What Does This Indicator Mean?
The Jetour Red Brake System Warning Light is a critical safety indicator designed to alert the driver of an immediate malfunction or abnormal condition within the primary hydraulic braking system, Electronic Parking Brake (EPB), or Anti-lock Braking System (ABS) module. In Jetour vehicles, such as the X70 or X90 series, this warning light typically illuminates as the universal red exclamation mark inside a circle, flanked by parentheses, or as the word BRAKE. The vehicle’s Body Control Module (BCM) and Electronic Stability Control (ESC) unit continuously monitor hydraulic brake line pressure, brake fluid reservoir levels via a float switch, and the operational status of the electronic parking brake actuators. When the sensor circuit registers critically low brake fluid, a complete failure of the brake pressure differential switch, or an electrical fault in the parking brake clamping mechanism, a dedicated fault flag is sent over the Controller Area Network (CAN) bus, immediately triggering this high-priority red warning on the digital instrument cluster.
Can I Still Drive with This Light On?
No, you cannot and must not drive your Jetour vehicle if this red warning light is illuminated. A red severity rating in automotive engineering denotes a critical system failure that poses an immediate threat to vehicular safety, property, and life. Continuing to drive with an active Red Brake System Warning Light risks catastrophic brake fade, extended stopping distances, or total hydraulic brake failure due to fluid loss or air ingestion within the brake lines. If this light illuminates while operating the vehicle, safely maneuver to the side of the road immediately, engage your hazard lights, and turn off the engine. Towing the vehicle via a flatbed truck to an authorized Jetour service center or a qualified mechanic is the only acceptable course of action.
Common Causes of the Warning
- Low Brake Fluid Level: The master cylinder reservoir has dropped below the minimum fill line, typically caused by natural friction material wear in the brake pads or a hydraulic fluid leak in the calipers, brake lines, or wheel cylinders.
- Electronic Parking Brake (EPB) Fault: A mechanical jam, motor failure, or communication error within the rear dual-caliper EPB actuators prevents the parking brake from fully releasing or seating properly.
- Brake Fluid Level Sensor Failure: The magnetic float switch or electrical wiring harness connected to the brake fluid reservoir cap has short-circuited or failed, falsely reporting a low fluid condition to the instrument cluster.
How to Diagnose and Reset It
Diagnosing the Jetour Red Brake System Warning Light requires a methodical approach starting under the hood. First, ensure the vehicle is parked on level ground and the engine is off before safely opening the hood to visually inspect the brake fluid reservoir. If the fluid level is below the minimum mark, inspect all four wheels, brake hoses, and the master cylinder for signs of active hydraulic leaks. Next, connect an advanced OBD2 diagnostic scanner capable of reading enhanced chassis and body codes to the vehicle’s 16-pin data link connector (DLC) under the dashboard to retrieve specific Diagnostic Trouble Codes (DTCs) stored in the ABS and EPB modules. Utilize a digital multimeter to check continuity and voltage supply at the brake fluid reservoir switch and EPB actuator connectors if no fluid leaks are present. Once the underlying mechanical or electrical root cause is repaired, replenish the system with the manufacturer-specified DOT 4 brake fluid if necessary. The warning light will automatically extinguish once the system parameters return to normal limits and stored fault codes are cleared using the diagnostic scan tool.
