When Should You Turn Brake Rotors?
Jan 20, · This video describes different types of brake rotors and methods for resurfacing them using a brake lathe. Apr 23, · The brake rotors are just as important as the brake pads – they work in tandem to stop your vehicle suddenly. Brake rotors are crucial to stopping your vehicle, are available in several different types, and have important impacts on the inner mechanism of your car. Turning rotors ensures that your brake rotors are working at an optimal level.
Knowing when to turn brake rotors is important as it can save you a substantial amount of money and ensure your car remains safe to drive. Turning brake rotors is a term that is used to describe machining, or lathing, brake rotors down to remove the excess brake material from your pads and to prevent warping and grinding, thus extending the life of your brake pads. Turning a rotor allows for smooth braking action and creates less heat then those that are warped. Typically you want to have your rotors turned every other brake change.
This ensures that they remain free of debris and do not warp. Regular brake wear and hot spots can often cause your rotors to become warped and having them turned will ensure that they last as long as possible before having to be replaced.
If your rotor surface is smooth there is generally no need to have them turned. If, however, you have warping, or rough spots they should be turned, or replaced if need be. This is easily detected if you have a solid, non-pulsing braking action when you press down on the pedal.
Those with the money may wish to have their rotors turned every time they have their pads done. This will ensure the maximum amount of life to the brake pads. Realistically rotors can only be turned so much before they need to be replaced. Always make sure you consult with your mechanic prior to any work in order to ensure your rotors need to be turned or replaced. When opting to change your brake rotors, you should always go for the ones with the best performance, and there are a lot of brake rotor manufacturers who can cater to your needs.
One of the best and well known brands is Brembo. This manufacturer is tried and tested, and even used by the high-end cars such as Porsche, Audi and Mercedes-Benz. You can also go for Raybestos, which has a wide range of rotors for your application. These rotors do not warp due to heat during hard driving. They also keep the temperature down, increasing the stopping power.
Brake rotor manufacturers have put a lot of time and effort into these rotors. If you have a pretty old car and this is the first time you are changing its brake rotors, a brake rotor puller may be necessary. This is due to the fact that your brake rotor is probably stuck from being there since the car was bought many years ago. You may have a difficult time in pulling out the old rotor, so you will need mechanical assistance already in order to achieve this. These pullers come in several sizes, depending on the size of your rotors.
The puller effectively pulls the rotor by evenly applying how to be a distributor of nestle products force to the whole rotor while pushing on something that is fixed on how to make hot air balloon out of tissue paper car, such as the axle.
This is what the brake rotor puller is for. Racing brake rotors definitely have a performance upgrade and can help you stop your car faster. There are 3 types of racing rotors. They are slotted, cross-drilled and slotted, and cross-drilled.
All perform better than the stock rotors that come in normal sedans. These rotors greatly help in dissipating heat, making the brakes more effective.
They also help channeling water away during wet situations such as rain and flood. Tests show that if you upgrade to racing rotors, there will be a 37 percent increase in stopping power, more or less. These racing brake rotors can therefore handle more speed from your car and make it stop faster when needed.
When installing brake rotorsassuming that the old rotor has been removed, the first tool that you will need is a socket wrench set. Fitting the new rotor where the old one used to be, would also require a screwdriver to wedge the screw or clip holding the how to bead native american style in place. You then need a C-clamp to push the piston within the caliper in order to open it up and fit it easily over the rotor.
You then use the wrenches again to return the brake caliper and secure it by putting back the bolts that held it in place.
Installing what is 5 of 14000 rotors is not that hard, and all you need are the right tools. Saved Vehicles 0 Saved Searches 0. Cars Direct. Home Car Repair Brake Repair.

Feb 22, · If the rotor measurements are safe to turn, the process begins by mounting the rotor into the lathe. Once secured, a tip runs across the surface, removing warps and restoring the plate into the basic shape and size. Once you finish, you can also run the machine on the outer edges of the disc to remove lips and cracks. Jan 27, · Knowing when to turn brake rotors is important as it can save you a substantial amount of money and ensure your car remains safe to drive. Turning brake rotors is a term that is used to describe machining, or lathing, brake rotors down to remove the excess brake material from your pads and to prevent warping and grinding, thus extending the life of your brake pads. Aug 14, · Unlike pads, however, your rotors don't have wear indicators, so it can be hard to know when it's time to replace them. Back in the day, it made sense to resurface rotors whenever pads were replaced. Resurfacing rotors, also known as machining or turning rotors, is performed by a mechanic who shaves a thin amount of metal off of each side.
