• PAG (polyalkylene glycol) base oil
• Delivers excellent oxidation stability, low residue formation, and very good compatibility with common automotive elastomers such as EPDM, helping protect dust boots and seals over time.
• Anti-fretting design for metal-to-metal joints
• Formulated specifically to minimize fretting corrosion and wear in metal/metal pairings like brake caliper guide pins that see constant micro-movement and vibration.
• Wide service temperature range (-40 °C to 150 °C)
• Supports smooth sliding and consistent torque from cold-climate starts to elevated brake temperatures, reducing the risk of pin seizure across real-world duty cycles.
• Good corrosion protection
• Protects steel pins, sleeves, and bracket bores from rust and corrosion, even in the presence of moisture, de-icing salts, and road splash typical of brake environments.
• Good elastomer compatibility
• Tested with EPDM and other elastomers to limit volume swell and degradation, helping maintain dust boot integrity and sealing performance over the life of the brake caliper.
• Low bleed and evaporation (< 5% at 150 °C)
• Keeps the grease where it is applied instead of migrating onto pads, rotors, or friction surfaces, helping preserve braking performance and avoid contamination-related issues.
• Stable consistency (penetration 265–305, NLGI 2-type)
• Provides a workable, stable grease body that is easy to apply by hand or grease gun yet resists being flung off or displaced during braking and suspension movement.
• Resistance to oxidation
• Maintains lubricating properties over extended time and temperature exposure, supporting long service intervals without hardening or forming deposits on critical sliding surfaces.

Seized or sticking brake caliper guide pins that cause uneven pad wear, brake drag, and pull MOLYKOTE® G-407’s anti-fretting formulation and PAG base keep pins freely sliding over time, reducing the risk of seizure and helping maintain even pad loading. Boot swelling, cracking, or degradation caused by incompatible greases The elastomer-compatible PAG chemistry helps protect EPDM dust boots and seals, avoiding swell or softening that can let contaminants into the guide pin bore. Corrosion and fretting at caliper pins in high-moisture, salted-road environments G-407 combines corrosion inhibitors with an anti-fretting film to limit rust and micro-wear where metal surfaces move under vibration, protecting hardware in harsh climates. Grease migration onto pads or rotors that leads to reduced friction and warranty concerns Low bleed and evaporation at 150 °C help keep lubricant confined to the pin and bore interface, reducing the chance that excess grease will travel into the friction zone. Inconsistent caliper motion and noise at low temperatures Controlled low-temperature torque and stable NLGI 2-type consistency support predictable pin movement and help reduce cold-start sticking, judder, or clunking linked to guide pin issues.
