Do rotors get old?
Brake Pad Replacement & Rotor Replacement Like brake pads, brake rotors wear out over time. If they are thinner than the manufacturer’s recommended thickness, then you need to replace your brake rotors immediately. Some vehicles always require new pads and rotors because the rotors cannot be resurfaced.
Why are my brake rotors not coming off?
I have a 2002 Ford Focus which has had a speed-related vibration when I put on the brakes. I figured the front rotors are warped so I bought 2 new rotors and proceeded replace the old ones. I removed the brake calipers and all went well – except I can’t get the old rotor off!!!
When do you replace the rotors on a car?
More often than not, many rotors today are being replaced when the brakes are relined – and some motorists are complaining that new rotors aren’t really necessary.
Can a car rotor have too much runout?
If you see more than the allowed amount of movement in the dial indicator, the rotor and/or hub may have too much runout for smooth braking. Exceptions to this rule are 1997-2002 Chevrolet Malibu, 1997-1999 Olds Cutlass, 1999-2002 Olds Alero and 1999-2002 Pontiac Grand Am models. On these vehicles, GM allows only .0015 inch of lateral runout!
Why are my rotors rusted to the hub?
The rotors were similarly rusted to the hub. I believe that the clearance between the hub and the inner cavity that it fits in is so close that rust essentially welds the rotor to the hub. At first, I tried penetrating oil and a little rapping with a hammer around the hub area. No love.

Is it better to turn rotors or replace them?
This is the correct way to “turn” rotors that need to be machined, and it provides a smooth surface for the new pads. Unfortunately, by turning every rotor that measures up, regardless of need, you lose preconditioned rotor surfaces. Turning a “good” rotor makes it thinner and reduces its ability to absorb and dissipate heat.
How does a disc brake rotor work on a car?
Disc brake rotors are metal discs that work together with the brake pads and calipers to slow the vehicle. Brake rotors bolt directly to the wheel hub, so they spin in direct relation to wheel speed.
