What kind of grease is used for brake guide pins?

[LincolnRose]

Brake guide pins typically use calcium-based grease (butter) with certain water resistance. Since the guide pins are exposed, and vehicles often drive through water during rainy seasons, calcium-based grease has water resistance that prevents it from being washed away, ensuring the braking system functions properly. Engine oil is strictly prohibited for brake caliper guide pins because it can easily be washed away by water, leading to loss of lubrication and potential seizing of the guide pins, resulting in brake failure. Here is more information about brake guide pins: 1. Maintenance: Brake system maintenance helps prevent high temperatures, rust, corrosion, and ensures lubrication. 2. Consequences of abnormal brake guide pins: (1) If the guide pins of the brake caliper are poorly lubricated or stuck, abnormal braking may occur, leading to ineffective braking or dragging brakes. (2) If the guide plates at both ends of the brake pads oxidize or rust, it will affect the sliding movement of the brake pads.
