Quicksilver DOT 5 Brake Fluid 12 oz — Silicone-Based DOT5 for Powersports, Low Compressibility & High Boil Point

This brake fluid is formulated for vehicles and equipment that call for DOT 5 silicone fluid, delivering low compressibility, excellent corrosion resistance, and high boil points to help preserve braking performance under demanding conditions. It meets or exceeds MIL-PRF-46176 and MIL-PRF-46176B specifications and is intended only for DOT 5 applications — it must not be mixed with DOT 3 or DOT 4 fluids.

Will this fluid work in my powersports brakes?

Use Quicksilver DOT 5 only when your vehicle manufacturer explicitly specifies DOT 5 silicone brake fluid. Mixing different fluid types can damage seals and reduce braking performance. Always check the owner’s manual before replacing fluid.

• Designed exclusively for DOT 5 systems — not compatible with DOT 3 or DOT 4
• Matches DOT 5 manufacturer recommendations and warranty requirements
• Sold in a 12 oz bottle for top-offs or small-system servicing

How does it help braking performance under load?

This silicone-based fluid features low compressibility to maintain consistent pedal feel and response. Its high dry and wet boil points reduce the risk of vapor lock during heavy or repeated braking events, preserving reliable performance.

• Dry boil point approximately 500°F — resists vapor formation when hot
• Wet boil point around 356°F — maintains performance with moisture absorption
• Low compressibility supports consistent brake modulation and feel

Can it protect brake components from corrosion?

Quicksilver DOT 5 provides strong corrosion protection formulated to extend component life in hydraulic braking systems. It helps reduce internal rust and deterioration when used as directed, supporting longevity of calipers, lines, and master cylinders.

• Formulated to inhibit corrosion inside brake assemblies
• Meets military-grade specifications for protective performance
• Helps maintain peak reliability over service intervals

Is this fluid safe for warranties and maintenance?

When installed in systems that require DOT 5, this fluid meets or exceeds manufacturer and MIL-PRF standards and will not void compatible equipment warranties. Avoid cross-contamination with DOT 3/DOT 4 fluids to preserve system integrity and warranty coverage.

• Conforms to MIL-PRF-46176 and MIL-PRF-46176B standards
• Compatible with DOT 5 manufacturer warranty requirements when correctly used
• Comes in a sealed 12 oz container for clean handling and storage

Who is this for? Quicksilver 8M0128419 DOT 5 Brake Fluid is intended for powersport riders, marine operators, and small-vehicle owners whose braking systems specifically call for DOT 5 silicone fluid. It’s suitable for technicians and DIY mechanics performing top-offs or servicing small brake reservoirs who need a high-boil, corrosion-resistant silicone brake fluid in a convenient 12 oz bottle. If your vehicle requires DOT 3 or DOT 4, choose the correct fluid type instead of this product.
