How Long Will New Brake Pads Squeak?
3 Answers
How long new brake pads will squeak mainly depends on the type of brake pads, as different types require different break-in periods. Brake Pad Lifespan: Under normal driving conditions, the front brake pads of most vehicles last between 30,000 to 50,000 kilometers, while the rear brake pads can last between 120,000 to 150,000 kilometers. The exact replacement time depends on the wear condition. The mileage specified by manufacturers may vary for different vehicle models. Brake Pad Replacement Tips: When replacing brake pads, it is advisable to choose products from reputable manufacturers. Typically, brake pads produced by reputable manufacturers have clear packaging prints, including license numbers, specified friction coefficients, and execution standards. The packaging box should also contain a certificate of compliance, production batch number, and production date. It is recommended to have new brake pads installed by professionals at a specialized repair shop to avoid errors that could lead to potential safety hazards. Checking Brake Pad Condition: When inspecting brake pads, it is also important to check the wear of the brake discs or drums to ensure sufficient contact area with the brake pads for improved braking performance.
After I got new brake pads installed, that squeaking noise lasted for quite a while and was really annoying. I asked some experienced drivers and mechanic friends, and they said the new brake pads have rough surfaces that need some time to wear in and fit smoothly with the brake rotors. In my experience, the noise lasted about seven or eight days before gradually fading away—since I mainly drive short distances in the city, commuting about 30 kilometers daily. If you drive more or take the highway, where braking is more frequent, the noise might go away faster. However, driving habits matter: if you brake hard often, the noise can get worse and shorten the pads' lifespan, while smooth driving helps speed up the break-in. What I learned is that it's normal for the noise to fade within five to fourteen days. But if it persists beyond two weeks, there might be an installation issue or worn brake rotors, so it’s best to get it checked. Safety first—don’t ignore the noise. If the brakes ever feel unreliable, stop using the car immediately.
From the perspective of automotive maintenance, noise from new brake pads is common, primarily due to the friction surfaces not being properly bedded in. The duration typically lasts about a week, ranging from as short as three days to as long as fourteen days. Factors influencing this include driving frequency and habits: those who commute frequently in urban areas with frequent stops and starts may experience a longer break-in period, while highway driving with less brake usage may shorten it. Additionally, installation quality is crucial; misaligned pads or lack of lubricant can prolong the noise. The condition of the brake rotors also plays a role; if they have grooves, the noise period may increase. It is normal for the noise to disappear within two weeks; if it persists longer or is accompanied by unusual sounds, it may indicate potential issues requiring professional inspection to ensure brake reliability. Regular system checks can prevent more serious problems.
