What is Brake Caliper Grease?

Brake caliper lubricant, or brake caliper grease, is designed to lubricate your vehicle's brake calipers, brake pads and hardware, and the caliper guide pins to help prevent friction and noise. Brake grease is typically 100% silicone-based and is made to withstand the heat caused by braking. When servicing the brake system on your vehicle, brake caliper lubricant must be used at every contact point, except the brake pad or rotor friction surfaces, to ensure that the brake system functions at its best.

Where to Grease the Brake System

Various places on the braking system require brake grease. When you step on the brake pedal, the brake pads are compressed by the brake caliper to make contact with the spinning brake disc, resulting in friction that slows the vehicle.

  • Brake caliper guide pins are responsible for guiding the brake pads to meet the brake disc at the correct angle, and allow the caliper to slide during compression through the brake caliper bracket. If the brake caliper guide pins are not properly lubricated, you may notice symptoms such as a sticking brake caliper, premature wear, unusual braking noises, and reduced braking performance.
  • Brake hardware makes contact with the ears of the brake pads in some applications, and are often made of stainless steel. Replacing this hardware during a brake repair can help minimize friction, but ensuring it is properly greased can prevent noise and sticking over time.
  • Brake caliper pistons receive brake fluid pressure, causing the piston to extend and compress the brake pads against the rotor. Greasing the end of the brake caliper piston and the contact surface on the caliper behind the outer brake pad can help minimize noise due to contact between the brake pad shims and the caliper or piston.
  • Brake rotors are installed over the hub assembly, and are held in place by the wheels and lug nuts to ensure they stay aligned properly with the calipers and brake pads. Using brake grease between the hub assembly and the inner surface of the brake rotor hat can help prevent the rotor from sticking to the hub, allowing for simpler rotor removal in the future.

    • Why Do I Need to Grease My Brake Parts?

    Failing to grease parts of the brake system during reassembly can lead to noise and poor brake system performance. In some cases, it may also be necessary to grease brake parts again before a complete brake service, especially if you often drive in dusty environments that could contaminate the brake grease and prevent it from performing as it should. If your brake caliper sticks due to a dry guide pin, it may compress the pads unevenly, causing premature or abnormal wear. Poor braking or uneven wear on your pads are both signs that your caliper pins may not be properly lubricated. Squeaking or other minor noises from your brakes may also be attributed to brake pads or other parts sticking due to a lack of brake grease. It's important to use 100% silicone grease designed specifically for lubricating brakes, as regular grease may overheat and collect more dirt, limiting its lubricating abilities.
