Brake lines are metal hardlines present on almost every contemporary car. They function as the braking system's pipes, which is powered by hydraulic pressure. The brake lines transport braking fluid from the master cylinder to the wheels, passing through flexible brake hoses and into the callipers or wheel cylinders of the vehicle.
To endure high pressures and exposure to the environment, most brake lines are composed of steel. They may, however, develop issues with time.
Any issues with the brake lines get to be a problem with the braking system, which becomes a safety concern for the vehicle and must be repaired or replaced before your next MOT testing service to avoid a failure of the MOT test.
