Can You Cut Drilled And Slotted Rotors?

Drilled and slotted rotors can be cut, but it is not recommended. Cutting rotors can cause them to become unbalanced and lead to premature wear. If you must cut your rotors, make sure to have them professionally balanced afterwards.

  • Park your vehicle on a level surface and set the parking brake
  • Loosen the lug nuts on the front wheels using a lug wrench
  • Do not remove them completely
  • Jack up the front of your vehicle and place jack stands under the frame to support it
  • Remove the lug nuts and front wheels
  • Inspect the rotor for cracks, warping or other damage and replace if necessary
  • Place a C-clamp around the outside circumference of the rotor near one of the mounting holes
  • 7Make sure that the jaws of the clamp are touching metal and not plastic or rubber parts of the rotor assembly as this can damage them
  • 8Tighten down the screw on top ofthe C-clamp until it is snug againstthe rotor but does not distort it unduly as this can damage or warpthe rotor

Can Drilled And Slotted Rotors Be Resurfaced?

Drilled and slotted rotors can be resurfaced, but there are a few things to keep in mind. First, the slots will need to be filled in before the rotor can be resurfaced. Second, the drilling may have weakened the structural integrity of the rotor, so it’s important to have it inspected by a qualified mechanic before resurfacing.

How Do You Cut Drilled Rotors?

If your vehicle has drilled rotors, you may be wondering how to go about cutting them. Drilled rotors are not as common as they once were, but they can still be found on some vehicles. Here is a step-by-step guide on how to cut drilled rotors:

1. Jack up the vehicle and remove the wheels. This will give you access to the rotor.

2. Use a caliper wrench to loosen and remove the brake caliper bolts.

You will need to do this so that you can access the rotor.

3. Use a C-clamp or similar tool to compress the brake pads against the rotor. This will give you more room to work with when cutting the rotor.

4a. If you have an angle grinder: Carefully position the blade of the angle grinder on one of the drill holes in the rotor. Slowly start cutting through the hole, being careful not to damage other parts of the rotor or yourself!

Once you have cut through one side of the hole, move onto another hole and repeat until all four sides of all holes have been cut through. You should now have eight “tabs” sticking out from each hole in your rotor – these tabs need to be ground down flush with the surface ofthe rotor using your angle grinder (or a file if necessary).

Be very careful not do damage surrounding areas whilst doing this!

4b . If you don’t have an angle grinder: You can use a hammer and chisel instead (although this method is more likelyto cause damage). Position your chisel at one edge of a drill hole and tap it gently with your hammer until it startsto cut through – be very careful not apply too much pressure or force, as this could shatterthe entire rotor!

Once you’ve startedcutting through one side of each hole,
move onto another side and repeat until all foursides are done.” Use a file (or sandpaper) to smooth off any sharp edges left behind by your cutting – again, take care not damage any other partsoftherotor!

5 . Reassemble everything in reverse order – firstly putthebrakepadsbackinplaceandcompress themwithyourC-clamp(ortoolofchoice), then bolt onthecaliperagainusingyourwrench.

Do Drilled And Slotted Rotors Need to Be Turned?

No, drilled and slotted rotors do not need to be turned. However, it is recommended that you have your rotors checked for thickness periodically. If they become too thin, they may need to be replaced.

How Do You Break in Drilled And Slotted Rotors?

It’s important to know how to properly break in new drilled and slotted rotors. Doing so will ensure that they last as long as possible and perform at their best.

Here are the steps to take:

1. Bed the rotors in gradually. When you first install new rotors, don’t just start driving normally. Instead, bed them in gradually over a period of a few hundred miles.

This process ensures that the pads and rotors seat correctly and form a good bond.

2. Avoid hard braking whenever possible. During the bedding-in process, and for the first few hundred miles after, avoid hard braking whenever possible.

This will help prolong the life of your new rotors.

3. Follow up with a good cleaning.

Are Drilled And Slotted Rotors Good for Daily Driving?

There are many different types of brake rotors on the market today. Two of the most popular choices are drilled and slotted rotors. So, which one is better for daily driving?

Drilled Rotors Drilled rotors have small holes drilled into them. This helps to improve cooling by allowing hot air to escape from the rotor more easily.

The holes also help to remove water and debris from the surface of the rotor, which can improve braking performance in wet conditions. However, drilled rotors are more susceptible to cracking and wear than solid rotors. They also tend to be noisier than other types of brake rotors.

Slotted Rotors Slotted rotors also have slots cut into them, but these are much deeper than the holes on drilled rotors. The slots help to vent hot air from the brakes and also allow water and debris to escape more easily.

This can improve braking performance in both dry and wet conditions. Slotted rotors typically last longer than drilledrotor s since they’re less likely to crack or wear down prematurely. However, they can be noisy, especially when first installed on a vehicle.

So, which type of brake rotor is better for daily driving? It really depends on your personal preferences and driving habits. If you do a lot of stop-and-go driving in city traffic, then slottedrotor s may be a better choice since they’re less likely to overheat and fade (the pads can start to “glaze” if they get too hot).


While drilled and slotted rotors may look cool, there are some potential downsides to using them on your car. For one, they can be more susceptible to cracking and warping than solid rotors.

Additionally, the holes and slots can collect brake dust and debris, which can lead to uneven braking and reduced performance over time.

If you’re considering drilled or slotted rotors for your car, be sure to do your research and weigh the pros and cons carefully before making a decision.
