... just ride it until the stock back brake line fails right at the bend coming out of the cylinder. When you push the pedal down, it will squirt brake fluid all over the hot exhaust pipe against which the brake line itself practically lays, and at which the banjo bolt is aimed.
If you're lucky like me, the plastic guide will catch fire.
It's helpful if you can limp into a Suzuki dealership that doesn't stock brake lines
They apparently have a policy of happily supplying you with the bucket of water if you run into the dealership and tell them your bike is on fire in front of their store.
After you throw a bucket of water on it, you can disconnect the pedal (to avoid future accidental discharges) and zip-tie the hose to the frame to keep it away from the exhaust pipe. Be sure to round off the banjo bolt first with the POS wrench in the tool kit while trying pointlessly to pull the brake line.
Ask the dealer if he wants to take a slightly used Vee as a trade in on a new one - that earns the story about there are NO Stroms left anywhere - and the one sitting on his showroom floor is already sold, so don't even look at it.
That should allow you to make the 40 miles home to order Galfer SS brake lines. If you stick to the slab, the wind will prevent the flames from returning.
