Wow. I will check the valve. My gutt is this chrome pan needs scuffing and good sealant. i already drained and was going to totally pull off tonight so I can clean perfect and start fresh.

Brakes - I do not know how to bench bleed..so no i have not. Someone else at work asked the same thing. How do I do this??

THANKS GUYS!!!!!

Basically you clamp your MC in a vise on your work bench, fill the reservoirs with fluid, and push in the plunger on the back of the MC until the air is purged out, then plug the holes so your fluid don't leak out until you can attach your brake lines. It's very hard to get the air out of the system unless you do this before installing. Google bench bleeding and watch some youtube videos to familiarize yourself, will be much more informative than me explaining. It's the best way I learn anyway.

The blue one piece should be better than cork. Make sure you have the right one and that you torque all bolts evenly, but not too tight. The front and back might need dabs of sealer on the corners. This video is the correct way to bleed the MC. Always bleed new master cylinders.
