• PAG (polyalkylene glycol) synthetic base oil - Provides excellent thermal stability and low residue formation at brake temperatures, supporting long-term lubrication in high-temperature caliper environments.
• Lithium-complex thickener, NLGI 2 consistency - Delivers a mechanically stable grease body that adheres to caliper pins and bores, resists softening at high temperature, and remains pumpable for line-fill or service.
• Wide service-temperature range (-40 °C to 200 °C) - Supports reliable operation from winter cold-soak through repeated high-energy stops, reducing torque shift and pin sticking across real-world duty cycles.
• Excellent anti-fretting performance - Formulated to maintain low frictional force between the caliper pin and bracket bore, helping prevent micro-sliding from turning into fretting corrosion and wear.
• Enhanced EPDM elastomer compatibility at 150 °C - Demonstrates limited volume and hardness change in EPDM at elevated temperature, helping protect boots and sleeves from swelling, softening, or cracking under sustained brake heat.
• Good corrosion resistance and washout behavior - Provides protection against rust in salt-spray environments and resists water washout, keeping pins and bores free-moving in wet, contaminated conditions.
• Low bleed and evaporation at high temperature (< 5% / 24 h @ 150 °C) - Helps keep grease in the pin/bore interface instead of migrating onto pads, rotors, or out of the joint, supporting long service intervals.
• Light-green color - Makes it easy to confirm correct product and coverage on the line or during service, reducing mis-lubrication risk.
• No intentional PTFE or PFAS; GM 9986340 approved - Aligns with OEM material strategies and regulatory expectations while meeting a key GM brake specification for caliper pin lubrication.

Seized or sticking caliper pins causing brake drag, uneven pad wear, or pull - G-3407’s high-temperature PAG base, lithium-complex thickener, and wide -40 °C to 200 °C range keep caliper pins sliding freely across harsh duty cycles, reducing drag and pad taper issues.

Fretting corrosion on pins and bores from constant micro-movement - The grease is specifically designed to maintain low frictional force and deliver excellent anti-fretting performance so micro-sliding does not generate red rust, pits, or wear that lead to sticking.

Boot swelling and failure due to elastomer-incompatible greases at elevated temperature - Enhanced EPDM compatibility at 150 °C helps maintain boot integrity, reducing the contamination and corrosion that follow seal damage in caliper hardware.

Grease migration onto pads/rotors or loss of lubrication due to bleed, evaporation, and washout - Low bleed and evaporation at 150 °C, coupled with good water-washout resistance, help keep G-3407 in the pin/bore interface instead of on friction surfaces or washed away.

Difficulty standardizing on a severe-duty caliper pin grease that meets performance and material-policy requirements - Because G-3407 is PAG-based, GM 9986340 approved, and contains no intentional PTFE/PFAS, it gives OEMs and fleets a single, globally applicable caliper pin grease that satisfies both engineering and compliance constraints.
