The Thexton Master Cylinder Brake Bleeder and Plug Kit, No. 849, includes long-lasting aluminum adapters for SAE and metric fittings. Bleeder adapters fit most makes and models to remove air from the master cylinder. The kit also includes the new Ford F-150’s adapters. The plugs enable the technician to isolate the master cylinder from other brake components. The plugs also test whether the internal seals are leaking or in good condition. The kit includes bleeder and plug adapters for the following: SAE: two 3/8-24, two 7/16-24, two 9/16-18, two 9/16-20, and two 1/2-20.
