• Fully enclosed wet oil bath design, good dust-proof and mud-proof performance, suitable for harsh construction sites.
• Copper-based friction plates, stable friction coefficient, high heat resistance, not easy to burn under frequent braking.
• Alloy steel separator plates with high flatness, uniform contact, reduce partial wear of friction discs.
• Hydraulic piston drive, sensitive response, smooth braking without sudden lock-up.
• OEM installation dimension and oil port layout, direct replacement without modification.
• Good heat dissipation by oil bath cooling, effectively control temperature rise during continuous braking.
• Strong anti-pollution capability, resist the influence of tiny sediment mixed in brake oil.
• Batch hydraulic pressure and sealing inspection before delivery to eliminate leakage risk.

FAQ 

Q：What signs mean the brake needs replacement?
A：Obvious insufficient braking force, long braking distance, abnormal metal grinding noise inside brake, continuous oil leakage, brake overheating and brake dragging.

Q：What should be noted during brake installation?
A：Clean the hub mounting surface and hydraulic pipeline before installation; check piston seals; tighten bolts according to specified torque; replace new brake oil after assembly and conduct air bleeding test.

Q：What are common causes of brake damage?
A：Frequent heavy emergency braking; brake oil deterioration or contamination; oil shortage leading to poor cooling; mud penetrating and abrading friction plates; long-term brake dragging.

Q：Can damaged brake assembly be repaired and reused?
A：Minor seal damage can be repaired by replacing sealing kits. If friction plates are severely worn or steel plates deformed, overhaul cannot guarantee long-term safety; better replace the whole brake assembly.

Q：How to inspect brake during daily maintenance?
A：Check brake oil level, oil quality, braking performance and oil leakage before heavy-load operation. Listen for abnormal noise when braking.

Q：What failures will a failed brake cause?
A：Failed brake will result in insufficient braking force, extended braking distance, which brings great safety hazard. Severe damage may lead to loss of braking ability and traffic accidents.

Q：Can this brake fit other loader models?
A：This brake assembly is custom made for ZL50G/ZL50GL. Mounting size, torque specification and hydraulic interface are exclusive. It cannot be fitted directly on other models without modification. Wrong replacement will cause braking failure risk.
