Common Causes of Worn Rotors
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.
Why do my rotors keep warping?
The brake rotors withstand a lot of heat during the process of braking, and need to dissipate this heat quickly so that the brake pads will be able to be pressed down again. Because of this mass amount of heat,
the surface of the brake rotors can become uneven over time
, which is often referred to as warping.
Why do my rotors keep going bad?
rotors go
bad from overheating
which is caused by many factors. rear shoes or pads out of adjustment. all of these by themselves can cause your issue. maybe another shop with a sharp brake guy can help you.
How long do rotors last on average?
Your rotors are one of the most durable parts of your car, but the above factors can shorten their lifespan. Expect your rotors to last anywhere from
30,000-70,000 miles
depending on the above factors.
Why do I always need new rotors?
The most complete brake service includes fully replacing brake pads and rotors, which gives you better stopping power and more fade resistance. Like brake pads, brake rotors wear out over time. … Some vehicles always require new pads and rotors
because the rotors cannot be resurfaced.
What are the signs of bad rotors?
- VIBRATION. When rotors are warped or very worn, the contact between it and the brake pad can be imperfect. …
- NOISE. Worn brakes are noisy and persistent squealing or squeaking is a sure sign of problems. …
- VISIBLE DAMAGE. …
- STOPPING DISTANCE. …
- WILL I NEED TO GET THE ROTORS REPLACED?
Do my rotors really need to be replaced?
Most likely, your brake rotors
will require resurfacing or replacing roughly every other brake job
. When a brake rotor wears unevenly, or grooves are worn into it, or corrosion develops on its surface, one remedy is to have it resurfaced.
How do I stop my rotors from warping?

Will turning rotors fix warp?
Can You Fix Warped Brake Rotors? Depending on how warped your rotors are, a
mechanic may be able to straighten them
. The process of “fixing” brake rotors is called turning or resurfacing. Brake rotor resurfacing involves scraping down the warped metal to achieve a smooth surface.
Do cheap rotors warp easier?
Rotor Thickness
Some auto parts stores have thinner rotors to keep the cost down which is not to OEM specifications. Thinner rotors = less material = less resistant to heat =
more prone to warp
.
Is it OK to put new brake pads on old rotors?
If new brake pads are put onto a vehicle with damaged rotors,
the pad won’t properly contact the rotor surface
, reducing the vehicle’s stopping ability. Deep grooves that have developed in a worn rotor will act as a hole-puncher or shredder and damage the pad material as it is pressed against the rotor.
Should I replace all 4 rotors?
Although it is recommended by
Ford
to replace all four wheel brakes at the same time for safety, your idea should be OK. If you decide to get them replaced, consider enlisting a certified mobile mechanic who can service your brake pads and rotors at your own convenience.
How expensive is it to replace rotors?
Rotors cost
between $30 and $75 each
. Higher-quality rotors like Duralast Gold, which feature a coated hat and edge and are designed to outperform your vehicle’s original equipment, usually cost a little more. Labor at a shop to replace rotors and pads is approximately $150 to $200 per axle.
How often should rotors be replaced?
As a general rule, you should get your brake pads replaced every 10,000 to 20,000 miles to keep wear to a minimum. When it comes to your rotors, you have a bit longer. Your rotors should be replaced
between 50,000 and 70,000 miles
to keep your brakes in peak health.
What happens if you put new pads on bad rotors?
If new brake pads are put onto a vehicle with damaged rotors,
the pad will not properly contact the rotor surface
which will reduce the vehicle’s stopping ability. Deep grooves that have developed in a worn rotor will act as a hole-puncher or shredder and damage the pad material as it is pressed against the rotor.
What happens if you drive on bad rotors?
If you suspect you have warped rotors or your brakes are failing, it is important that you avoid driving your vehicle and contact a mechanic right away. Driving with warped rotors potentially
will result in a brake system failure
, which can cause injury to yourself and those around you.
