This 100% synthetic lubricant contains real ceramic solids for extreme performance under the most critical braking conditions. A purple, environmentally friendly, non-melting formula, this premium lubricant is our longest lasting, most temperature resistant way to silence brake noise such as squealing and chattering; also effective in preventing long bolt and sleeve seizing and galling. Excellent on rolling and sliding surfaces operating in wet or dry conditions from -65°F to 3000°F (-54°C to 1648°C). This product assures that critical brake parts remain lubricated throughout brake pad life. Resistant to corrosion and contaminants, it will not wash out. It is compatible with internal/external brake rubber and plastic hardware, including ethylene-propylene rubber.
