Kinked Brake line
Hi Guys,
I have a kink in one of my copper brake lines which i need to sort.
This might be a stupid question, but can i cut out the kink (about 1" and simply replace with some tubing instead, e.g. rubber fuel line?
Regards.
Andy

Thought as much, is the only repair possible to replace the whole copper line then?

Yes, but if you have good flaring facilities it is possible to cut, flare and join in a new section of kunifer pipe. Many tin tops come from the
factory with joins just using male and female unions and flares.

This is your brakes! Replace the line is the safest option. Just my honest opinion, failing brakes ain't funny, ask me how I know.....
It looks like the Midget is winning at the moment......

If the car will likely have metric fittings on the brake plumbing, if that is the case you should try and keep all the fittings metric.
You will need an "on car" brake flairing tool this type works well and is a quality tool, which will produce decent flairs on the pipe
ends. In theory it makes old style SAE flairs but these work fine with meteric fittings.

You will also need
Male M10 fittings (sometimes called "tube nuts" and some "Kunifer" 3/16" pipe (nb. Kunifer pipe NOT copper
pipe)
Copper Nickel Kunifer Brake Pipe 25ft, 3/16"', 6 Metric Short Male Female Ends
Although not 100% essential a pipe cutter and pipe bender are useful.

You will need to do a few practice flairs before doing it for real as you will make rookie mistakes such as putting the threaded fitting on backwards
or for getting to put it on altogether.

I agree in an ideal world but I can think of at least one major luxury car manufacturer that mixes imperial and metric unions on the same brake line
albeit on one of their older models. IIRC it was a Silver Shadow by Rolls Royce. I also suspect that a lot of kit cars using bias bar master cylinders
may be using imperial fittings along with metric. It makes sense to check

Dammit lost my post.
Fuel line works under much lower pressures so dony even think it . Brake hoses like thosr going to front wheels are reinforced.
If access is easy repkave the entire line.
Otherwise use two jounets to fit a short length of pipe.
