I like Avid bleed steps for Shimano brakes...
I used my Avid syringes on a set of M988s for my trail bike...
Has some extra attachments from a Reverb bleed kit so I clipped the brass nipple off the end of one syringe attachment and used an old Hayes bleed nipple spring to attach the syringe on to the caliper bleed nipple. Using the Avid bleed method....pull a vacuum at the caliper w/ the lever closed to pull out all the air and degassed the fluid from the line and caliper. Then closed the caliper bleed nipple (but leave the syringe attached) after pushing in as much fluid as the syringe/system will allow. Then I pulled a vacuum on the lever to get the MC's air bubbles out and also pushed as much fluid into the system as allowed before buttoning up the MC/lever. Deviated from the Avid steps here...opened the caliper and fine tuned the bite point/feel at the lever to match the front w/ rear. This step took a bit of fussing, but I managed to get the lever to feel identical to my '11 Codes (both the Codes and M988s are on Goodridge lines).
Next project is to pair a M820 4-pots caliper to the M988's MC for the front end of that trail bike This might be a pretty interesting setup for those lighter and/or weight conscious DH riders...?

- Did you actually bleed the brakes?
- Did you just attach the funnel, then squeeze the handle to let more fluid in?

Zombie thread resurrection...
Hey, has anyone noticed the 820's pads rattling around in the caliper making all sorts of racket when your bike is plowing over chunder? I'm getting a lot of this...wondering if I just need to flair out the pad spring?
havnt experianced it, buthave heard of it on shimano brakes,,, there was a vid on youtube about it, where some guy cut a small piece of innertube to make a rubber band to put round the pads to stop them doing it,

Hey thanks! I'll give that a go. Not sure if it's the radiators rattling on the caliper body, but can't hurt to try

Gotcha. And, I think I saw my local Checkers had small blister packs of the stuff at the counter... Thanks!
