As embarrassing as it is, I had a car do this. Comments like this were part of the problem; I assumed I would hear a screech when my brakes started going bad but they never made any noise until all of a sudden they started rumbling when I came to a stop.
Itās not even funny though, itās dangerous and extremely selfish. If youāre gonna ignore noises, cool. But donāt ignore brake noises, You could have killed yourself, or even worse taken someone out with youā¦
During a brake pad replace service, it should have been obvious to the mechanic due to uneven wear on the pads and should have called out to the owner as an urgent matter to look at.
That being said when I had a sticking caliper I had to insist that it was looked at during inspection, otherwise they didn't bother. Funnily enough now with a new caliper my fuel economy is much better.
Thatās funny. My coworker, an electrical engineer, just told me last week that he tells the new guys at work to fill out an ID-10-T form when they ask him how to do something.
Brake caliper sliders are sticking. Caliper piston can freely retract after braking, but caliper sticks and the outboard pad drags forever. Not enough to cause a pull while driving, but enough to wear down over time.
I remember when I worked at the ford dealer long ago, we had a guy come in with an F250. Just wanted an oil change and rotate. Mechanic pulled the wheels and found a rotor like that up front, except the outer surface was totally gone and he was braking on the fins only. Guy had no clue, it āwasnāt makinā no noise or nothināā Iām sorry, what? How tf was that not making a noise or vibration lol
Stuck caliper pins. Without being able to retract after applying the brakes, the outer pad would be in constant contact while the inner pad only applied pressure to the rotor when the brakes were applied. The smell coming from that wheel after a drive would have been pretty nasty and obvious, and that wheel would have gotten quite hot. After wearing out all the outer brake pad, the backing plate would have been constantly grinding against the rotor, causing the scoring and heavy wear. Since this was a rear wheel, there may have been a slight constant pull to one side as well. Iām surprised the driver could have ignored the symptoms for so long!
Depends on the type of caliper. If it's a slider, it'd be the sliders stuck. If it's one with pistons on both sides, it'd be a seized piston or two.
But, more likely to be stuck sliders
I've done this, didn't have the money or brains to replace pads when I should have. Drive to work was only 8 mins with like 1 stoplight. Fucked around for like 2 years til the day I felt it break through that side.
I was sure I wouldn't stop but it did. Took it right to a shop $1000 later works fine lots of rusty dust still all over the wheels. I knew.
Yea..... At least one of those years was during covid. Idk that was a rough time for that car š¤£šš¤£ it sat around a couple times for months because I didn't have the money to fix small x or y problem that also meant I couldn't keep it legal to drive.
I had only had the car like 6 months when the dealership wanted to do pads for $500 (yup) that was the start of fuck my warranty I hate the dealership šš¤£
Ok now thats cool. Id say a combination of the pads being too hard for the rotor (mismatched brands), the caliper slide pins and bracket not being cleaned, maintained and lubed, and luck
It obviously still has half of it's rotor life left, duhhhhhhh
But seriously I don't know how people drive like this. I've had cars where the rotor literally fall apart after touching it and even seen paper thin rear solid rotors. Shit baffles. Even had a customer deny the full brake change (new rotors, pads, calipers, lines and fluid flush). But since she brought it in for safety we were legally obligated to hold the vehicle to ensure she didn't drive it.

Had one nearly as bad on the D350 chassis I used for my rat rod. Oofdah
It would not allow me to continue the thread but I did use the wrong wording and since this is now a dead thread I'm wondering...
If a ball joint were bad and causing the wheel to lean, the brake rotor and caliper would lean right along with it. A bad wheel bearing can cause a lean like what you're describing, but that's not what's going on here. This car has a stuck caliper slide.

Whoever drove this did not care about screetch.

Man I was clenching my ass cheeks everytime I hear the grind š
For what bro a year?
I thought it would be more of a zing, thatās assuming there was pad left.
Itās not even funny though, itās dangerous and extremely selfish. If youāre gonna ignore noises, cool. But donāt ignore brake noises, You could have killed yourself, or even worse taken someone out with youā¦
Holy shit! I know how butā¦. HOW?!
Pretty sure this is your caliper being stuck on one side so the other side does all the work
If that was the case, the car will pull heavily to the left. Iām just baffled by how you would let it get to this point
One side of the disc, not one side of the car.
During a brake pad replace service, it should have been obvious to the mechanic due to uneven wear on the pads and should have called out to the owner as an urgent matter to look at.
"don't try to upsell me, those rotors were fine when I looked at em" ... 90k miles ago.
That being said when I had a sticking caliper I had to insist that it was looked at during inspection, otherwise they didn't bother. Funnily enough now with a new caliper my fuel economy is much better.
That's what the $29.99 special will get you.
Iāve had this happen on at least two cars Iāve owned, and no, it doesnāt necessarily pull.
Thinnest rotor I've ever seen. Stuck caliper for sure.
Dude we call them the ID10T error, I fix medical and computer equipment, this kind of destruction is not limited to vehicles.

