How to Apply Dielectric Grease on Brake Caliper Pins

• First, remove the caliper pins from the caliper housing.
• Thoroughly clean the caliper pins with brake cleaner to remove any dirt or debris.
• Apply a thin layer of this grease to the caliper pins. Be sure to apply the grease to the entire length of the pins.
• Reinsert the caliper pins into the caliper housing.
• Apply a small amount of this grease to the rubber boots that cover the caliper pins. This will help to prevent the rubber from drying out and cracking.
• Reinstall the caliper onto the rotor and tighten the bolts to the manufacturer’s specifications.

It’s important to note that this grease should only be used on the caliper pins and not on the brake pads or rotors. Using it on brake pads or rotors can cause them to become contaminated and reduce their effectiveness.

Additionally, it’s important to use high-temperature grease that can withstand the high temperatures generated by the brakes. Permatex Ceramic Extreme Brake Parts Lubricant is a good choice for this purpose.

By following these steps, you can ensure that your brake caliper pins are properly lubricated and protected from corrosion, allowing your brakes to operate effectively and safely.

Advantages of Using Dielectric Grease on Brake Caliper Pins

Prevents Corrosion and Rust

It forms a protective barrier that prevents corrosion and rust from forming on the pins. This is important because corrosion and rust can cause the pins to stick, which can result in poor braking performance and safety issues.
