FRENKIT Front Brake Caliper Slider Pin for 01-05 Honda Civic EP3, 99-06 S2000

Brake Caliper Guide Pins

Caliper guide pins (also called slider pins) are lubricated steel bolts that let the brake caliper slide smoothly in its bracket. This sliding action allows the caliper to clamp evenly on both sides of the brake disc when you press the brake pedal. Each pin sits inside a rubber boot that keeps out moisture and dirt and holds the grease in. Over time, the boots can tear, the grease dries out, and the pins corrode or seize, which causes uneven braking and accelerated wear.

Symptoms that indicate replacement is needed:

• Uneven brake pad wear: one pad (usually the inner) is worn much more than the other, or the pads are tapered
• Vehicle pulling to one side when braking
• Brake drag: the vehicle feels sluggish, or you notice a burning smell after driving
• Excessive heat from one wheel compared to the others after a drive
• Squealing, grinding, or clunking noises from the brakes, or rattling over bumps
• Sticking or binding caliper: the pins don’t slide freely by hand
• Visible corrosion, pitting, or scoring on the pin surface
• Torn, cracked, or missing rubber boots
• Reduced fuel economy caused by constant brake drag
• Brake pedal vibration or a spongy, inconsistent pedal feel

Tip: Pins should be cleaned and re-lubricated with high-temperature silicone brake grease at every pad change. If they are rusted, bent, or worn, or the boots are damaged, replace them (and the boots) rather than reuse them.
