Understanding Brake Caliper Bolts

Guide Bolts (Sliding Pins)
Guide bolts, also known as sliding pins, are essential components that allow the brake caliper to slide smoothly when the brakes are applied. These bolts are designed with a smooth surface and are typically coated with a special lubricant. They enable the caliper to move freely, ensuring even pressure distribution across the brake pad and rotor for optimal braking performance.
Mounting Bolts
Mounting bolts are responsible for securing the brake caliper bracket to the steering knuckle or suspension component. These high-strength bolts are designed to withstand extreme forces and vibrations while keeping the caliper assembly firmly in place. They are typically made from hardened steel and require specific torque specifications during installation.
Bleeder Bolts
Bleeder bolts, also called bleeder screws, are small valves located on the brake caliper that allow air to be purged from the brake system. These specialized bolts feature a small channel through which brake fluid and air can pass during the bleeding process. Properly functioning bleeder bolts are crucial for maintaining a hydraulic brake system free of air bubbles.
Bridge Bolts
Bridge bolts connect the two halves of a split-type brake caliper. These bolts ensure the caliper housing remains properly aligned and maintains its structural integrity under braking forces. They are typically high-strength fasteners that require precise torque specifications during assembly.
Pad Retaining Bolts
Pad retaining bolts secure the brake pads within the caliper housing. These bolts prevent the pads from rattling or moving unnecessarily while allowing for easy pad replacement when needed. They often include anti-rattle features and may come with special clips or springs to enhance stability.
Note: All brake caliper bolts are critical safety components and should always be replaced with manufacturer-specified parts. Proper torque specifications must be followed during installation to ensure safe and effective brake system operation.
