Exhaust heat on rear brake line ?

[strictlypersonl]

My Q&D method: Slit some silicone tubing lengthwise, slip it over the steel lines, and secure with metal ties or stainless steel wire if necessary. The latter might not even be required with the heavier (1/8") wall stuff. Just harder to put on.
McMaster: silicone tubing

Caveat... The covering may encourage the tubing to rust over the long term.

Thanks for the ideas and links. The split silicone tubing may be the easiest since there are one or two tube mounting clips up there above the muffler and I don't know if I can get to them without completely removing the muffler and tailpipe on that sid - a step backwards I would like to avoid.
