Much swearing at SRAM bleed process again. You'd think it would be clean with the syringes but end up with oil on everything.
Start with 15ml in the bottom, 5ml in the top as per instructions. The bit that confuses me is when you push the lever out using the lower syringe. When it gets to the point where the lever is fully out the syringe can put another 5+ml of fluid in. That near enough completely fills the top syringe so can't then create much vacuum to bleed to lever.
Then when I take the syringe off the caliper I lose a load of fluid (which suggests air is getting in, rather defeating the object of the bleed.
So much easier to bleed Hopes.

Don’t do this. Push the lever out and stop.

It doesn’t mean air is getting in, worth being on the ball with the bleed screw though
I just kept flusing the fluid from one syringe to the other, back and forth. Didn't bother pulling the lever at all as that just pulled the fluid from the top sirynge back in when releasing and if nearly empty, it can suck air in.
Keep it simple and just flush both ways. It worked for me.

Don't do that.
Close off and remove the bottom/caliper syringe - then pop the bleed screw back in. *only then* do you do the lever bleed. If you do it with the caliper syringe in, you'll not be bleeding the system - you'll be moving oil.
So much easier to bleed [s]Hopes[/s] brakes you've bled before.
I Just follow the procedure on the SRAM video on YouTube, listen to what the lady says and you won't die 🙂
I have noticed it takes absolutely loads of goes to get all the air bubbles out of the calipher.
I just do mini bleeds these days - ie just the lever end. Solves 90% of problems for 50% of the effort.
Despite my slightly messed bleed they actually felt really good today but being as wet as it was didn’t really get much of a work out.
Took the rear caliper off the bike and moved it around quite a bit - suspect that will have helped.
