I feel like an amateur now using the syringe. Although my first bleed was a success and even the dude at the Path checked my work with a seal of approval. Wrenching is getting to be more and more fun for me. TFPU
That's a lot more than I do to bleed shimano brakes. I just attach the cup with some fluid in it, squeeze the lever til no more bubbles come out, and close it up. Works well and a lot faster and cleaner than all that ^^^
Well that was different. Looks like maybe I’ve been working too hard to do this job.
Looks interesting and less messy than I usually end up with. I will try next time I do brake work. Have you ever tried this method?
Other than the "dirt in the nipple" scenario, I see no reason to change what I have been doing with the syringe and cup.
I don't really see the need to soak the whole caliper unless the pistons are actually stuck.
Cool trick for out in the field...
LOL, that guy was hard to watch.
I think the one tip I’ll use from this is angling the bike rather than the brakes themselves so I don’t have to loosen then re-torque them.
ME: As I roll my bike into my LBS, "Hey bud can you bleed these damn brakes for me?"
LBS: "Sure, no problem"
ME: "OK great, see ya tomorrow, I'll ride my other bike in the mean time"
Can't be critical of a pro mechanic, for sure. It seems like it could take a bit of time for the gravity to do it's thing though (?). Last time I bled my brakes a month ago, I had the syringe hooked to the caliper bleed nipple and first thing I did after cracking the nipple open is pull a little fluid back out of the caliper with the syringe... a number of bubbles came out the caliper nipple. Not sure if/how long the gravity pushing fluid from the lever/top would take to get those boobles out through the caliper. I usually clean and lube the pistons before pushing them back anyway. I think whatever works for you, might give this version a try next time to see....
Looks like he was bleeding out the old black fluid for fresh fluid.
I happened to revisit this technique while bleeding both my bikes brakes recently. These are XT M785 and XT M8000 brakes. I used paper shop towels to mitigate the mineral oil drips and kept things relatively oil-free. Definitely helps to have the caliper lower and actually hanging by the hose. Close the bleed port and pump the lever to get the last bubbles from the master cylinder.
The bleeds worked out great.
