▪ OEM mounting holes, push rod stroke and port threads match original parts for direct replacement without extra adjustment
▪ Precisely honed barrel reduces friction, ensures smooth piston movement, fast brake response and clean release
▪ High-strength built-in return spring maintains stable elasticity after repeated braking to avoid brake drag
▪ Complete oil-resistant seal kit resists air impact, mud and dust intrusion for long-term sealing
▪ High rigidity push rod resists bending under heavy braking load and guarantees steady braking force
▪ Compact structure fits original brake bracket space, easy to disassemble for brake maintenance
▪ Compatible with air tank, brake valve, air pipe, combination valve and other pneumatic spare parts of the same model
▪ Factory air tightness and stroke fatigue inspection screens sticking or leaking defective units for stable braking performance

FAQ 

Q：Can I keep working if the vent hole of brake cylinder leaks continuously?
A：It is not recommended. Leakage means internal seals are damaged and braking force will be insufficient. Stop and replace it promptly.

Q：What causes brake drag and failure to release?
A：It is usually caused by broken return spring, stuck seal or bent push rod. Replace the whole assembly instead of partial repair.

Q：What should be noticed during installation?
A：Clean pipeline dirt before installation to avoid scratch on barrel. Do not force push rod. Install new gasket and test action and leakage.

Q：What damage will water inside cylinder cause?
A：Water rusts barrel and spring and damages seals, leading to leakage and sticking. Drain air tank water regularly.

Q：Is weak braking force always caused by the brake cylinder?
A：Not necessarily. Check air tank pressure, brake valve and air pipe leakage first before confirming cylinder failure.

Q：How to store spare brake cylinder?
A：Store in dry and ventilated place, seal air ports, protect push rod from heavy load and impact to avoid bending.
