How thick should rear rotors be?
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.
What is minimum brake rotor thickness?
Brake rotors are marked with a “minimum thickness” on the casting (usually 2 mm to 3 mm less than the new rotor thickness). Rotors should be replaced before they reach this minimum thickness and should not be “turned” (machine refinished) below this. Brake pulsation is not caused by warping of the disc.
How thick should disc rotors be?
Disc brake rotors usually last so long that many people treat them as ‘fit and forget’ components. However, manufacturers provide minimum thicknesses for their rotors. Shimano recommends that its rotors, which start out 1.8mm thick, should be replaced when the braking surface has been reduced to 1.5mm.
What is the minimum rear brake rotor thickness?
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). The rotor’s minimum thickness tells you the minimum operational level of your rotor.
How do you tell if your rotor needs replaced?
It could represent four signs that it’s time to replace your brake rotors.
- Vibrating Steering Wheel. If you feel pulsing in the brake pedal and vibration in the steering wheel when you slow down, your rotors could be signaling trouble.
- Intermittent Screeching.
- Blue Coloration.
- Excessive Wear Over Time.
How do you tell if your rotors are too thin?
When a rotor is too thin, it overheats and warps, leading to an annoying vibration or pedal pulsation. When rotors were thicker, they could take the wear from the brake pads, be machined and still have enough metal left to dissipate the heat.
How do I know my rotor size?
How to check your rotor size:
- Start by checking the vendor’s catalog fitment notes.
- Call your local OEM dealer and ask for the original rotor sizes or OEM rotor/pads part numbers based on your vehicle’s VIN number (VIN# is referenced in your ownership papers).
What’s the minimum thickness for a disc brake?
Disc Brake Rotor Minimum Thickness (also known as Scrap Thickness) is the minimum safe working thickness of a rotor at which it must be replaced. Risk: Continued operation at or below Rotor Minimum Thickness can lead to Brake system failure. As the rotor reaches its minimum thickness, the braking distance increases, sometimes up to 4 meters.
How can I check the thickness of my brake rotors?
The rotor thickness should be measured using a micrometer. The thickness should also be gauged before and after the rotors have been turned, to check for proper thickness or depth specification. 1. Raise the front or rear of the vehicle, depending on the rotors that need to be measured, and secure the vehicle with the jack stand.
When do you need to replace your brake rotors?
The strength of the rotor is also reduced, leading to more risks of cracking or not braking. Whenever you check the brake pads, it’s essential to check the rotor thickness as well. If its thickness is below the minimum specification and it cannot be resurfaced, then you need to replace the brake rotors immediately.
What’s the difference between DTV and disc thickness?
Disc Thickness Variation, DTV is a variation in thickness of the disc rotor braking surfaces as it rotates on the axle… Remind your customers of the importance of regular brake inspections. Most drivers will only have their brakes inspected when they run…
