New Master Cylinder and Bleeder - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I replaced my original master cylinder with a new one and started bleeding the valve on top. My single line connects to the side and I plugged the very front hole with a fitting. My other C10 is exactly like this, however, my top bleeder screw is just spewing out fluid through the hole anytime I hit the brakes.... What am I doing wrong?

It sounds like the bleeder is not seated tightly or there is something in the seat. Pull the bleeder, inspect and clean if necessary. Then tighten again and see what happens.
