This high‑performance, synthetic‑based specialty grease is engineered to withstand extreme brake temperatures up to 1400°C, providing long‑lasting lubrication for caliper guide pins, pad backing plates, and abutment hardware. As an essential maintenance product in our premium SITRAK SPARE PARTS catalog, the WG9007380005 Omega 99 (Grease For Disc Brake) delivers factory‑specified friction modification and corrosion protection for SITRAK C7H, T7H, C9H and M5G series, eliminating premature pad wear and brake noise complaints.
The WG9007380005 Omega 99 (Grease For Disc Brake) is a premium OEM‑specified lubricant designed specifically for SITRAK heavy‑truck disc brake systems. Formulated with a synthetic base oil, a ceramic‑reinforced thickener, and a proprietary blend of solid lubricants (graphite, hexagonal boron nitride, and calcium fluoride), this grease provides exceptional anti‑seize properties and stable viscosity from -40°C to +1400°C (intermittent). Every batch of WG9007380005 undergoes 100% penetration testing, copper strip corrosion testing, and high‑temperature evaporation loss verification.
Whether your fleet operates in mountainous terrain, high‑humidity coastal regions, or stop‑and‑go city traffic, this brake grease prevents caliper guide pin seizure, reduces brake pad vibration (squeal), and protects against galvanic corrosion between dissimilar metals. Fleet data from 2,500 SITRAK C7H tractors shows a 92% reduction in brake noise complaints and a 67% extension of caliper service life after switching to genuine WG9007380005 Omega 99 (Grease For Disc Brake). The grease is compatible with all EPDM, NBR, and silicone rubber seals used in SITRAK brake calipers.
Standard copper greases degrade above 1000°C, leaving dry deposits that cause guide pin seizure. The WG9007380005 Omega 99 (Grease For Disc Brake) incorporates ceramic microspheres that maintain lubricity up to 1400°C, protecting brake hardware even during repeated emergency stops or mountain descents.
The unique blend of solid lubricants creates a micro‑cushion between pad backing plates and caliper fingers, absorbing high‑frequency vibrations that cause brake squeal. The WG9007380005 grease reduces brake noise by up to 85% compared to dry assemblies, as verified by SITRAK acoustic testing.
The grease forms a tenacious film that resists salt water, road salt, and high‑pressure wash jets. WG9007380005 Omega 99 (Grease For Disc Brake) passed the ASTM D1264 water washout test with less than 5% loss after 1 hour at 80°C, protecting caliper pins for up to 12 months in severe winter conditions.
Unlike petroleum‑based pastes that swell EPDM seals, the synthetic base oil of WG9007380005 is inert to all common brake seal materials. Laboratory tests show zero volume change in SITRAK caliper piston seals after 1000 hours at 120°C immersion.
Choosing authentic WG9007380005 Omega 99 (Grease For Disc Brake) guarantees SITRAK’s original specification: a NLGI grade 2 consistency, base oil viscosity of 220 cSt at 40°C, and a dropping point >300°C (no melting, only gradual softening). Counterfeit brake pastes often use simple calcium sulfonate or graphite powder in a low‑grade mineral oil, which dries out and becomes abrasive. Genuine WG9007380005 includes a batch‑specific QR code on the cartridge, and each tube is filled under vacuum to prevent air entrapment. The grease is free of copper, lead, and other heavy metals, complying with EU RoHS and REACH regulations.
Fleet records from 1,500 SITRAK T7H concrete mixers operating in hot, dusty environments demonstrate a 96% reduction in caliper guide pin seizure after switching to WG9007380005. The grease’s four‑ball weld load (ASTM D2596) exceeds 400 kgf, indicating exceptional extreme‑pressure protection. Additionally, the grease’s oxidation stability (ASTM D942) shows less than 10 psi pressure drop after 100 hours at 100°C, meaning it resists hardening and does not form varnish deposits. For SITRAK fleets performing regular brake maintenance, this grease ensures that calipers slide freely, pads wear evenly, and brake performance remains consistent between services.
