What kind of signs are indicative of brake system issues?

Unusual vibrations when driving can indicate brake system issues, as such vibrations may result from imbalances or malfunctions in the brake components. When the brake pads or rotors are worn out or improperly aligned, they can cause the brake system to function erratically, leading to noticeable vibrations. This can signal that the brakes are not applying evenly or that there is a more significant underlying issue, warranting further inspection.

While low coolant levels and air leaks might affect other systems within the vehicle, they are not direct indicators of brake system problems. Low coolant levels mainly pertain to the engine cooling system, and air leaks are typically associated with the air supply system, which may impact the brakes in some configurations but are not standalone indicators of brake concerns. Therefore, focusing on unusual vibrations is the best way to identify potential brake system issues.
