The AB Tools Brake Caliper Bleeding Bleed Nipple Screw offers a durable and precise solution for bleeding brake systems, preventing air and fluid leaks. A key consideration is ensuring the thread size compatibility with your specific brake system.

This refers to the thread size. '3/8"' is the diameter, and '20 BSF' indicates the number of threads per inch (20) and the thread form (BSF - British Standard Fine).
You can use these if your vehicle's brake calipers are designed for a 3/8" x 20 BSF thread size and 6mm brake pipes. Always check your vehicle's specifications before purchasing.
Tighten until snug, with no signs of leakage. Overtightening can strip the threads in the caliper or break the screw. A common torque spec for bleeder screws is around 5-10 Nm, but refer to your vehicle's service manual.
The total length of the thread under the hex head is 8mm.
As they are made of steel, they can be susceptible to rust if exposed to moisture over time. Applying a light coating of anti-seize compound to the threads can help prevent this.
Each pack contains 4 bleeder screws.
Verify the thread size (3/8" x 20 BSF) and ensure the caliper threads are clean and not damaged. Do not force the screw; remove and re-attempt carefully.
Check that the screw is tightened sufficiently (but not overtightened) and that the seal is forming correctly. Ensure the thread length is appropriate for the caliper.
Apply a penetrating lubricant and allow it to soak. Use a well-fitting spanner or socket and apply steady pressure. If it remains seized, professional assistance may be required to avoid caliper damage.
