avid brake bleed procedure
AVID BRAKE BLEED PROCEDURE
Avid brakes are the most powerful and precise hydraulic brakes on the market. A key reason behind this is the ability to optimize
brake performance with a perfect bleed. The goal of bleeding is to remove any air that is trapped in the hose, caliper, or lever. Air
trapped in a hydraulic brake system degrades the performance of the brake. The following instructions will walk you through our
simple bleed procedure.
Avid brakes come with hoses attached and bled. If you don’t need to change the hose length, you do not need to bleed the
system prior to installation.
