The clutch master cylinder is the core hydraulic component of the clutch system in a manual transmission vehicle. When the driver depresses the clutch pedal, the master cylinder converts the pressure into hydraulic pressure, which is then transmitted through oil lines to the driven cylinder, ultimately disengaging the clutch disc and allowing for smooth gear shifting.

Market Background: The LADA NIVA is one of the world's longest-produced off-road vehicles, continuously produced since 1976. It has a large market presence in Russia, CIS countries (Uzbekistan, Kazakhstan, Belarus, etc.), Eastern Europe, Central Asia, and parts of Latin America. Due to the continuous production of this model, vehicles from different eras require maintenance, and the clutch master cylinder is a frequently replaced part.

Core Functions
Hydraulic Pressure Conversion: Precisely converts pedal force into hydraulic output, with linear response and clutch pedal feel consistent with the original.
Sealed Hydraulic Circuit: Built-in high-precision sealing components effectively prevent brake fluid leakage and maintain long-term stable pipeline pressure.
Off-Road Performance: NIVA vehicles are commonly used in harsh environments such as off-road, agriculture, and forestry. The seals in this product possess excellent temperature resistance and fatigue resistance, adapting to frequent pedaling and complex road conditions.
45° Flange Installation: The mounting flange features a 45° bevel design, perfectly matching the original NIVA vehicle's interior space layout, ensuring precise installation and requiring no pipeline modifications.
Multiple Part Number Coverage: Simultaneously corresponds to multiple circulating part numbers such as 4190178, 2101-1602610, and 2121-1602610, facilitating parts suppliers' system search and code matching.

It is more competitively priced than the original parts, making it suitable for the repair and replacement market.

Q2: Are the 2121 and 2131 models compatible?
A: Yes. Both models (2121 short wheelbase version and 2131 long wheelbase version) use the same clutch master cylinder, and the XUI3514A is compatible with both. For further confirmation, please contact us using the vehicle's VIN code.

Q3: With so many part numbers, how do I confirm which one corresponds to my order?
A: This product corresponds to the following part numbers: 4190178, 2101-1602610, 2121-1602610, and 2101160261010. All four part numbers point to the same specification product. You can search for any of the part numbers in the system; the results will be consistent.

Q4: Is the M12×1.25 thread common locally? Does installation require special tools?
A: M12×1.25 is the standard thread specification for hydraulic lines in LADA series vehicles. It is widely familiar to repair shops in Russia and the CIS market. Installation can be completed using a regular wrench; no special tools or modifications are required.
