Rear brake bleeding

[4corsa]

In case this hasn't already been covered, I was having trouble bleeding my rear under-mount Brembo caliper on my Scura. No matter how many times I bled it, I just couldn't get a firm pedal. Then I realized the problem is the bleeding nipple is located on the bottom. Air bubbles rise to the top and are trapped. So I unbolted the caliper and rotated it so the nipple was at the top and connected a tube. After just 3 bleeding cycles, all the air was pumped out and I got my firm pedal back.

Well done! This is a "must do."

 

Also, consider cleaning the pistons with brake cleaner and working them in and out alternately until they move evenly.

 

Adjust the foot lever actuation so there is some play at the master cylinder and inspect under the rubber boots at the master to be sure all is clean.
