Brakes

[mark]

Im new to making brake lines so any advice will be greatly welcomed

Ive done a few running repairs making the odd brake line over the years on daily drivers but just dusted off my flaring kit and read the instructions. It illustrated a female flare, a male single flare and a male double flare, when and why do you use different types of male flare?

Also my hydraulic brake light switch from a vw caddy seems to be flat on the end of the male thread, what kind of fitting do i use when i install this switch. I assumed it would just fit in the t piece.

I probably know enough to have got my way through this job but i thought i would ask on here as people who have lots of experience will probably make lots of usefull suggestions and make my life alot simpler this wk end when i start on them

Simple Mark,male flare into union's ie: brake hoses cylinders etc,male and female to join pipes. Just like pro-creation the male fits in the female......
If the contact surface inside a join/union is raised it needs a female/double flare.

Thanks, it was just the double flare thing thet confused me mainly i always just thought male, female and that was it and hadnt heard of a double flare.

Do you have any advice about the brake light switch? if it has a flat bottom on the thread will it seal when screwed into a tee piece?

If it's a metric one, it's usually a taper thread, so a bit of PTFE tape should seal it ok (That's what Car Builder Solutions say anyway!)

Yeah now you mention it when you screw it in by hand it only goes in halfway then becomes tight almost as if the thread is tapered

Thanks for the tip

If it's tapered as Adrian says a bit of PTFE tape,if not a small copper washer on it.
