Remote Clutch Master Cylinder Fluid Reservoir Kit
The Rawsomes kit is designed for hydraulic clutch systems that use a remote fluid reservoir. It includes a rubber hose and mounting bracket for flexible placement away from heat or vibration—an advantage for motorcycles, dirt bikes, and ATVs. This kit can also function as a remote reservoir for some rear brake master cylinder setups. Pros include straightforward replacement of cracked or leaking oil cups and broad applicability. Before purchase, verify hose routing, reservoir capacity, and compatibility with your specific clutch line fittings to ensure a clean, leak-free install.
Wilwood GS Compact Remote Master Cylinder
This compact Wilwood model features a 0.75-inch bore and an 8-inch overall length, delivering precise hydraulic control for clutch or brake applications. The unit sports a durable high-strength aluminum body with a protective coating, designed for endurance in demanding racing or street duties. A remote inlet configuration using standard 7/16-20 threads makes plumbing straightforward for remote setups. When selecting this cylinder, check compatibility with your line sizes, mounting location, and whether the remote inlet aligns with your existing hose routing for a seamless installation.
Wilwood Compact Master Cylinder Kit
Wilwood’s compact master cylinder offers versatility with a 0.875-inch bore and a compact footprint, suitable for direct or remote reservoir configurations. The kit’s modular design supports diverse mounting styles, including flange or remote fittings, making it adaptable to tight engine bays or customized builds. Review your vehicle’s pedal ratio, line compatibility, and reservoir requirements to ensure the kit matches your clutch or hydraulic handbrake system. This option is well-suited for enthusiasts seeking a balance between size, performance, and install ease.
Qiilu Remote Master Cylinder Aluminum 0.75 Bore
Qiilu’s remote master cylinder uses aluminum alloy for enhanced durability and wear resistance, designed to meet OEM-like reliability. It’s positioned for hydraulic handbrake or clutch installations where a durable, heat-resistant remote reservoir is beneficial. The bore size of 0.75 inches supports a strong hydraulic signal, but confirm compatibility with your master cylinder cap, hose diameter, and mounting points. Qiilu emphasizes durability and stable performance, making it a solid choice for aftermarket hydraulic systems that demand consistent reliability in variable operating conditions.
Dorman CM39903 Clutch Master Cylinder
Dorman’s CM39903 provides a direct replacement option for select Acura and Honda models, designed to match the original master cylinder’s feel and performance. It emphasizes precise fit, durable materials, and compatibility with standard brake fluids. For remote setups, this unit shines when used as part of a broader rebuild that preserves OEM pedal feel and hydraulic response. Ensure the Dorman unit matches your vehicle’s year, make, and model, and verify compatibility with your clutch line routing and reservoir integration if you’re adapting it to a remote configuration.
Buying Guide: Key Purchase Considerations
When choosing a remote clutch master cylinder, consider the following criteria to ensure you select the best option for your vehicle and riding or driving style:
- Application and compatibility: Confirm whether the cylinder is intended for clutch use, brake use, or both. Verify bore size, inlet/outlet threads, and mounting style to match your system’s requirements.
- Remote reservoir feasibility: Assess space for the reservoir, hose routing length, and heat exposure. Remote setups are ideal when the main reservoir sits in a cooler, protected area to reduce fluid degradation and swelling.
- Material and build quality: Aluminum bodies with protective coatings are common for longevity in dirt, heat, and vibration. Check for corrosion resistance and ease of maintenance.
- Installation complexity: Some kits include mounting brackets, hoses, and fittings; others require additional components. Plan for possible pedal ratio changes or line routing adjustments.
- OEM compatibility: For car applications, verify that an aftermarket unit matches OEM specifications or is compatible with the vehicle’s brake/clutch system to avoid pedal feel changes or leaks.
- Reliability and serviceability: Look for rebuildable designs or reliable replacement parts, particularly for remote master cylinders used in performance or off-road contexts where maintenance access may be limited.
- Price and availability: Compare price points across brands and check for availability of spare hoses, seals, and mounting brackets to minimize downtime.
In practice, a remote reservoir kit from a reputable brand can simplify installation and heat management for motorcycles and ATVs, while compact master cylinders from Wilwood offer precision in tight spaces. For automotive use, Dorman and Qiilu provide direct-replacement and aftermarket options that balance durability and compatibility with OEM specifications. Always validate hose diameter, thread sizing, and mounting clearance before purchasing, and consult your vehicle’s service manual or a qualified technician if you’re unsure about compatibility.
