Facing disc brake mounts is a critical step in any professional build to ensure perfect component alignment and eliminate creaks. Abbey Bike Tools has released a post mount facing tool for $65 that uses the frame's existing threaded hole as a guide for facing the brake. It is a portable option for home mechanics who want to move toward professional precision without the cost of full shop equipment. The first batch is already sold out, with a restock expected in late October.
In a high end workshop, we typically use heavy, stable equipment to ensure everything is perfectly square. While a smaller, more affordable tool makes the process accessible, there is always a trade off between portability and the absolute stability of a professional rig. It is important to consider whether a tool at this price point can consistently deliver the same results as a $600 professional setup when dealing with stubborn mounts.
Do home mechanics see enough of a benefit in brake setup and alignment to justify investing in a $65 facing tool over standard installation methods?
On a separate note, the matching 3mm socket for this tool is sold separately. I generally believe in having a complete, dedicated kit for every specific task to avoid rounding off fasteners or using the wrong tool for the job.
