What is the minimum rotor thickness?
Yes there is a minimum recommended rotor thickness, and it varies from brand to brand. Magura’s minimum recommended rotor thickness is 1.7mm. At that thickness, Magura recommends replacing them for several reasons, one being reduced heat stability.
How many mm should brake rotors be?
The standard solid rotor is 12mm (0.472 inches) thick. It should not be ground to less than 10.5mm (0.413 inches). The standard vented rotor is 20mm (0.787 inches) thick and should be ground to no less than 18.5mm (0.728 inches).
Does the size of the rotor matter?
You can exchange brake pads, experimenting with different material compounds for feel and durability, but rotor size has a much more significant influence on absolute brake performance. The more heat your brake rotors can absorb, the longer they’ll retain stopping power, without fading.
Why are my front rotors so big?
The front rotor is bigger because you CAN brake more with the front before losing traction. The rear rotor is smaller because a whole lot of extra braking force is just going to make the wheel lock up anyway, so a bigger rotor would just be a waste.
Are bigger rotors better?
Larger rotors have a greater mass and allow for greater storage of heat. This is good because if there is a greater capacity for heat in the rotors, your brake pads and hose fluid can stay at operation temperatures.
Are thicker rotors better?
Nowadays, brake rotors come with a thinner thickness than before to reduce weight and costs. That’s why the rotors get damaged easily. It is recommended to replace both rotors at the same time, even if one still works as the difference in rotor thickness can result in the brakes pulling towards one side.
How do you tell if your rotor is warped?
If you notice your steering wheel or brake pedal wobble when you apply the brakes to slow down or stop, chances are your rotors are warped. If the warp isn’t too bad, you might not really notice the shaking. If the warp is serious, you’ll definitely feel the vibration.
