What does this part do and what are the symptoms of wear?

The master cylinder is a key component that converts the force from the pedal into hydraulic pressure. In machines with a servo, its failure is indicated by the need to apply excessive force to the brake pedal, a delayed response, a "soft" pedal, or fluid leaks. This fault not only reduces comfort but also drastically increases stopping distance, posing a huge threat on the job site.

Why Choose Our Master Cylinder?

✔Restored Lightness and Precision

A new cylinder working with the servo restores the light pedal feel, which reduces operator fatigue and increases braking precision.

✔Guaranteed Sealing and Pressure

High-quality internal seals prevent brake fluid leaks and ensure proper pressure is maintained in the system.

✔Perfect Fit

Designed as a direct replacement, ensuring a hassle-free and quick installation without any modifications.

Important Fitting / Service Tips

1.Check System Compatibility

This master cylinder is exclusively for machines with servo-assisted brakes. It will not fit older models without this system.

2.Use New Brake Fluid

When replacing the cylinder, always use fresh, manufacturer-recommended brake fluid dedicated for JCB machines. Old fluid loses its properties and can damage the new cylinder.

3.Bleed the System

After installing the new cylinder, the entire brake system must be thoroughly bled according to the service manual. This is crucial to achieve full braking power.

Frequently Asked Questions (FAQ)

Question: Will this cylinder fit an older machine without a servo?

Answer: No, this model (15/920389) is exclusively for machines with a servo-assisted brake system. A different master cylinder is dedicated for non-servo machines.

Question: Why is my brake pedal still "soft" after replacing the cylinder?

Answer: The most common cause is improper bleeding of the brake system. Another possibility is a leak further down the system (e.g., in the hoses or calipers).