My regular mechanic says turning rotors is needed as well. Question-is it necessary to turn rotors if we are not yet down to metal? If you replace rotors, and then turn them, what you are doing is shaving perfectly good metal off of a brand new part and therefore significantly shortening its life. If you turn rotors without replacing them, what you are doing is making the rotor thinner and therefore more prone to warp, which is why you turned them in the first place. In short: I just replace rotors.
Rotors are made entirely of metal. The PADS are not. They will be too thin afterward and prone to warping. If the rotors need work, replace them. Check your owners manual. Thanks, all. The philosophy behind turning rotors is to remove any uneven surface to provide the longest life for your new pads. If they feel the rotors can be turned do it, it will provide the best braking. DOWN to 8mm??? If you like to wear your pads down to the metal, at that point you will probably need to replace the rotors anyway.
Grinding the brake pad backing plate into the rotor will destroy it in very short order. This then causes brake noise. Flat rate manuals often give about. There are 2 ways of turning rotors also. One is the quick and easy method.
The other is the much slower and correct method. Many people who turn rotors believe the best method is to set the lathe on FAST, dial in about. This is not the correct method. Sometimes I will find new drums or rotors in the box with the kind of machining you are talking about, ok This is especially bad with drums and I will often machine.
The first test drive with outrageous vibration and shoe slap was enough to make me do this before installing any new drums that had a rough or threaded finish. I side with the dealer. The reason you want a certain amount of thickness in your rotors is that the rotors absorb most of the heat created during braking, and dispels that heat into the air while you are not braking.
Rotors are heat sinks. Brake pads are composed of materials that tend not to absorb heat. Depending on what kind of roads you travel, this can either mean very little to you or become a life and death situation. If you tend to brake very little, and for short periods, on relatively flat roads, rotor thickness is not so big a deal. If you routinely travel very steep roads downhill and need to use lower gears and need to brake frequently and for long periods, you want nice thick rotors and pads.
Very hot rotors cannot provide enough friction to slow a vehicle on a steep decline. I get it that you mean by your question, do you need to turn or replace the rotors if they are not scored but are getting thin.
The answer is no to turning the rotors. The answer is yes to replacing them if they are thin. Since you are asking about rear brakes, one thing to check is whether your emergency brake is holding the car in place on an incline while the car is in neutral. You need that to pass inspection. The other more important reason you want to replace them if they are too thin is that the rear brakes need to work just as well as the front brakes in order to ensure even braking front and back, which prevents the front brakes from engaging the ABS too soon during sharp or wet braking.
In most cars, the rear rotors are the easist to replace, but you have AWD, so I guess that the replacement will be as much work for you as the front rotors would be. Rear brakes need to work in concert with the front brakes. It still had the original rotors my wife brakes carefully!
Ask your mechanic to inspect your rotors including measuring the thickness to compare to new. If the rotors are not significantly worn, are not deeply grooved, your brakes do not pulsate when applied at high and low speeds, the swept surfaces on the rotors are not reduced by winter salt corrosion and the vehicle stops without veering to one side, you can run with your old rotors.
Shallow rotor grooves are harmless but take it a easy at first to let new pads bed into the shape of lightly grooved rotors. It is the policy of pro mechanics to either turn or replace rotors whether needed or not to reduce the possibility of a comeback complaint. I have the original rotors on a car with well over , miles. That is only one example but demonstrates that rotors can be reused without machining them. Turn rotors?
I agree but then again I use a lot of aftermarket parts and do the work myself. The difference in price is just too little to try and squeeze a little more life out of them, only to end up paying to replace them soon anyway. Nobody turns rotors anymore. First, the cost of turning a rotor almost equals the cost of a new replacement rotor.
Second, as mentioned turning rotors makes them thinner making them more suseptable to warping. I change my pads when the friction material is about the same thickness as the metal backing.
