Signs I need New Brake Rotors
- High-Pitched Screeching Sound
- Indicates brake pads are completely worn, causing metal calipers to scrape the rotors.
- Likely results in deep grooves in the rotors.
- Squeaky Brakes
- Often caused by brake pad material transferring to the rotor surface.
- Vibrations or Jittery Sensation While Braking
- Suggests warped brake rotors.
- Rotor Thickness:
Mechanics must replace any rotor that falls below the manufacturer’s minimum thickness requirements. - Inspection Timing:
The best time to inspect rotors is during a brake inspection, as it typically requires wheel removal for a clear assessment. - Professional Advice:
A qualified technician, like those at Serra Traverse City, can advise if rotors need immediate attention or if the job can be postponed.
Regular maintenance and timely inspections help ensure your brake system operates safely and efficiently. If you notice any of these symptoms, scheduling a brake inspection promptly is a smart move!
Warp of Brake Rotors
- Glazing from Brake Pad Material
- When brakes are used aggressively or overheated (e.g., from hard braking or towing), the friction material on the brake pads can transfer unevenly onto the rotor.
- This creates high spots on the rotor’s surface, leading to uneven braking forces and the sensation of a “warped” rotor.
- Rotors That Are Too Thin
- As rotors wear down due to regular use or resurfacing during brake service, they lose the ability to properly absorb and dissipate heat.
- Thin rotors overheat more easily, which can lead to warping or uneven wear patterns.
In addition to these causes, improper torque when installing wheels (not using a torque wrench) can also distort the rotor over time due to uneven pressure. Proper maintenance and attention to rotor thickness are crucial for preventing these issues.
