    How are kart brakes bled on calipers with no bleed screws? They appear to be just plugs in a hole. Are bleed screws meant to be added?

    You don’t need bleed screws, you just need a bolt you can take out that lets the air out.

    Those are the bleeder screws.  The easiest way to bleed those brakes is with a gravity brake bleeder.  Or can do a bottle and put in the top of the master cylinder.

    First need to make sure the brake pucks are pushed against the brake pads.  I do this by using my brake bleeder attached to the MC.  with the valve closed I pushed the brake pedal then open the valve.  The fluid will then run back into the bleeder and then I would take out the screws in the caliper (bleed screws) and let the fluid drip out until bubbles stop.

    The karts with springs on the brakes you cant pump bleed them like you do cars.   You push on the brake let the fluid out, tighten the bleed screws let off the brake you will make a vacuum in the brake system and pull the pistons off the pads. (with spring return brakes)

    Thanks guys.

    I wanted to have at least a concept of how it was handled and the tips and tricks.

    The CRG’s we have use bleed screws that I can relate to. We also have 3 others that have the plugs only.  I have a Mityvac capable of bleeding brake but have never used it for brake bleeding.

    It is just really the air bubbles rising to the top and having a way to temporarily vent the air, then reseal.