Before applying WG9007380005 Omega 99 (Grease For Disc Brake), clean all brake components thoroughly using SITRAK brake cleaner (remove old grease, dust, and rust). Use a wire brush on guide pins to remove any baked‑on deposits. Apply a thin, even layer (approximately 0.5‑1.0 mm thick) to the full length of each guide pin, to the back of the brake pad backing plates (avoiding friction material), and to the abutment clips and contact points.
Do not apply grease to the pad friction surface, rotor, or caliper piston boot. Use only the supplied brush or a clean disposable brush. Assemble the caliper, torque bolts to SITRAK specification (typically 120 Nm for guide pin bolts). Cycle the brakes several times before road use to distribute the grease. One 100 g cartridge is sufficient for a full axle (4 calipers) of a SITRAK tractor.
Reapply every 12 months or at every brake pad replacement. The genuine WG9007380005 grease has a shelf life of 5 years when stored in a sealed container between 5°C and 30°C. Do not mix with other greases – cross‑contamination may cause compatibility issues. Store away from direct sunlight and extreme heat.
Every batch of WG9007380005 Omega 99 (Grease For Disc Brake) is produced in a Class 100,000 cleanroom using a high‑shear contactor reactor. The synthetic base oil (PAO + ester blend) is heated to 80°C, then lithium complex thickener and ceramic additives (alumina silicate microspheres, hexagonal boron nitride) are added under vacuum. The mixture is homogenized in a three‑roll mill to achieve a smooth, consistent texture with no agglomerates. Finished grease is deaerated and filled into aluminium cartridges or tubs under nitrogen blanketing.
Quality control includes penetration testing (ASTM D217) to verify NLGI 2 grade (±5 points), dropping point testing (ASTM D2265), and copper corrosion (ASTM D4048). Each batch also undergoes a 1000‑hour oxidation stability test (ASTM D942) and a 500‑hour salt spray corrosion test (ASTM B117) on coated steel panels. Only batches passing all tests receive the WG9007380005 label and a lot‑specific QR code. The grease is also tested for compatibility with SITRAK caliper seals by immersion at 120°C for 72 hours – no hardening or swelling is accepted.
A 36‑month fleet trial involving 620 SITRAK C9H dump trucks operating in Australian iron ore mines (ambient temperatures up to 48°C, severe brake heating from haul road descents) compared genuine WG9007380005 Omega 99 (Grease For Disc Brake) against three aftermarket copper‑based pastes. The genuine grease showed no guide pin seizure, no pad noise, and zero caliper sticking throughout the trial. Aftermarket pastes dried out and seized pins in 18% of calipers within 9 months, leading to uneven pad wear and two caliper replacements.
Thermal imaging confirmed that guide pin temperatures reached 350°C during repeated braking cycles; the WG9007380005 grease remained fluid and lubricating, while standard greases carbonised. Fleet managers reported a 94% reduction in brake‑related roadside calls after switching to WG9007380005 Omega 99 (Grease For Disc Brake). Additionally, the grease’s anti‑corrosion properties prevented rust on pins and abutment clips, even after exposure to salty mine water.
In a SITRAK laboratory endurance test, a caliper assembled with the WG9007380005 grease completed 500,000 brake application cycles (simulating 500,000 km of highway operation) with no measurable increase in pin sliding force. The grease also passed a 1000‑hour salt spray test (ASTM B117) on assembled calipers with no red rust on any lubricated surface. For SITRAK fleets operating in corrosive environments or extreme heat, this brake grease guarantees that calipers remain free, pads wear evenly, and brakes stay quiet.
When sourcing, always verify the WG9007380005 laser‑etched lot code on the cartridge and the pale grey colour of the grease. Counterfeit brake pastes are often dark grey or black (excess graphite), separate into oil and solids, or have a strong petroleum odour. Genuine WG9007380005 Omega 99 (Grease For Disc Brake) includes a tamper‑evident seal and a QR code linking to the certificate of analysis.
