BRAKE FLUSHING

560 292 35 BRAKE FLUSHING Located on the drifter body, this cap seals a port within the flushing circuit. Its main job is to contain the flushing medium—either air, water, or a mix—and prevent it from escaping before it travels down the drill string. By maintaining a sealed system, it ensures consistent and effective clearing of rock cuttings from the borehole during drilling.

A failure of this cap leads directly to a loss of flushing pressure and performance. When flushing is weak, cuttings are not cleared efficiently, which can cause the drill steel to get stuck in the hole. This not only slows down the entire drilling cycle but also increases wear on the drill bit and can lead to premature equipment damage.

Look for signs of water or air leaking from the side of the drifter as an indicator that this cap or its seal may be worn. During regular maintenance, inspect the cap for cracks or damage. Replacing it is straightforward, but always ensure the flushing system is depressurized first to avoid injury.
