)Tips and tricks:
• Having a clean work environment is always important, but never more so than when doing brake work. Getting any sort of lube or grease onto the new brake pads will render them useless, so take a few minutes to not only tidy up before starting, but also wipe your workbench clean of any contamination that may be present from your last repair job.
• Avid recommends replacing brake pads when they get to be 3mm thick, which is about the thickness of two US dimes.
• The pad retaining bolt and E-clip are small items - put them somewhere safe where they won't get lost after removing them from the caliper. An old Tupperware container is perfect for this sort of thing.
• Always reset the pistons - push them fully back into their bore - before removing the old, worn out pads. You are likely to damage the piston if you push directly on it, which is why you always leave the old pads in place while doing this. Also, never reset the pistons with your new pads installed for the same reason.
• Even when a pad change is done correctly, a slight amount of brake drag may be present. Take the bike for a spin to break the new pads in and then recheck to see if the wheel now turns freely. If not, you may need to recenter the caliper by loosening the Avid CPS bolts, holding the brake on and then re-tightening the caliper bolts (a small amount of freehand fine tuning may also be needed to get it perfect
• New brake pads take time before they can deliver fully power. Avid says that it could take 20-40 stops before they get up to full power. Break them in by doing short hard stops, not by dragging the brakes.Avid Elixir Pad Replacement:
