How To Remove A Stuck Rotor (Step-by-Step Guide)
Removing stubborn rotors can be an uphill battle if there ’ s a lot of corrosion and corrode. however, with some fortune, a bit of hammering in specific locations will be adequate to pry the two pieces free .
Follow these six steps to unstick your brake rotor :
Before we get started, it ’ mho significant to point out that if you notice rust on certain components like your brake pads and shoes, have them replaced immediately. Rust can get between the braking plate friction material and induce brake failure .
Note: This job can take respective hours and requires some specialist tools, like a propane flashlight or acetylene torch and a rotor puller, depending on the level of corrode and corrosion present. additionally, if you ’ re working on a rear rotor, ensure the parking brake international relations and security network ’ triiodothyronine engaged .
It ’ randomness besides great if you have some technical know-how to avoid damaging other bracken components. As a result, it may be better to let professional mechanics handle the tax for you .
With that said, once you have the car jacked up and the steering wheel removed, you can follow these steps to dislodge your stubborn rotors :
Step 1: Remove The Brake Caliper From The Bracket
There should be two rotor bolts, one located near the top of the caliper bracket, and the other close to the bottom. This will loosen the caliper and provide entree to the brake pads. Remove the pads and set them aside safely .
Step 2: Remove The Caliper Plate
After having disconnected and safely tucked the caliper away, you need to remove the caliper denture. This involves removing a match of bolts located at the back of the caliper bracket. These bolts go through the caliper bracket and connect to the bicycle hub .
sometimes these bolts are held in place with Loctite and may require a little extra campaign to dislodge .
Note: Before removing the brake magnetic disk, there may be a rotor screw or two on the rotor face. You must remove each rotor screw before attempting to dislodge the brake magnetic disk. If a screw has rusted in its screw hole, you may need an affect driver to dislodge it .
Slot the head of the affect driver into the head of the screw and hit the other end of the impact driver. Try and turn the screw as you do so, and with a bite of luck, it ’ ll come free .
Step 3: Temporarily Reattach The Lug Nuts
It ’ second at this point where the bracken rotor should just slide off the wheel.
however, since that international relations and security network ’ t the case, we need to break the corrode .
Before doing that, it ’ s a good estimate to reattach a lugsail en or two temporarily. You good need to screw them on adequate to stop the rotor from coming off and falling on person ’ s foot while removing the corrode .
Doing so will besides ensure no accidental wrong to the threads, which can warp the wheel stud .
Step 4: Remove The Rust
now, you need to remove the corrode .
For this, you ’ ll probably start with a hammer .
about any hammer will work, such as a :
- rubber mallet
- dead blow hammer
- ball-pein hammer
- standard claw hammer
- small sledge hammer.
Some note that using a metallic malleus is more effective because it creates more vibrations, but this can damage the rotor if you ’ ra hitting it directly .
You can then start by hammering in between each lug nut. This is crucial because if you ’ ra performing repairs and not a substitution, hitting the rotor itself can break it, separating it from the bicycle hat .
often, giving it a few taps around the wheel hub is enough to pry the brake rotor off .
Step 5: Grab Some Extra Equipment
If hammering hasn ’ triiodothyronine done the trick, you ’ ll need a backup design.
For this, you ’ ll need some extra parts :
- Two hex bolts
- Two washers
- Two nuts
- Two wrenches
Step 6: Insert The Bolts Into The Threaded Holes At The Back Of The Rotor
If you ’ ra lucky, there might be a thread hole or two on the back of the brake disk. These threaded holes serve no early purpose than to help remove a perplex rotor. Slot a bolt with a washer through each weave hole and secure them with the nuts .
then, with one wrench attached to the crackpot, use the other wrench to tighten the rigidly. then, make sure to switch between the two bolts, tightening them evenly .
If you do this enough times, alternating between the rotor bolts and the brake phonograph record should just pop off .
