BRAKE BLOCK

BRAKE BLOCK 8440 3601 59 Acting as the primary friction element within a brake assembly, this block presses against a rotating disc or drum to safely stop movement. It is typically found in the feed system or rotation unit, where it is essential for holding the drifter steady. This holding function is crucial for accurate hole collaring and for preventing unwanted movement of the feed beam while adding or removing drill rods.

The reliability of the entire braking system depends on the condition of the brake block. A worn or contaminated block can lead to brake slippage, which compromises both safety and drilling accuracy. If the brake slips, the feed can creep forward or backward, affecting the straightness and intended angle of the hole. Using the correct replacement part ensures the brake performs as designed, providing consistent and predictable stopping force.

Listen for grinding noises or watch for any unintended drift in the feed or boom, as these are common signs of a worn brake block. During routine maintenance, visually inspect the thickness of the friction material. Always replace blocks before they wear down to the metal backing plate to avoid damaging the brake disc.
