5. Installation (Operating Instructions)
This kit is designed to repair existing stripped bleeder screw threads. The process involves preparing the damaged hole to accept the new brass insert.
IMPORTANT: The specific drill bit and tap sizes required for this repair are dependent on the original bleeder screw size and the caliper material. These are NOT included in this kit. It is crucial to consult your vehicle's service manual or a professional mechanic to determine the correct drill and tap sizes for your application before proceeding.
- Neteja la zona: Thoroughly clean the area around the stripped bleeder screw hole on the brake caliper using brake cleaner to remove any dirt, rust, or debris.
- Remove Damaged Bleeder Screw: If any part of the old bleeder screw remains, carefully extract it. If the screw is broken off flush, you may need to drill it out.
- Perforar el forat: Using the appropriate drill bit size (determined from your service manual), carefully drill out the stripped threads. Ensure the hole is straight and centered.
- Tap the Hole: Using the correct tap size (determined from your service manual), carefully tap new threads into the drilled hole. This will create threads for the brass insert adapter. Use cutting fluid during tapping to ease the process and ensure clean threads.
- Clean New Threads: Clean the newly tapped threads thoroughly to remove any metal shavings. Use compressed air and brake cleaner, ensuring no debris enters the caliper's internal passages.
- Install Brass Insert Adapter: Apply a small amount of thread lubricant or sealant (if desired) to the external threads of the brass insert adapter. Carefully thread the brass insert adapter into the newly tapped hole in the caliper. Tighten it securely, but do not overtighten, as this can damage the new threads or the caliper.
- Install New Bleeder Screw: Thread the new bleeder screw (provided in the kit) into the brass insert adapter. Do not tighten it fully yet.
- Bleed the Brake System: With the new bleeder screw installed, proceed to bleed the brake system according to your vehicle manufacturer's specifications. This typically involves opening the bleeder screw, having an assistant depress the brake pedal, closing the bleeder screw, and then releasing the brake pedal. Repeat this process until no air bubbles are visible in the brake fluid exiting the bleeder hose.