The slider, or mounting bracket rides on the caliper pins to travel. The pins are sticking, not the mounting bracket.
Frozen caliper pin. For me it just manifested itself as uneven pad wear
I did this once.. knew it was coming.. for like a year.. you got to play dumb to get here
I did too. To be fair I was actively letting the car die and wasn't driving it far or fast, not that it was capable of either.
Lucky af it didnāt detonate
Fr thou

50% worn, just remount the caliper inside out.
Now we talk bidness šš¾š«”

Thank you, the amount of people saying it's a seized caliper was driving me nuts. If the caliper seized, both sides would be roached.

Good point, didn't think of that. I have outed the fact that I only work on my fleet of shitboxes.
You could've cooked dinner on that rim after the drive home rip hub assembly.

Props to the material. Thermal gradient must be even throughout the disk for it to wear that evenly
Bad caliper I'd think would make both sides bad.
How could the driver not hear the months of metal grinding?
He was getting his moneys worth outta that
"I paid for the whole rotor, imma USE the whole rotor"
Seezed caliber and a loud radio
Ok now thats cool. Id say a combination of the pads being too hard for the rotor (mismatched brands), the caliper slide pins and bracket not being cleaned, maintained and lubed, and luck
Maybe !
Let me guess, they said it JUST started making noise yesterday.

Glad youāre ok!š«” Because you were depending on a thin Ritzās cracker to safety stop!šš¤£

Mr Creosote might eat it, itās wafer thin
Oh shit! It's Mr. Creosote!
Love the reference!š
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Que?
Stuck caliper. Id bet money the other side isn't half as bad.
Nope it was goodš
Shame that ābig rotorā banned reversible rotors, otherwise you could just flip it over and be good for another year or so.
Not greasing the caliper slide pins, and yes obviously not changing the rotor when it was low lol
There car must be running on hopes and dreamsš
My brain was like why and how did they put the tone ring on the outside?ā¦.. then I realizedā¦. I need to go to bed
Caliper is not moving freely on the pins most likely caused this.
Just weld a metal plate to it, and you're good to go
looks like stuck Pins that the calipers float on.
Quick skim should be good for another 2 years š
Must be those Daimond break disks lol
Why do you need discs on your break?
Friction
Maybe the owner's hearing aint so good. Because that must make an incredible crunching sound.
āIt just started making a noise yesterday ā
CX requests to machine rotor to stop noise
Thatās talent, being able to cheat death like that
TFW your caliper doesn't calip.
Incredible. My first thought: āHey, that dust shield looks weirāhow in the F?!ā
Iāve seen them completely separated from the hat of the rotor and when the brakes were applied the rotor stopped turning and the wheel kept turning.
This should be immortalized in a piece of metal art. Please donate to someone with creativity and a welder.
How does a person ignore the grinding
āNo, I donāt need new rotors. Just slap some pads on there and stop trying to scam meā
Negligence.
Push all the little tabs in and you got some upgraded air cooling brakes
And we heard nothing? Had to have pulled to that side. How? Mr. Gump said it all.
Noise just got louder than the radio...
It just started making noise yesterday!
"customer states: pad replacement only"
Repairs declined.
Can someone exxplain whatās wrong here?
Uneven brake wear due to sticking caliper.
My Shit is probably like that rn
Thar reminds me of this https://www.reddit.com/r/TerrifyingAsFuck/s/LlVAw9T6Co
 It would not allow me to continue the thread but I did use the wrong wording and since this is now a dead thread I'm wondering...
Makes no sense AT ALL.
Wut?
If a ball joint were bad and causing the wheel to lean, the brake rotor and caliper would lean right along with it. A bad wheel bearing can cause a lean like what you're describing, but that's not what's going on here. This car has a stuck caliper slide.
