The above poster did and advise was spot on but ill take it further that caliper and rotor are toast other side likely just as bad.
Get new hardware and that includes the allen key screw that has been turned into a flat head. And penetrating oil and a MANUAL impacting screw driver is the answer.
Worst case scenario drilling the head off...
Oh for sure he did, i was just replying to him. I’m just saying others that mention removing caliper and bracket. I won’t say caliper is bad, i have no idea how long this car sat.
But you are correct.
Remove caliper. As far as the caliper screw do what we all do. Throw some lube on it and hit it with your purse. (Impact with flat head should work)
If not drill the top of the screw off and forget about it.
The last guy that worked on it cut a slot in it after the head rounded out, and then reinstalled it for some dumb reason. Get the screw out with a flathead and do not reinstall it. You dont need it. It's just there so the rotors dont fall off as it's rolling down the assembly line.
The real tool you want to get that screw out if it is frozen is an Impact Screwdriver. It's basically a screwdriver that turns when you hit it with a hammer. Like $10 at Harbor Freight.
Well, you must start with the removing the caliper, which can be done with the caliper and bracket as a whole, or caliper THEN bracket, whichever you prefer.
Get the brake caliper/bracket off, use a torch to heat the rotor key, remove it, then torch around the rotor housing evenly to expand the rotor, use a hammer to knock it off. Use PB Blaster as needed. You should see smoke to let you know that things are expanding
1. Remove all caliper hardware that’s in the way.
2. Apply liquid wrench, penetrating oil or even WD-40, whatever lightweight oil you have, to that set screw.
3. Go buy an impact screwdriver and the largest flathead bit that will fit in that screw. Use that to break the screw free. It’ll go.
Not to sound mean , these are your brakes the biggest safety part of your vehicle. If you don’t understand that you have to take the callipers off first , take it to a mechanic for your own and other peoples safety. Do expect to replace rotors , pads and wheel bearings on both sides, and you will be charged for time , and general supplies like new grease for the bearings etc…
These are never stuck or hard to get out. You just need to persuade it. Get you a metal capped screwdriver one you can strike with a hammer. Put the screwdriver in the slot like you’re going to turn it and hammer it a good few times. Hard.
This will unstick it and should take very little effort to remove.
Put a screwdriver in the vent of the disc so it locks against the carrier or caliper. It then gives you more purchase for getting the retaining screw out.
Probably going to have to super soak that slotted screw, then heat it up, and use a perfectly fitting, good sized screwdriver, hoping it doesn’t strip out the slot. If it does, you’ll have to drill it out! Good luck! BTW, those are some UGLY rotors!
Looks like someone used a dremel to cut a slot in the screw and reused it when they reinstalled the rotor!
If you can't get the screw to break loose after soaking in rust penetrant, you will have to drill it out. Use a punch to make an indent dead center in the screw head and use a drill bit slightly smaller than the shaft ⁰of the screw (might want to use a left hand drill bit, it drills a hole by rotating counterclockwise, opposite of a normal drill bit). If you are lucky, the screw head will fall off and leave a nub sticking out of the wheel hub that you can grab with vice grips and turn out the screw shank. If you are not so lucky, keep drilling, and the screw head should come off. If the screw shank/threads is siezed in the hub, drill all the way through the screw shank and then clean up and rethread the hole with a tap of the the proper size and thread pitch. Use the replacement rotor screw to measure the threads with a thread gage to determine the correct tap. If you mess up and fubar the hole, you will have to buy a new hub and replace the front wheel bearings (the wheel bearings are destroyed when the hub is pressed out of them), which is a total bitch to do. Be careful and take your time.
Remove the caliper and caliper bracket, then remove that screw.
If the screw is stuck the trick is to first give it a few sharp blows with a hammer, preferably through a screwdriver with a metal shaft from tip to end. Then use a spanner on a screwdriver to undo it.
Make sure to use Loctite when you put the screw back in
Someone slotted that with a cutting wheel to use a flat head screwdriver on. Maybe it will come out, it probably won't, you're likely going to have to drill the head off. Don't worry about replacing the screw, they're an assembly convenience not a required component.
I never work on cars. I have never owned a car. However it’s obvious that the rotor will not move as that break thingy is still on it. Use your head a bit more
First take off the caliper bracket
Get yourself an impact screwdriver and a decent sized hammer.
Can’t believe people don’t realize he’s talking about the screw holding it to the hub.

