bleeding (if done properly) takes less than 5 mins for both calipers
Top up fluid to max mark.
Get your friend to sit on the bike
You will look after the bleed nipple.
Now Open nipple , tell your friend to pull the lever slowly in.
(not fast & pumping like a young lad making a romance in a girl for the first time!!!)
close the nipple
tell your friend to release the lever
open nipple
friend slowly pulls lever
close nipple
friend releases lever
do that until you are happy.
then start on the other caliper.
I hope this helps
