been cut. The new pipe (flared) has a male coupling.

I have attached a sketch (poor quality!) so that you have an idea of what I am talking about !!.

Any advice much appreciated, thanks

TBH I'd replace the whole pipe section and not try to join it.

Thanks Ffoxy, can appreciate thatb would probably be the best option.

Does anyone know the process of joining however ??

Thanks a lot

Female fitting on the blank end.

There is a tool which will flare the cut end to enable it to mate to a joint which has two female ends.
This is a very dubious repair and will be frowned at by subsequent mot testers although it technically should not fail if the braking is ok and there are no leaks.
I'm with Foxy on this one.....replace the complete line.......
It's so much nicer to be able to stop on demand lol

The existing pipe may be a lot harder than copper pipe
used as a replacement and trying to flare it may
break the flaring tool.

Absolute nonsense! As long as you make a proper flared joint on the original end it's a perfectly sound method. In fact it's exactly what FIAT have done - if you look just forward of the subframe by the centre tunnel you'll see male & female joints that make replacing the pipes much easier than having to replace the whole length of pipe. However this pipe probably runs from the backplate to the compensator so all the OP needs to do is measure the length of pipe needed from the wheel cylinder to the brake compensator & buy a pipe with two male ends to match that length. Motor factor will do one for under a fiver & away to go.

Exactly what I advised in Post 2 TBH...

As an ex class 4 tester myself you make your own brakes pipes at your peril.
