When to replace your rotors
WHAT ARE ROTORS?
A key part of your vehicle’s brake system, rotors are the large metal discs that are inside of each wheel. Found on disc brakes, the rotor is attached to the wheel by the vehicle’s axle.
Rotors are shaped flat-bottomed bowl piece that sits smoothly between the pads and caliper
HOW DO ROTORS WORKS?
When brakes are applied, calipers squeeze the brake pad against the rotor to create heat and friction. This converts kinetic energy into thermal energy- which the rotors can absorb and dissipate to slow the vehicle.
Fun-Fact: Rotors can heat up to to 1,000 degrees Fahrenheit. During normal street use, brake rotors and pads normally won’t see temperatures climb past 200 degrees Celsius, or 392 degrees Fahrenheit. However, track days are a different story, with temperatures potentially reaching 1,000 degrees Fahrenheit as the brakes are called upon more often and more aggressively.
DO ROTORS WEAR DOWN?
A new rotor has a smooth and even surface. As the brake pad makes contact with the even rotor, you’ll enjoy smooth braking performance. Over time, your rotors can lose their smooth finish. Worn rotors result in increased stopping distances and diminished braking performance.
SIGNS OF WORN ROTORS
Rotors are durable, but like other parts on your vehicle, they need to be replaced periodically. Driving on damaged rotors is dangerous; it can lead to increased stopping distances and a loss of braking power. If you notice any of these symptoms as you drive, it’s time to make an appointment with your mechanic:
- Vibration when braking
- Squeaking, grinding or squealing noises when braking
- Grooves worn into the rotor
COMMON CAUSES OF WORN ROTORS
-SUDDEN STOPS
Panic or emergency braking at high speeds can cause rotor wear. The friction from the brake pad grabbing the rotor can cause high enough heat to result in wear. If you know you are a heavy, frequent stopper, we suggest consider a brake upgrade. Our brake upgrade will help you vehicle handle those stops better and reduce wear.
-RIDING THE BRAKE
Constantly hitting your brakes can results in a buildup of excessive heat that may lead to grooves and warping of your rotors. When driving down a hill consider switching to a lower gear rather than riding your brakes on your way down.
-WORN BRAKE PADS
Driving too long on worn brake pads can cause rotor damage. As the brake pad wears down, the metal becomes exposed leading to metal-on-metal contact when you apply the brakes. This is sound like a loud grinding/scrubbing sound and will cause irreparable damage to your rotors which means in most cases, they will need to be replaced.
