Hi all,
I have broken the brake line on my 86 jayco swan and was wondering if anyone knows the diameter of the copper pipe and the best way to go about fixing it??

Thanks
Dan

Should not be using copper pipe for brake lines, it work hardens and fractures.

Brake lines should be steel and double swaged.

The pipe should the the correct size for the fittings.

The best option if you do not have swaging gear and the knoweledge is to go to a brake shop or a good trailer parts suppler with the whole broken section of brake line and get em to make one up that matches ..... they will do all the bending too.

Gday
Its called Bundy tubing and is made of copper coated steel, the ends are to be double flaired. Copper pipe will make it unroadworthy.

What Bantam and Muzbry said is correct.
If you don't own a pipe double-flaring tool (they're expensive, I know, because I've got one), plus a small diameter pipe bender (got one of them, too) - take your old brake line to a clutch and brake place and they will knock up a replacement line for you, complete with new nuts and the correct bends in the right places.

Cheers, Ron.

HI
If its a minor rub thru or similar . U can clean with emery then white spirit. Wrap with filler wire and solder over the top .Rectify the cause
If anymore damage than above or if the lines are original replacement of all pipes & unions is best .
Highly likely there is corrosion on the inside of pipes/fittings
Take the pipe work off the van even if u have to cut off and take it to a good brake place and they will put all the major bends in the pipe .
Fit new pipe and flush and bleed

HI,
Typically done as temporary fix but it can be left if the remaining pipe is of course in good order .
A parallel fix to this is air brake line [flexible and rigid] repair or even diesel injector line repair .Both of these suffer rub thru and vibration cracking.
Also applies to the rigid pipe that has a new union or pipe section welded to it .
