Bleeding a brake is one of the easiest tasks ever. At first for me it was daunting because I didn't have the correct fluid but when I learnt that it could be done with water the task became so much simpler. I fitted and bled my new RB lever in about 5 minutes last night, fill cup with water, get syringe, fill syringe with water, unscrew bleed bolt on slave, screw in bleed pipe, attach syringe to bleed pipe, unscrew bleed bolt on lever, depress syringe, wait until water comes out of lever, screw in bleed bolt back into lever, remove bleed pipe, screw bleed bolt back into slave, sorted. Took me longer to write that than it actually takes.
