Default copper pipe for brakes

hey guys

so ive had my jeep for 3 years now and i love it so i want to keep it running sweet, i had new discs and pads around 18 months ago and i asked them to change the fluid but they couldnt as the bleed nipples were seized.
i would really like to get this resolved as my fluid is jet black so its well past its best.
i am awaiting a price on the following from jeep

-brake pipes all round
-brake calipers all round
-brake hoses all round

i reckon its going to be eye watering and as the car only cost me £1500 3 years ago i dont wanna spend much on it, ive heard about peple making brake pipes from copper, is that a done thing as i would have thought copper would be too soft.
i wonder if godspeed could help in regards to rebuilding the calipers if needed to save buying new

use copper nickel it lasts a lot longer , companies can do it for you but if you are handy with a spanner plus have the right tools it’s not that difficult to do

I think the best stuff is called cunifer, it's a mix of copper (Cu), nickel (Ni ) and ferrous (fe) hence the name.
Copper brake lines are illegal in US 'cos the bending process makes' em brittle and prone to fracturing. But over here GB anything goes, and I thing garages prefer copper as its much softer and easier to work with and form. Halfords only sell copper, but cunifer IS available from some motor factors,

thanks for the advice guys i will ring around, to be fair the pipes may be overkill as they come up on the advisory as being covered in grease so just getting prepared just incase.
the calipers will be the issue as the nipples are seized.

thanks again

You need a braising torch not burning gear and just go round and round the nipple.

None of that list is very difficult to DIY. It is probably overkill to do every hard brake line on the car- I'd just give it a good check over and replace any that are badly corroded as and when they need doing.

It is the labour that will make it very expensive, although it will also depend on what prices your mechanic gets for callipers. From ECP or similar exchange refurbished ones are normally £90-110each. Are all callipers stuck? Often they benefit from a good cleaning out and regreasing if they're not seized. Physically swapping callipers is pretty much a bolt-on, bolt-off job.

You can buy rolls of kunifer brake pipe on ebay/online and it isn't really that expensive- it is a little harder to work with DIY but still not too bad.

If you don't need to buy any callipers and just one brake line is corroded that's more like a £90 bill than a £1500 bill so I'd caution against replacing everything just for the sake of it!

More reliable than a Subaru? Owned Subarus for years and only had to replace odd wheel bearing.
