Can slotted and slotted rotors be machined?
Content
The rotation of the rotors increases the braking efficiency and extends the service life. You need to constantly evaluate the condition of your rotors to prevent accidents caused by faulty rotors.
Yes, you can turn and grind slotted and holed rotors to improve braking performance. The rotation of the old rotors allows them to create enough friction for the braking system. However, you can't reuse rotors forever. Replace them every 50,000-70,000 miles.
I'll go into more detail below.
Getting Started - Can you turn slotted and slotted rotors?
Yes, you can turn slotted and slotted rotors. However, most people find this task challenging as it requires precision and experience to properly machine ported and slotted rotors. With precision and sufficient know-how, you can get the job done safely.
However, the rotor must not be deformed, rusted, damaged or deformed. Otherwise, the rotation of the rotor will be useless. If your rotors are warped or rusty, seek the help of a professional rotor mechanic. They will evaluate and replace the rotor if possible.
Make sure you change or rotate the rotors whenever you install new pads. The rotors with the brake pads installed also fit correctly.
The process is simple and the following steps will teach you how to turn the rotors safely.
For the steps below, you will need access to a lathe.
Step 1. Set the brake machine to the lowest setting to prevent vibration.
Step 2. Install the rotor on the brake machine.
Step 3. Start the lathe. Do this at a lower setting to avoid damaging the rotors. The brake lathe will cut the rotors precisely so that they fit well on the pads.
Step 4. Fix everything else in the appropriate places. That's it, the rotors are ready to go.
Benefits of turning or grinding rotors with holes and slots
There are different opinions about turning or grinding rotors with drilled holes and slots. Thus, you may wonder if it is profitable to turn them. There are many reasons why you should sharpen or grind rotors. Let's go through some:
1. Improved performance
The rotation of drilled and splined rotors results in higher efficiency. If your rotors are faulty and you have never machined them before, refinishing them will greatly improve their performance.
Older rotors fail or stop functioning completely because they cannot generate the same amount of heat and friction when the brake pedals are pressed. Thus, you will not be able to apply the brakes smoothly, and if you use such rotors for a long time, they will abruptly stop working and cause accidents. You don't want this, so try to float or turn the rotors when you notice problems.
Spinning them (drilled and slotted rotors) helps them regain their ability to generate maximum friction. The brakes will work well and you won't need to buy new rotors. You will save on purchase, maintenance or installation.
2. Longer service life
The first thing to evaluate when the brakes fail or stop working are the brake rotors. As mentioned above, damaged rotors greatly affect brake performance.
You can also consult an expert to check the condition of your rotors if you don't know where to start. They will be able to tell you if the rotors need to be replaced or not.
You can then decide whether to sharpen or grind slotted and holed rotors. Do not process rotors that are damaged above the cutoff level.
Of course, if the rotors are new, replacement is not required. Simply tune them up to increase their lifespan. You can ask your mechanic how long or how many times you should grind your perforated and slotted rotors to increase their life expectancy.
3. Significant savings
Maintenance and installation costs will skyrocket if you replace the rotors every time the brakes fail.
Grinding or turning slotted discs saves you the unnecessary expense of buying new brake discs. Slotted road rotors; frequent exchange leads to bankruptcy and makes car ownership unprofitable. In addition, changing the rotors each time reduces the intensity of friction, which leads to additional costs. (1)
Generally, drilled and slotted rotors are more cost effective to turn than to buy new ones.
F.A.Q.
How often should I turn or grind drilled and slotted rotors?
Rotors should be rotated from time to time for optimal brake performance. How often exactly? In my opinion, do this every time you notice the slightest problem in the brake system. You can also do this whenever you have your car inspected, in the garage or at home.
How often should I replace perforated and slotted rotors and brake pads?
Of experts it is recommended to replace the brake pads between 10,000-20,000 and 50,000-70,000 miles. For slotted rotors, replace them every 2-XNUMX miles. In this way, your braking system will be at an optimal level, which will prevent the risk of its failure. Sudden failure is dangerous and can lead to accidents. (XNUMX)
