Buying Guide: How To Choose A Rear Brake Master Cylinder Reservoir
What should I check first? Start with mounting hole spacing, diameter, and hose length to ensure compatibility with your master cylinder and brake lines. If possible, compare your current reservoir’s dimensions to those listed in product specs.
Material matters: Aluminium alloy bodies tend to resist rust and wear, while ABS or high-quality plastics keep weight down. Consider heat exposure and potential impact in off-road environments.
Compatibility considerations: Models referenced here cover Yerf Dog, Coleman, TaoTao, Helix, Arctic Cat, and similar small-run machines. If you own a mixed fleet, universal reservoirs are convenient, but always verify mounting geometry.
Installation ease: Look for designs described as easy to install, with flexible fitments, and strong airtight seals. Avoid units that require extensive modification or non-standard fittings.
Maintenance and replaceability: Choose reservoirs with straightforward access for periodic checks and refills. A robust seal reduces leakage risk, extending the life of the entire braking system.
FAQ
- Q: Will these reservoirs fit all 50cc–150cc Chinese ATVs?
A: Many are marketed as compatible with a wide range of models, but always verify mounting hole spacing and hose lengths for your exact machine. - Q: Are universal reservoirs a better pick for mixed bikes?
A: They offer flexibility for multiple machines, but ensure the length and connections align with each bike’s design. - Q: What material is best for durability?
A: Aluminium alloy bodies provide strong sealing and corrosion resistance; ABS is lightweight and impact resistant. - Q: Should I worry about installation difficulty?
A: Choose parts described as easy to install with good airtightness to minimize leaks and future maintenance. - Q: Do these reservoirs come with hoses or fittings?
A: Listings vary; confirm whether hoses, mounting hardware, and fittings are included before purchase. - Q: Can I replace just the reservoir or should I replace the whole master cylinder?
