Hi, I have just rebuilt my son's 2004 YZ 125 rear brake master cylinder with new cylinder kits from Yamaha. WHEN I tried to bleed the system. It seem do not built up the pressure. I suspected the cylinder check valve may be defected. Or do you have sample drawing of the component construct.Thank you
