Brake Caliper Thread Repair Kit - M12 x 1.5mm - Neilsen - CT3893

This kit is specifically designed to repair M12 x 1.5mm threads.

You will need a power drill and potentially a torque wrench for reassembling the brake caliper.

With practice, a single thread repair can often be completed in 30-60 minutes.

The kit is most effective on stripped or cross-threaded holes. Severely damaged or corroded caliper housings may require professional assessment or replacement of the component.

A stepped drill bit allows for precise enlargement of the hole in stages, ensuring the correct diameter for the tap and insert without over-drilling.

The inserts are designed for a single permanent repair of the damaged thread.

It is best stored in the original case provided to keep all parts organized and protected from dirt and damage.

Ensure the drill is set to the correct speed and that adequate pressure is applied. Check that the drill bit is sharp and properly aligned with the center of the existing hole. Use cutting fluid if necessary.

Ensure the hole has been drilled to the correct size and that the tap is started perfectly straight. Back the tap out periodically to clear metal shavings. Use cutting fluid.

Verify that the hole was drilled and tapped correctly according to the kit's specifications. Ensure no debris is present in the new threads or on the insert. The insert locator should be used for proper guidance.

This could indicate the hole was not drilled to the correct size or the tap was not used properly. Ensure the insert is fully seated and that the locking mechanism (if applicable to the specific insert type) has engaged. If the repair is compromised, the process may need to be redone or a larger repair solution considered.
