Description
The Thexton Master Cylinder Bleeder & Plug Kit (849) is a comprehensive automotive tool designed for professionals and home mechanics to service master brake cylinders with precision. It provides the necessary components to perform two critical functions: cleanly bleeding a new or rebuilt master cylinder on a workbench and testing its internal seals for leaks. This ensures that the master cylinder is in proper working order before it is installed on the vehicle, preventing common issues like a spongy brake pedal.
KEY FEATURES AND BENEFITS:
- Versatile Fitment: Includes a full range of aluminum adapters for both SAE and Metric fittings, compatible with a wide variety of vehicles.
- Effective Air Removal: Bleeder adapters and hoses allow thorough bench bleeding, removing all trapped air for a firm brake pedal feel.
- Leak Testing Capability: Plugs isolate the master cylinder for internal seal testing, helping identify faulty units before installation.
- Specific Vehicle Coverage: Includes adapters for newer Ford F-150s to ensure modern vehicle compatibility.

- (2) Metric M14x1.5 adapters
- (4) Check Valve Assemblies
- (4) Bleeder Hoses
- (1) Tubing Holder
- (1) Thread Gauge
HOW TO USE:
- Select the Correct Adapters: Use the thread gauge to match the master cylinder ports with the appropriate SAE or Metric bleeder adapters from the kit.
- Attach the Bleeder Hoses: Thread the correct bleeder adapters into the master cylinder ports and attach a bleeder hose and check valve assembly to each.
- Position for Bleeding: Place the master cylinder securely on a workbench and submerge the hose ends into a container of clean brake fluid.
- Perform the Bleeding Process: Slowly push the master cylinder piston inward and release it to remove trapped air. Repeat until no bubbles appear in the fluid.
- Test for Leaks (Optional): Replace bleeder adapters with plugs, apply pressure to the piston, and check if it holds. A firm piston confirms good internal seals.
