Master brake cylinder (air booster) 800901159 XZ50K-3510002 251804668 - factory supplied from Mettlead
When it comes to heavy equipment safety, braking systems make no compromises. That's whymaster brake cylinder (pneumatic hydraulic booster) 800901159 XZ50K-3510002 251804668designed to provide the most reliable and stable braking in the most severe operating conditions. Also known as a master cylinder booster, this assembly converts pneumatic force into hydraulic pressure for smooth, predictable brake application. CompanyMettleadsupplies this part directly from the factory in China, which guarantees a competitive price and short shipment times for wholesale buyers around the world.
Functional benefits and benefits for your business
Trouble-free operation of the braking system
The pneumatic hydraulic booster 800901159 converts compressed air pressure into the hydraulic force necessary to operate the wheel brakes. Thanks to this, the operator of the equipment receives clear feedback on the pedals, and the braking distance remains stable even when the machine is fully loaded.
Increased service life and wear resistance
Internal seals and piston group are made of high-strength materials that are resistant to temperature extremes and aggressive brake fluids. As a result, the service interval increases and the cost of ownership decreases - which is especially important for fleets of equipment with intensive use.
Direct replacement without modifications
The part fully corresponds to the original mounting dimensions and connecting holes. This means you save installation time: installation takes the same amount of time as removing the old unit - no adapters or adapters required.
Benefits when purchasing in bulk
Since Mettlead operates on a factory direct supply model, middlemen are eliminated from the chain. Consequently, you get a lower purchase price with guaranteed high quality - an ideal combination for purchasing managers responsible for margins.

Real customer case: brake master cylinder 800901159 for a fleet in Central Asia
One of our regular partners - a distributor of spare parts from Uzbekistan - made a request formaster brake cylinder (pneumatic hydraulic booster) 800901159 XZ50K-3510002 251804668for its client operating a fleet of XCMG truck cranes on construction sites. Previously, they purchased similar units through an intermediary in a third country, which increased the price by 25–30% and extended the delivery time to 45 days.
After switching to direct procurement through Mettlead, the situation changed. First, the unit price decreased by 28%. Secondly, the first batch of 20 pneumatic hydraulic boosters 800901159 was shipped just 7 business days after confirmation of payment. In addition, the client took advantage of neutral packaging with its own labeling, which strengthened its brand in the local market. Based on the results of six months of operation, none of the supplied brake master cylinders failed - zero return under warranty.
Frequently asked questions about pneumatic hydraulic booster 800901159 XZ50K-3510002 251804668
How does a pneumatic hydraulic booster differ from a conventional brake master cylinder?
The classic master cylinder is actuated mechanically, directly from the brake pedal. The pneumatic hydraulic booster 800901159, on the contrary, uses compressed air pressure to create hydraulic force. This design provides significantly greater braking force with minimal physical impact on the pedal - this is critical for heavy equipment with a high mass.
What signs indicate a faulty air-hydraulic booster?
Pay attention to the following symptoms: the brake pedal sinks or becomes “wobbly”; braking distance increases; brake fluid leaks appear in the area of the master cylinder; You can hear a characteristic hiss of air when you press the brake. If at least one of these signs is present, it is recommended to promptly replace the unit with a new one - delay directly affects safety.
Are the numbers 800901159, XZ50K-3510002 and 251804668 interchangeable?
Yes, all three references refer to the same unit. Different numbers appeared due to the fact that different catalogs and accounting systems assign their own codes to parts. When ordering, you can specify any of them - the supplier will ship an identical part.
Do I need to change the brake fluid when installing a new air-hydraulic booster?
Highly recommended. Old fluid may contain moisture and wear debris that can damage new seals. Therefore, when replacing brake master cylinder 800901159, the system must be completely flushed with fresh DOT 3 or DOT 4 fluid and thoroughly bled to remove air.
What is the service life of pneumatic hydraulic booster 800901159 during normal operation?
If you follow the maintenance regulations and use high-quality brake fluid, the service life of the unit ranges from 3,000 to 5,000 operating hours, depending on the intensity of the load. However, it is recommended to carry out a visual leak check every 500 hours to help identify the problem at an early stage.
