Sealey Brake Fluid Tester - Boil Test - VS0275

It is recommended to test your brake fluid at least annually, or more frequently if you notice any changes in brake pedal feel or if the vehicle has been exposed to high humidity conditions.

A low boiling point directly indicates a high level of water contamination in the brake fluid. This means the fluid is more likely to boil under braking conditions, leading to a spongy pedal and reduced braking effectiveness.

Yes, this tester is compatible with DOT 5 and DOT 5.1 specification fluids. However, it's crucial to follow the specific instructions for testing silicone-based fluids if they differ from standard glycol-based fluids.

The built-in heater raises the brake fluid sample to its actual boiling point. This controlled heating process allows the tester to accurately measure the boiling point, which is the key indicator of water content.

No, this tester measures the boiling point of the brake fluid. While a lower boiling point correlates with higher water content, the device provides the boiling point temperature as the primary result, not a direct water percentage.

After use, empty any remaining fluid and clean the sample cup and probe area thoroughly with a clean, lint-free cloth. If necessary, use a small amount of appropriate cleaning solvent, ensuring all residues are removed before storing.

The Sealey VS0275 requires a 12V DC power supply. It typically comes with a power lead designed to connect to a vehicle's accessory socket or a suitable 12V battery.

Verify the 12V DC power source is functioning correctly. Ensure the power lead is securely connected to both the tester and the power source. Check the fuse if applicable.

Ensure the sample cup and testing probe are clean and free from residue. Verify the brake fluid sample is fresh and representative of the system fluid. Allow the tester's heater element to stabilize before reading.

Check the 12V power supply voltage. Ensure the display screen is clean and not obscured. If the issue persists, contact the manufacturer for support.

Ensure enough fluid was added to cover the heating element and probe adequately. Check that the tester lid is properly sealed to prevent vapor escape. Refer to the operating instructions for minimum fluid levels.
