Re: How do I Keep my brake lines cool ?
 

Yes what L.W. said, use sheet metal or I have even seen reflective material
that is very flexible used too to protect either fuel lines or brake lines.
Is there enough air moving that heat out of the brake line area? Maybe you
might want to think about that too or rerouting the brake lines away from
the heat! :-)

DO NOT USED DOT5!!
AFAIK That would require renewing everything in your system due to a
chemical interaction with the "stock" fluid. DOT 5 is supposedly great for
cars you store for many years, but not the greatest for your daily ride. I
even think it is illegal in some racing vehicles and I think their brakes
get very very hot!
Definitely use a quality DOT 4 and flush well! I think Castrol might be a
good brand to use.

Re: How do I Keep my brake lines cool ?
 

Actually, there is no chemical interaction, they won't intermix at all.
Changing to DOT 5 properly requires a complete overhaul of the brake
hydraulic system and flushing the lines with alcohol, MEK etc. Merely
flushing the system out with 5 will leave small pockets of the original DOT
3-4 which hold moisture and corrode.
DOT 5 conversion eliminates the cause of most Hydraulic failures, corrosion
pitting in the bores. I run it in my vehicles, and in all that I have
restored that use hydraulic brakes. Like any other brake fluid, it should be
flushed annually, or more often if you play in a lot of mud or water. It
seems perfect for a vehicle that crosses creeks. DOT 5 was formulated
specifically for racing and extreme temperatures.

How many drivers flush their brake fluid annually?
