How often should I replace my brakes? Is there a definitive timeline or specific mileage that one should adhere to when it comes to brake maintenance? Given the critical role brakes play in vehicle safety, it is paramount to consider factors beyond mere odometer readings. Should I be vigilant about their performance in diverse driving conditions that may impact their longevity? For instance, do frequent stops in urban environments or the challenges of hilly terrains necessitate more frequent inspections or replacements? Additionally, how do the materials used in my brake pads and rotors influence their wear and tear? Is it advisable to consult with a certified mechanic to assess the state of my braking system regularly, or can I rely solely on my own observations? Ultimately, what warning signs should alert me to the imminent need for brake replacement before it jeopardizes my safety on the road?
