bleeding a new brake system

[SS Shaun]

so after weeks of working on my brakes and not figuring out what it was, i finally took the time to day and go over line by line to figure out what is wrong with my brakes. Took the lines apart and pushed some fluid down the pipes and it was coming out hooked everything back up and instead of putting it on the master i put the syringe in the lines and pushed fluid and it came out. we took the master off and did a bench bleed and we noticed that when we did the rear for some reason the fluid was coming out milky. it was full of air pockets little tiny ones. let it sit for a few and all the bubble went away. pumped again and the bubbles came back.

So my buddy said it seems like a seal on the inside of your master must be going bad and is getting air in every time you pump it. so i called summit and explained everything to them and they said yes you need a new unit. So they are sending me a new unit should be here by tuesday. so once we knew i was getting a new unit my friend said lets open it up and check it.
So we opened it and all of the seals are in good shape. everything seems fine. so then he started measuring everything and then we found the problem. the seal that sits in front of the rear res was about .020 to small for the bore of the master. he put in a make shift seal and we stuffed it back in and it started to pump fine no more milky fluid. we put it back on and fluid was coming out the rear like it should. so now i have it sitting on the shelf waiting to be returned. o and we took the seal back out didn't want to have an issue...lol lets see what happens now
