Preventing contamination is mostly about controlling leaks and protecting the braking area. Start by inspecting nearby gearbox seals, hydraulic fittings, thruster seals, and lubrication points. Even small leaks can migrate onto linings over time, drastically lowering friction and causing unpredictable braking. Use correct grease quantities and avoid over-lubrication of pins/bushings. Where possible, apply grease in a way that cannot fling onto braking surfaces during rotation.
In harsh environments, consider protective covers or shields to reduce splash, dust, and water intrusion. For marine or port applications, corrosion control also matters—rust can trap contaminants and accelerate wear.
If contamination occurs, replacement is typically the safest option. Cleaning rarely restores consistent friction performance, and solvents can leave residues or damage bonding. After replacing linings, identify and correct the root cause (seal replacement, hose routing, drip trays, maintenance practices). For safety-critical systems, treat any contaminated brake as compromised until verified by inspection and functional testing.
