Sierra Master Cylinder

[davidimurray]

Been playing with my brakes and not sure if my master cylinder is working correctly, When I pump the cylinder and put my fingers over the front two outlet and pump the cylinder I can feel the pressure building up.However when i do this for the rear outlet I can barely feel anything.

Also If I fill the reservoir with fluid, the rear outlet start to drip fluid without depressing the piston. Is this normal ?

Cheers