5 Tips To Help Free A Stuck Rotor
If the above steps seaport ’ t helped free your rusted rotors, there are a couple of other methods available :
Tip #1: Rotate The Rotor
You can try loosening the bolts you installed in the dash hole behind the rotor, putting the cable car in achromatic, and releasing the parking brake. You can then rotate the disk rotor about 45° before tightening the bolt again .
Applying the force out to a different separate of the rotor might besides be what ’ mho needed to break it spare. You might need to rotate the rotor a few times to find out .
Tip #2: Use Penetrative Lubricant
acute lubricant like PB Blaster or Liquid Wrench can be a major asset in your toolbox. By applying a generous sum on the steering wheel hub and the buttocks of the rotor, the lubricant can help dislodge any rust or corrosion .
After giving the lubricant some time to take impression, you ’ ll probably need to hit the hat a few more times .
If you ’ re facing an adamant screw, feel free to use some penetrative lubricant on the cheat trap .
Tip #3: Use A Puller
You ’ ll need a big enough rotor puller to grip around the back of your corrode rotors. There should be an pitting on the center of the rotor face. Using this indentation to secure the puller ’ s center bolt, you can then lock the chew the fat onto the rear of the rotor .
After applying some anoint to the center abscond, you can then begin tightening the puller. If the rotor still doesn ’ t stir, hitting the puller ’ mho center field thunderbolt with a forge can help .
Tip #4: Apply Heat
If the stick brake rotor still hasn ’ metric ton dislodged, you may need to start applying heat with a propane blowtorch. Applying heat to the areas in between the stuff testis on the brake hat may be what ’ randomness needed to ultimately dislodge the stick rotor .
Tip #5: Use A Breaker Bar
If you ’ re desperate to get your rusted rotors off, you might need to consider using a breaker bar and some leverage .
If opting for his method acting, take some extra precautions. Using this much leverage can round out the bolt, and then you ’ re in a worse invest than when you began .
You ’ ll need a one-foot circuit breaker banish and a deceiver bar. then, just slot the goal of the surf on the bolt lead and slot the deceiver barricade over the surf barroom. Make certain to slide the deceiver legal profession all the room down, so you don ’ metric ton bend the breaker bar .
then, gradually start applying atmospheric pressure until the bolt begins to come loose. You should then be able to remove it using merely the circuit breaker stripe .
If you ’ ve tried all the above methods and however have no luck, you can constantly cut the rotor off with an angle grinder. Of course, this will work only if you ’ re installing a brand new rotor and not repairing previous rotors .
now that we know how to remove a stick rotor, let ’ s expect at preventing it from happening again in the future .
How To Prevent A Stuck Rotor In Future
No matchless wants to go through all that employment again, particularly if it ’ south evitable. It ’ south frequently a time-consuming and exhausting occupation, requiring a good amount of attempt and some specific tools. And even then, the most stubborn rotors may take a blend of all methods before finally dislodging .
adjacent fourth dimension you have your brake rotor repaired or replaced, make sure you do the adopt :
1. Clean The Rust And Corrosion
first, ensure you clean any rust and corrosion around the wheel dot. You can do this with a electrify brush or even a wire brush drill attachment. see you ’ re thorough in cleaning the sides and tops of the steering wheel hub since this is where it will rust the most .
2. Apply Some Grease
then, you can ask the mechanic to put some lubricant like insulator dirt on the wheel hub and the rear of the wheel rotor. This is fantastic for preventing the two metals from corroding together in the future.

With constant exposure to the elements, rust and corrosion can cause the bracken rotor to weld to the wheel hub. If you ’ re in a pinch with a lodge bracken rotor and unable to dislodge the two, your best bet is to arrange for a master automobile mechanic to examine the issue .
Trying to separate the hub from the rotor face may require specialist tools. Some technical know-how can besides go a farseeing means as you ’ re going to encounter other substantive components, such as the brake calipers .
When in doubt, don ’ t stress.
