Brakes are the most essential safety component in a vehicle. If your brake warning lights are on, it means there is a problem with your braking system. In the earlier car models, there was only one brake system warning light – but with new developments and different types of brakes, there are more brake lights to keep an eye on . <\/p>\n\n\n\n

Here\u2019s a complete guide on different brake warning lights and the possible issues that can cause these lights to illuminate. <\/p>\n\n\n\n

DIFFERENT BRAKE SYSTEM WARNING LIGHTS<\/strong><\/h2>\n\n\n\n

There are three different types of brake system warning lights among the car dashboard warning lights<\/a>. Different symptoms in the brake system illuminate the warning lights on the dashboard to let the driver know about the problem. The following are the commonly found brake warning lights and why they turn on:<\/p>\n\n\n\n

Brakes consist of a complete system including brake lines and a master cylinder filled with oil. When you press the brake pedal, it activates the master cylinder to pump the oil to the system to engage brake callipers and stop the vehicle. Now, there is a sensor that detects when the fluid level is low in the brake cylinder and turns the brake fluid warning light on.<\/p>\n\n\n\n

Car brake fluid <\/a>level lowers if there is a leak in the spring system of brakes. After a certain level, the light can turn on as a warning sign to check brake fluids.<\/p>\n\n\n\n

Most modern vehicles have a sensor telling if the parking brakes are engaged or not. Parking brakes affect the transmission if the parking brake is engaged while driving the car. This sensor will turn on the parking brake warning light to let the driver know and disengage the car emergency brake at the same moment.<\/p>\n\n\n\n

Although it is more of a reminder light, it can also be a warning that your car emergency brake<\/a> requires servicing.<\/p>\n\n\n\n

BRAKE PAD WEAR WARNING LIGHT<\/strong><\/h3>\n\n\n\n
