Installing rear hydraulic brake light switch ?
Posted December 19, 2002 - 10:27 AM
Merry Christmas and a Happy new year to all.
I just installed a home made light kit on my WR. I kept the original 12 v ac for headlight and tail light. I added a 3 function handlebar switch and wired the hi-lo beam to it. A 1.2 amp battery is installed under the cover of the air filter box. I took off the snorkel, added 3 unifilter breathers. The batt feeds the horn and a relay for the Acerbis turn signals. I added an inline fuse, a main switch and a 2 pins plug connected to the battery for charging duty. This set up turns my bike into a machine that will keep me and the local police happy.
I'm going to install a hydraulic brake light switch to the rear brake unit. I'll replace the original banjo bolt with the pressure switch, then I have to bleed the system.
Some people are convince that I absolutly need to use a vacuum hand pump tool to perform this task.
Do I really need this tool ???
Or can I achieve proper bleeding by the regular method ? (tube in a can full of brake fluid and pumping til no more air bubbles come out)
Thanks for the replies
Best wishes to you and to your families

Now its time to bleed
With cap off reservoir and nipp loosened, slowly push rear brake lever down to the full stroke. You will see fluid cycle through the loop and suck back a little when the lever returns. As you let up on the lever, add fluid to the reservoir. Keep going until you see the air bubble pass through the loop (it was introduced when you changed the banjo bolt). Tighten nipple, top off res., and replace cap and you're finished. Get any fluid off the paint asap.
I got the loop trick from the insert from the bolt from Baja Designs. It works sweet

The job is done and everything seems to be OK. The bike is still in the basement for the most part of the winter , so I'll know if the job was done right when I'll ride the beast.
Right after I complete the light set up on my bike, I'll start to work on grease nipples insertions. more fun to come .
