Description
The Thexton Universal Master Cylinder Plug Kit (803P) is a crucial diagnostic tool for automotive professionals and serious home mechanics. It is designed to quickly and accurately determine if a master cylinder is the source of a brake system issue, such as a sinking brake pedal. By allowing you to isolate the master cylinder from the rest of the brake system, you can directly test for internal seal leaks and fluid bypass, eliminating guesswork and saving valuable diagnostic time. This comprehensive kit provides the necessary plugs to service a broad range of vehicles, from domestic to import models.
KEY FEATURES AND BENEFITS:
- Isolate and Test: Allows a technician to isolate the master cylinder from the vehicle's brake lines for accurate testing of internal leaks.
- Comprehensive Plug Selection: Includes 26 machined aluminum plugs in both U.S. and Metric sizes to fit most master cylinder port configurations.
- Efficient Diagnostics: Pinpoints the master cylinder as the source of the problem, preventing unnecessary replacement of other brake components.
- High-Quality Materials: Machined aluminum plugs provide a precise fit and reliable seal during testing.
SPECIFICATIONS:
- Included in the Box: 26 Machined Aluminum Plugs, a Thread Gauge, and User Instructions.
- Plug Sizes Included:
- SAE (U.S.) Sizes: Two of each: 3/8-24, 7/16-24, 9/16-18, 9/16-20, 1/2-20.
- Metric Sizes: Four M10x1.0, four M10x1.25, two M11x1.5, two M12x1.0, two M12x1.5, two M14x1.5, two M13x1.5, and one M10x1.50.
HOW TO USE:
- Safety First: Ensure the vehicle is on a level surface, ignition is off, and wear appropriate safety gear, including gloves and eye protection.
- Disconnect and Plug: Disconnect the brake lines from the master cylinder ports. Using the included thread gauge, select the correct plugs and thread them into the ports hand-tight.
- Apply Pressure: Slowly apply pressure to the brake pedal with the ports plugged, noting how the pedal feels.
- Check for Leaks: A firm pedal indicates a good master cylinder; a slowly sinking pedal indicates internal seal leaks.
- Remove Plugs: Carefully unthread the plugs and reconnect the brake lines after testing.
