Brake system reliability and durability were being compromised by heavily contaminated cooling oil resulting in premature failures and reduced component life. All four brakes share a common reservoir and hydraulic fluid, and the factory system is unfiltered. Contamination in any one brake assembly can contribute to wear in other parts of the brake system. Most of the contamination in the fluid is ferrous.

These images represent Mag-Shield performance over a period of 5000 hours, in a 994H loader operating at an Australian mine site. During this timeframe, there were no failures within the brake cooling circuit. Over the course of normal operation, 50 grams of ferrous material was collected by the Mag Shields. Capturing the material that is produced during normal operation is key to improving oil cleanliness and component life, which helps mitigate
failures. The result: less disruption for operations, planning and maintenance; improved availability and significant savings.
