Brake Fluid Safety & Compatibility Standards

Safety Warning: Brake fluid has strong water absorption. After absorbing water, the boiling point will drop significantly, directly leading to brake failure, rear-end collisions, vehicle loss of control and other traffic accident risks; the industry's general replacement cycle is 2 years, and the status needs to be checked regularly.

Brake Fluid Type Dry Boiling Point Wet Boiling Point Core Application Description
DOT3 205℃ (401℉) 140℃ (284℉) The most common type on the market, installed in most household vehicles
DOT4 230℃ (446℉) 155℃ (311℉) Higher boiling point, mostly used in high-performance vehicles such as racing cars and police cars
DOT5.1 270℃ (518℉) 190℃ (374℉) Glycol-based, cannot be mixed with DOT5 silicone-based brake fluid

Core Functions

High-Sensitivity Probe

Equipped with high-quality advanced sensors, fast response speed and high detection sensitivity; integrates four core features: fast response, high-sensitivity sensing, flashlight lighting, and replaceable probe. The metal hose can be bent arbitrarily to adapt to different scenario detection.

Wide-Range Compatibility Detection

Fully compatible with DOT3, DOT4, and DOT5.1 three mainstream brake fluids, covering most passenger vehicles on the market.

Excessive Standard Audible & Visual Alarm

When the water content of the brake fluid exceeds the safety standard, it will automatically trigger a buzzer alarm. The honeycomb-shaped sound hole on the back ensures clear volume, intuitively prompting the user to replace the brake fluid.

Accurate Water Content Grading Display

The LCD screen intuitively presents the test results, and the brake fluid quality is determined according to the oil type. The determination criteria are as follows:

  • DOT3: Water content ≤1% is high purity, >3% needs immediate replacement
  • DOT4: Water content ≤2% is qualified, >3% needs immediate replacement
  • DOT5.1: Water content ≤2% is qualified, ≥4% needs immediate replacement

Official Tip: To ensure braking performance, it is recommended to plan the replacement of brake fluid in advance when the oil water content reaches 2%.

High-Resolution HD Screen

Equipped with a high-resolution LCD display, it can clearly display the detection values and results whether in a dark environment at night or in direct sunlight during the day.

Panel Function Layout

Front: LCD display, mode selection key, LCD light switch key, power key, function key
Other parts of the body: Universal universal probe, flashlight switch, detection probe

Product Design & Details

  • Non-slip Body: The body has a non-slip texture, fits the hand shape, and is easy to operate with one hand
  • Replaceable Battery Design: Easy to disassemble and assemble, energy saving and power saving
  • Replaceable Probe: Consumables can be replaced separately, reducing long-term use costs
  • Strong Compatibility: The universal flexible probe can be bent to adapt to the detection of brake fluid reservoirs of different models and positions
