Product Overview
The Calibration Instrument for Brake Testers is a universal calibration device designed for verifying the accuracy and performance of various types of brake testing equipment, including:

Roller Brake Testers

Plate Brake Testers

Deceleration (Road) Brake Testers

This calibration instrument simulates known braking forces and loads to ensure that the measurement systems (sensors, electronics, and software) of the tester produce reliable and traceable results. It typically includes mechanical loading systems, force meters, standard weight dummies, and alignment tools.

Key Features:

Compatible with multi-type brake testers (roller, plate, deceleration)

Mechanical or hydraulic force simulation structure

High-precision force sensor or torque meter (accuracy ≤ ±1%)

Adjustable mounting and alignment fixtures

Traceable calibration certificate from a metrology authority (optional)

How to Use
1. Preparation

Ensure the brake tester is clean, functional, and set to calibration or maintenance mode.

Place warning signs or barriers to prevent unintended use during calibration.

2. Install the Calibration Instrument

For Roller Brake Testers: Mount the calibration lever or torque arm onto the roller shaft.

For Plate Testers: Place the calibration force sensor or weighted load on the test plate.

For Deceleration Testers: Use the dynamic simulator to apply reference braking force.

3. Apply Known Force

Use the calibration device to apply a known force or torque (e.g., 1,000 N or 2,000 Nm) to the brake system.

Record the brake tester’s reading and compare it with the actual applied value from the calibration instrument.

4. Compare and Adjust

Calculate the error or deviation.

If the deviation exceeds allowed tolerance (e.g., ±3%), adjust the tester’s internal calibration parameters (software scaling, sensor offset, etc.).

Repeat the test until the measured values match the reference values.

Why Calibration Is Necessary
1. Ensure Brake Test Accuracy
Accurate brake force measurement is critical for evaluating vehicle safety. Without proper calibration, the tester may under- or over-report braking power, leading to incorrect assessments.

2. Comply with Legal and Technical Standards
National and international standards (e.g., GB21861, ISO 21069, EU 2014/45) require periodic calibration of all brake testers to remain legally valid for vehicle inspection.

3. Detect Sensor Drift or Mechanical Wear
Over time, sensors and mechanical components may degrade. Calibration helps identify such changes and prevent undetected errors.

4. Provide Traceable and Auditable Results
For inspection centers and commercial garages, calibration records provide traceable evidence of compliance and reliability during audits or certification processes.
