The Guide Sleeve, brake caliper (8930014) restores smooth caliper movement and ensures even pad pressure during braking. Replacing worn sleeves prevents drag, noise, and uneven pad wear. Use Porza’s smart search to find the correct kit.
A brake caliper guide sleeve is a cylindrical component installed within the caliper bracket that houses and supports the guide pin or guide bolt. Its function is to ensure smooth and precise sliding movement of the caliper during braking. By maintaining alignment and reducing friction, the guide sleeve helps ensure even brake pad wear and consistent braking performance.
Key specifications include inner and outer diameter, length, and material composition. Guide sleeves are often made from metal alloys or high-performance polymers designed to withstand high temperatures (typically 150–200°C or more) and mechanical stress. Some designs include low-friction coatings or integrated bushings to improve movement and reduce wear. Tight tolerances are essential to ensure proper fit and smooth operation.
Replacement is necessary when there are signs of wear, corrosion, deformation, or when the caliper movement becomes restricted. Symptoms may include uneven brake pad wear, noise, or sticking calipers. Guide sleeves are often replaced during brake service or caliper overhaul to restore proper function.
Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the guide sleeve matches your specific brake caliper and bracket dimensions, reducing the risk of incorrect fitment.
