I just installed my new rotors and calipers on the front tonight. Tommorrow morning I am starting the rear drums. I did several searches on brake bleeding, sorry if I'm beating a dead horse here.
I am using a Motive pressure bleeder and I have read that the porportioning valve and abs valve have to be manually operated to assure all air is out. I can't locate the "stem" that needs to be moved by hand. All I see is a rubber grommet on the front of each valve. Both valves are right at the MC.
On my calipers, I replaced the copper washers with new ones but I still am getting a slight leak under pressure on the driver front. Any suggestions on getting them to seal better?

 

I had a rebuilt caliper I had to use two washers on to stop the leak.