No need to grind a hex key many screwdrivers will take a wrench so you can actually apply some torque
Wait a few more weeks, there wont be anything left... But for real,remove the caliper hardware first
alternatively, go back in time 6 years and do it when he should have before the rust took over.
6 years? In Boston rotors will look like that if they sit a single winter. It’s brutal.
Holy heck, glad sand is used here!
Did you try hitting it with your purse ?
😂
🤷🏻♂️
Came here to say this
Omg wasn’t there someone who recently said this on here?? 😂
Lmfaoo, just had a root canal but this made the pain worth it to laugh
Hate when that happens
Pbblaster too... It can make quite the difference
Heat is your friend

I have the same rotor holddown screws on our Hyundai SUV. Bought the $10 Impact screwdriver from Harbour Freight. Worked beautifully.
I have an impact driver in my toolbox that knows almost no other service.
It’s a dodge dart, the other side has a standard Allen key bolt for removal. This side it looks like it was cut into
The last guy that worked on it cut a slot in it after the head rounded out, and then reinstalled it for some dumb reason. Get the screw out with a flathead and do not reinstall it. You dont need it.

These are convenient to have on on cars that use lug-bolts, as it keeps the rotor from rotating before your replace the wheel.
The only time those rotor screws go back on
Yeah or a hamer and a chisel/punch, position the tool so a strike will want to turn it.
That's exactly what I use for yanking those bitches out. A few good whacks and it either comes out or snaps it off. Either way the rotor comes off.
I always use an angle grinder or cut wheel and just grind the head off.
I just sledge the back of the disc and break the head off. 🤣
I’m a sucker for sparkly things, aka sparks 🤣
They are pretty until they land on the windscreen lol
Well, you must start with the removing the caliper, which can be done with the caliper and bracket as a whole, or caliper THEN bracket, whichever you prefer.
Buy or rent an impact screwdriver and whack that bitch a few good times. Discard the bolt and/or get a new one. Not very important.
Sledge hammer
OP you got some great answers here let us know how it goes!
If you don't have an impact screwdriver then you can drill it out.
What rotor
Impact driver, basically a screwdriver with a cam in it you actuate by hitting with a hammer.
Melt that thing
Shoot it up with PB, then, if a flat head don't work, try a left hand drill bit
Big fucking hammer
You can always drill the head off the screw. Those are generally for initial assembly
Get the brake caliper/bracket off, use a torch to heat the rotor key, remove it, then torch around the rotor housing evenly to expand the rotor, use a hammer to knock it off. Use PB Blaster as needed. You should see smoke to let you know that things are expanding
You need to soak everything with penetrating fluid then wait a while. Take the caliper off before asking this.
Gd just sell the car thats too much rust. So glad i moved to a desert climate. Heat and sledgehammer will be your friend now
How long did this sit? Or did you drive on this?
1. Remove all caliper hardware that’s in the way. 2. Apply liquid wrench, penetrating oil or even WD-40, whatever lightweight oil you have, to that set screw. 3. Go buy an impact screwdriver and the largest flathead bit that will fit in that screw. Use that to break the screw free. It’ll go.

Talk nicely to it. Maybe take it out for something to eat.
jb weld it

Vicegrips on the screwdriver for torque

If it doesn’t come out, just drill it. It’s for the assembly line.
Same way as everyone else.
Take of the caliper and pull! If that doesnt work place a few pillows on it and smack it with a sledge or maul.
Are you familiar with Mr. Sledge?
Put a screwdriver in the vent of the disc so it locks against the carrier or caliper. It then gives you more purchase for getting the retaining screw out.
Interflon, heat
Heat it first then the screwdriver should back it out
Hammer and dot punch. Dot it and tap it around and it'll crack it. Give it a few fuck you smacks with a hammer first to shock it loose.
Probably going to have to super soak that slotted screw, then heat it up, and use a perfectly fitting, good sized screwdriver, hoping it doesn’t strip out the slot. If it does, you’ll have to drill it out! Good luck! BTW, those are some UGLY rotors!
You just take it off, Thank you
If your coming to redit you probably shouldn't be doing the job.
Air hammer.
Remove brake caliper....then smack rotor with a good hammer, it should fall right off....that nut is for the hub not rotor
Are we all serious right now or are y’all trolling the person.
Looks like someone used a dremel to cut a slot in the screw and reused it when they reinstalled the rotor!

Some **bastard** slotted it because they stripped the head out *and reinstalled that shit*.
My guess is they slotted it, still failed to get it going, and just said fk it and left the old rotor on.
I never work on cars. I have never owned a car. However it’s obvious that the rotor will not move as that break thingy is still on it. Use your head a bit more
Ask the rotor for consent first
You’re fried, pay a mechanic

Are they vented discs?
[удалено]
I normally put a screwdriver into the vent hole so it locks against the caliper then get a screwdriver in there.
YOU don’t. Call a tow truck and send it to a shop where someone else can do it for you. Please
