Hi Guys
I want to replace the flexi brake hoses on the back of my Polo breadvan with a set of braided stainless,
The problem i have is the ends seem seized onto the end of the copper brake pipes has anyone got any tips for removing them without destroying the copper pipes as they are in good condition and run from front to back of the car so i would rather not replace them
Cheers Adrian

Heat, penetrating fluid and proper brake pipe spanners. Also remember that you wind the union on the solid pipe not the one on the flexi. Seen people try to undo them who don't realise that and end up with candy cane brake pipe.

lots of soaking in plusgas or similar or If it really wont budge there might be another slack pipe to cut if close to the union and reflare it.

As above. Some great advice present here.
One more thing however, is that I would use brake pipe spanners. With these I have far less situations where the unions become rounded or (with a combination of them used) the hard pipe requires remaking.
Another thing is if you are going for braided lines I would look at the HEL brake lines. Their unions are great for working with awkward pipes (the unions on the flexi sections spin around and not fixed like other derivatives (stock or Goodridge etc.).

Beware if you are heating brake fittings, Brake fluid is imflammable and burns very well.

I once heated a caliper up to free a stuck bleed nipple, and the fluid inside boiled causing the flexy hose to explode right in my face, covering me in boiling brake fluid. That was very unpleasant. It wouldn't put me off using heat (it's sometimes your only option) but I'm just more careful about it now.

I use GT85 but there are lots out there to use, then i soak a rag in ATF and wrap the joint in it overnight, next day work the nut a bit at a time to clean the thread, undo 1/2 turn do up 1/4 turn ect ect and as said, brake spanners are bloody great compaired to normal spanners

I found on my polo the unions were so seized onto the steel pipes that it was easier to just replace them with copper pipe. A little copper grease on the bit of pipe under the union stops it happening in future too.

I broke mine and had to go to half fords at 7.30 at night and pay top dollar for a brake flaring tool. Best thing is to order some unions and the tool before you start. That way, if you are not bothered if they snap then they won't. They only snap when you don't want them too!

Soak them over night.cut the pipes and get a good socket on rather than spanners
