What do you lube slack adjusters with?

Slack adjusters are typically lubricated with a high-quality lithium-based grease. This type of grease provides good adhesion and resistance to moisture, helping to prevent corrosion and wear. It's important to apply the lubricant through the grease fitting, ensuring that it adequately penetrates the moving parts of the adjuster. Regular lubrication helps maintain the proper function and longevity of the slack adjusters.
