My 2005 Sierra, with only 42,000 miles on the odometer (legit - I bought the truck new in December, 2004), has been stricken by the corroded brake lines syndrome.

So far, only one line has burst - a line to the left front brake - spraying brake fluid all over the exhaust manifold and leaving me with rear brakes only.

Before spending the money to replace the whole system, I thought I would for the time being at least render the truck drivable by replacing only the burst section.

I'd like to know, before borrowing a car and heading off to the parts store for a generic length of pre-flared tubing, what the tubing diameter is (i.e. 1/4" or 6mm) and what the thread gauge on the fittings is.

Any help will be appreciated.

Take a piece of tubing with you and a fitting. Match the threads on the piece at the store and your fitting. 6mm is not the same as 1/4 is closer to 6.3mm at least I have a S-K 6.2mm socket for 1/4 nuts on my metric set.
