Many other brake pad wear indicator lights on your dashboard will illuminate with ignition and switch off a few seconds later. However, some ABS brake pad wear indicator lights will only extinguish after reaching 10 to 15mph, the speed at which the system becomes activated.
Can I still ride with my ABS brake pad wear indicator light on?
If the brake pad wear indicator light remains on at higher speeds, there’s something wrong with your ABS system, but thankfully this doesn’t affect your normal brakes.
You’ll still be able to ride, but take extra care – particularly in adverse weather conditions
Anyone who off-roads as a hobby knows that four-wheel drive is a must-have. Unlike two-wheel drive cars, vehicles equipped with four-wheel drive (4WD) have a transfer case that takes the power from the engine and sends it to the front and rear wheels.
Most four-wheel-drive vehicles also have a low and high range depending on the situation. Even though there is a button or shifter that is used to activate a four-wheel drive, automakers include a brake pad wear indicator light on the dash to let the driver know what setting is being used.
What the four-wheel-drive indicator brake pad wear indicator light means
When you engage the four-wheel drive, a corresponding brake pad wear indicator light is illuminated on the dash. Vehicles with multiple gear ranges will also indicate what range has been selected. High and low are commonly abbreviated too respectively.
Some vehicles may only have an indicator for low range as the high range is the default. Refer to the manual of your vehicle for specific information on your four-wheel-drive system.
Newer model vehicles have started using electronics to control the four-wheel drive. Some of these electronically controlled systems have a 4×4 automatic mode. This mode keeps the vehicle in two-wheel drive mode for most of the time until extra traction is necessary. The computer monitors the wheel’s rotational speeds and if it notices any slipping, it will send the power to all four wheels to keep the car moving.
Vehicles that have four-wheel drive systems tend to have a separate brake pad wear indicator light to indicate an issue with the system. Usually labeled when this brake pad wear indicator light comes on, a code will be stored in the memory to help identify any issues. Depending on the problem, the four-wheel-drive may be disabled temporarily. Sometimes if you used a four-wheel drive for a while, the computer may think that the transfer case lubricated properly.
If your Service brake pad wear indicator light turns on, try engaging the different gear ranges and driving around a little to move the oil around. Hopefully, the next time you start the engine, the brake pad wear indicator light will be off.
Is it safe to drive with the four-wheel-drive indicator brake pad wear indicator lights on?
Using four-wheel drive in slippery situations makes a huge difference to the vehicle’s drive ability. You should never engage four-wheel drive on dry pavement.
The four-wheel-drive requirements some slippage to occur between the front and rear wheels which is why perfect for gravel, snow, and sand.
On dry pavement, the grip prevents any slipping from happening, and enabling four-wheel drive will over stress the drivetrain. Vehicles equipped with automatic four-wheel drive switch between the modes on demand, so you need to worry about switching it yourself.
If your service brake pad wear indicator light is on or if your four-wheel-drive system seems to be working properly, ask one of our certified technicians to help you diagnose any problems.
