I agree. For one thing the rivets holding the brake pad to the shoe would have done far greater damage, and likely at some point the outer ring would have broken away from the fins and would have created all kinds of havoc.

When was the last time you worked on brakes? Disk brake pads have never been riveted as far ass I know. And that was a vented rotor, they have no outer ring. The part that's missing looked exactly like the part that's still there. Vented rotors are two seperate flat discs with fins in between, all one cast part.

Guess I'm showing my age. Yeah, you're right - pads are not riveted on. That was "Brake Shoes". Still, it looks like that brake rotor was cut on a grinder. There's no way a person could drive a vehicle like that without catastrophic destruction of the braking system at that location. It'd yank that pad and jam up or break the braking system.

Guess I should have become a coder. I could have handled that one. Right up my alley.

Disk brakes need flat surfaces on both inner and outer rings. The space in-between the rings are the louvers for venting away heat from the brake disk. The one in the picture is clearly modified with the intent to make it look like someone's an idiot who could drive a car to that much damage - and live to tell about it.

no, that is another type of brake disc, one made to bolt to a separate hub. Many high performance , race type disc brake rotors are mad like that, so the high temperatures from braking don't burn out the wheel bearings.

And I have done brake jobs that had the rotor worn though like the original picture. I worked for my father in law that had a used car lot, and some people actually drive the car like that. There is no way that the pad backing plate can get caught in the ribs, the size of the surface area of the pads won't let it. Too many ribs being in contact at one time to let it happen.

 

Well, OK. Learn something new every day. My assumption has always been that disk brakes and their calipers depend on two pads compressing (gripping) the rotor and slowing or stopping the car. I would like to see some pictures showing how exactly a disk brake system can have only one side and a caliper that only applies pressure from one side - and still be effective.

 

There is a very interesting U Tube channel called "Just Drove In" that features some quite unbelievable pieces of junk brought in for repairs that are truly amazing they made it that far. Always good for a few grins and giggles while wasting time. The kinds of things my darling sister that thinks that all you need to buy for a car is gas would do. Other than a ton of ridiculous stickers all over it. As we say in the South, "Bless her soul"!

Your assumption is correct, but it only is that way when a disc brake system is properly maintained. The caliper is contained from rotating when the brakes get applied by a bracket on the spindle and there are two "pins" that connect the caliper to the bracket. If when a brake job is done the pins are not lubricated usually only one side of the caliper is actually doing any thing to stop the disc. And it isn't allowed to let the caliper recenter its self after the brake is released. In my years of doing car work it is the out side pad that wears out before the inside. The inside is where the hydraulic piston is located so when the brake pressure is released and the piston retracts, that pad is more free to move. But the outer one is stuck in place against the rotor due to the friction on un-lubricated pins. So then the outer pad is always rubbing the disc.

It's always amazed me that some people don't listen to the noises a car makes and if they do, it doesn't matter to them.
