The braking system is vital to safe driving. That’s why maintaining all components including the brake rotors is crucial.
The main reason why brake rotors need to be replaced is simple wear and tear. Every time you step on the brake pedal, these rotors are subject to damage due to friction. With repeated application, the metal material is slowly worn away over time. Most manufacturers recommend swapping them out for a new set every time you replace the brake pads. This is more of a “two birds one stone†tactic to avoid potential problems later on and to save you time at the mechanic.
Another reason why brake rotors need to be changed is warping. As these discs are being used, they are constantly being heated and cooled. With time, the tolerance for this process is reached and the metal begins to distort. This deformation commonly occurs with towing or going uphill frequently. Finally, cracks may also be grounds for a transition of parts.
So, what signs should you look for to know if your brake rotors are bad? Squeaking as you step on the corresponding pedal is one, and pulsation is another.
