CM246
This product's OE number is 306105773R / 306100642R (original factory markings 30 61 057 73R / 30 61 006 42R). It is a universal part for Renault's B platform models. One part number can cover multiple best-selling models, meaning a more streamlined SKU and more concentrated inventory for the buyer. This component is under constant stress and sealing. Over time, the seals will age, commonly manifesting as "soft pedal, longer travel, and jerky shifting." Troubleshooting these issues often reveals leaks in the master cylinder or internal wear.
Specific Applications: According to the original manufacturer's compatibility data, this master cylinder is suitable for:
RENAULT Clio IV Hatchback (chassis code BH), circa 2012–2019 models
RENAULT Clio IV Grandtour (chassis code KH)
RENAULT Clio IV Van (van)
RENAULT Clio IV Estate Van (van, chassis code KH)
RENAULT Captur (first generation, chassis codes J5_, H5_), circa 2013–2019 models. The first generation Captur and Clio IV share the same B platform, with many common chassis and powertrain components, which is why this master cylinder is compatible with multiple models. It is recommended to provide the VIN code or the OE number from your existing master cylinder for verification before ordering to ensure there are no minor differences between different models and engine versions.
Core Functions:
Converts pedal force into hydraulic pressure, driving the clutch slave cylinder.
Controls clutch engagement/disengagement timing, directly affecting shift feel and smoothness. Internal seals, pistons, and return springs ensure leak-proof hydraulic lines.
One OE number covers multiple body styles for Clio IV and Captur, facilitating unified inventory management for buyers.
Procurement Motivation:
Launch Own Brand: Clio IV and Captur have large market share in Europe. These frequently replaced parts are suitable for creating a standard SKU under an Own brand, sold on platforms like Amazon and eBay or in local auto parts markets, building brand recognition.
Bulk Retail Supply: Because one part number covers multiple vehicle/body versions, bulk purchasing ensures stable sales volume for a single model, suitable for long-term partnerships with chain auto parts stores and repair networks, reducing the complexity of model management.
Cost Optimization: Compared to purchasing separate master cylinders for Clio IV and Captur (which would result in different SKUs if purchased separately according to brand-specification), using a single universal OE number reduces the number of SKUs and lowers the minimum order quantity, leading to lower overall procurement and inventory management costs.
The core problem this product solves for overseas customers: Clio IV and Captur are both high-selling models in the European market, with stable and consistent demand for their clutch master cylinders over the years. However, brand-specification parts are expensive, and the supply of some niche versions is unstable. Direct factory supply of products with the same OE specification allows auto parts wholesalers, chain repair shops, and e-commerce sellers to obtain supplies at more competitive prices. Furthermore, because one part number covers multiple models, procurement and inventory management are more convenient.
