I’m nearly done a brake job on my 360. Bleeding the last valve (drivers outboard screw) but not getting fluid out. The on-board one was a little plugged but I got it flowing by taking out the screw, cleaning it and finally poking into the caliber to free up the plug. But the outside one is dry. Any ideas? Can I shoot some compressed air into it? Any other next steps? I should mention, it looks like the fluid hadn’t been changed in a long time. Possibly since the blue stuff was used. So I’ve been running a lot of fresh fluid through the system. Using a hand vacuum pump as I couldn’t get the motive device to seal on the master cylinder.
