[ROVERNET - UK] Brake flares and fittings

[Warwick Brooks]

Also remember that these tools are generally designed for thin-wall steel
Bundy tubing and not copper.  If you attempt to use them to make a double
flare on copper tube for perhaps a short section of clutch line for example,
you can damage the tool if you don't re-anneal the first flare before
attempting the second.  The thicker (usually) copper that has been hardened
by the first operation puts a lot of stress on the die.

Warwick.
