When is replacement necessary?
Experienced mechanics know that the brake system signals problems long before failure. Here are typical situations in which replacing the pneumatic hydraulic booster 4120000675 becomes inevitable:
- Brake fluid leak— oil smudges on the cylinder body or under the pedal assembly indicate wear of the cuffs.
- Broken brake pedal- if the pedal goes to the floor without resistance, the internal seals have lost their tightness.
- Insufficient braking force— the loader cannot confidently stop when loading, despite working pads and discs.
- Extraneous sounds when pressing the pedal- a whistle or hiss of air indicates destruction of the pneumatic circuit of the amplifier.
Timely replacement of the master brake cylinder 4120000675 prevents expensive repairs of the entire brake line and, more importantly, eliminates emergency situations at the site.

Frequently Asked Questions about Brake Master Cylinder 4120000675
Is the 4120000675 air power steering suitable for my SDLG loader?
Yes, this brake master cylinder is a direct replacement of OEM part number 4120000675 and is installed on SDLG wheel loaders without any modifications. However, if you have a rare modification, send us the VIN or a photo of the old part - we will confirm compatibility within a few hours.
What is the service life of pneumatic hydraulic booster 4120000675 from Mettlead?
If maintenance regulations are followed and high-quality brake fluid is used, our cylinder can withstand at least the same operating hours as the original part. The secret is in 100% incoming inspection of the cuffs and final honing of the mirror.
Why is brake fluid leaking from the cylinder?
The most common cause is natural wear and tear on the inner seals and o-rings. Over time, rubber loses its elasticity under the influence of temperature and pressure, causing liquid to seep through the resulting gaps. In this case, replacing the entire assembly 4120000675 is the most reliable solution, since repair kits do not always restore factory tightness.
Is it possible to repair the pneumatic hydraulic booster instead of replacing it?
Theoretically, the cuffs can be replaced, but practice shows that if the cylinder mirror wears out, even new seals will not ensure the same tightness. In addition, the cost of a new brake master cylinder 4120000675 from Mettlead is often comparable to the price of a quality repair kit and mechanic work.
How to store spare pneumatic hydraulic booster 4120000675?
Store the part in its original packaging in a dry place at a temperature of +5 to +35 °C. Avoid direct sunlight and contact with harsh chemicals. Under such conditions, the shelf life without loss of characteristics is at least 2 years.
