Just rolled into the shop...

Seen at my buddy's tire shop this week... The hat came off without the rest of the rotor, too.

What kind of rotor is that- oh, wait- no way!

how did that not generate so much heat that everything went gooey-kablooie??

I saw something like this at a Midas Muffler shop my buddy worked at like 30 years ago! In that case the owner asked for a "free" brake inspection as the brakes weren't working to well. When one of the mechanics went to pull the car into their shop he almost put it through the storage racks behind the car lifts as the pedal went to the floor. The caliper piston had come out of it's bore due to there being no brake pads and half a rotor. All had been worn away in metal-to-metal contact by the cars owner.

Those parts went on to the "wall of shame" that the shop kept for display to their customers in the waiting room.

that happened to my 91 caprice at 148k on the factory rotors. the friction surfaces were still nice and smooth and in spec, but the vanes rusted away and split it in half. had to fix it in a parking lot. thanks road salt!

That's impressive. As bad as the rust here is I've never seen it eat through the vanes before.

I'm guessing both the caliper and the wheel bearing are screwed now.

So.......new pads then?

99% of Service Advisers: So, you can machine those rotors, right?

I was expecting something about my favorite subreddit.

Ive seen slight worse. Swept area of rotor was completely gone. No vanes no nothing. Only hat and very outter lip of rotor which is not swept had wedged itself in the caliper, was left. Looked like a magical invisible rotor

Should have take a picture with a baseball card rigged to the "spokes."

I have seen that on a Ford HD pickup... brakes were so worn that the pads and backing plates were gone. The Piston was busy machining the rotor into two parts as it too was down to the vanes.. and this was a truck that worked for a lawncare place. It was often full of dirt, mulch, and pulling a trailer full of equipment

Next time you have to do a quick slow down or stop in heavy traffic think about what brakes and tires are on the cars/trucks behind you. Even after 50 years of car repair/service I am still amazed at what is being driven out on the roads. After living/working on east coast with every state requiring yearly auto/truck inspections (twice a year in PA) I moved to major rust zone MN and could not believe the junk allowed to operate on the roads. BTW, it just needs pads.

Seeing this makes me not wanna go drive. Living in a college town I see alot of questionable things just walking in parking lots.

Did you have to mention that? There goes a bunch of time...

Holy crap

Makes me feel marginally better about my truck pulling ever so slightly because the brakes drag on one side

What's so bad?
It's still half there.

Nothing wrong with that rotor. Its just a slotted rotor taken to the extreme.

I just finished working on a Lincoln LS-V8 that had a rear disk a few hours away from being like the one in the OP.

I was going to say it was half gone.

We haven't had twice a year inspections in Pennsylvania for a long, long time. I wish we still did because people can have tires that just pass inspection in April but are totally bald for the winter. They complain about how bad their car is in the snow so they drive really slow and put on their four ways and, eventually, crash. All of that make big traffic jams. berkeleyers.

and in NJ.. all they check is emissions... think about that a moment

Really? Well, it has been over 30 years. Leave it to politicians to change a good practice for more votes. The inspections used to enable us to buy cars/trucks that would not pass inspection at reduced prices. We could do the repairs and drive them or sell them for a profit.

I bought a T-bird for its 460 like that. PO said the car was all rusted out, the front end was shot, the brakes were shot.

Rust was a dime sized hole in the roof. Solid everywhere else.

Front end was a bad rag joint. Tie rods and ball joints were all new.

Brakes was the right inboard pad had somehow fallen out, allowing the caliper piston to grind into the rotor. I rotated the piston 90 degrees and installed a new pad.

Car was in better shape than the car I bought the engine for, so I drove it instead.

The 750 vacuum secondary Holley (ubiquitous 3310) that someone swapped onto the engine got saved when I scrapped the car. (For some stupid reason someone replaced the reliable as gravity Autolite 4300, which had better drivability, better fuel economy, and more airflow) I used it as a diagnostic carb at work for a while and now it exists as the throttle body on my RX-7's engine.
