I have seen the same problem on motorcycles. It took a month for it to show like this one did. But it was not from a clamp. Someone didnt adjust the rear master cylinder play. So the rear brake was always dragging. Once the brake fluid turned to vapor. It locked causing what we see in that picture. It even happen to me on one of my Ducati's I let a student adjust my brakes. I was on 680 with a locked rear brake that was on fire. I had to cut the brake line to get it to release as the vapor was holding it at that point.
I had to replace the caliper, wheel bearings, seals, rotor and the brake line. It had been worked on a week before this all happen.
Its possable its been on there a while.

I say use the parts dept. But stay away from sales and service.

the bubbles travel up and go far so its a bother to bleed it


i have taken the line off before

but it was for my aftermarket 4 pot BBK there was a huge lip on rotor and i couldnt get the pads pushed back enough

great minds think alike you and i

Bleeding for pads isnt necessary, you dont even have to remove the line from the caliper.

You say that like you know what happened. You dont know what happened. We have not gotten the entire story from the OP. I know more than most people here who have posted about this situation and I am waiting to see if we will get a truthful answer from the OP about the amount of time and or miles drived until this happened. Also, as Gagan has said, if this were to have happened like the OP stated, when his wheel loked up his car would have turned, violently, to the left, wheels do not lock up at speeds he is talking about while the car stays travelling in a straight line. Also, I find it very difficult to believe he did not smell the caliper or rotor burning, that is a very strong unpleasant odor that if I smelled near my car I would check immediately to be sure nothing is wrong, which he has stated he did not do.

Where did the OP say his rear wheel locked? Think about it for a second - if the wheel LOCKED then the brake would not be able to generate the heat that it did. If there were pressure on the brake line then in normal driving, one would not notice this, and the brake on that wheel would not get normal pressure - hence the rusty rotor. When the driver does a panic stop, it's a burst of pressure which could overwhelm the clamp and let the pressure past to the caliper, however could be strong enough to keep enough pressure to generate the heat needed, over time, to cook the rotor and caliper.

I agree that there is no reason to do anything like this just for doing pads, but then I have seen some seriously weird **** come out of quite a few shops I have taken cars to for service in the Bay Area, including a dealer (not this one).

I do not know the real story obviously, just playing devil's advocate here and not sure why some are jumping to conclusions like this. Personally, if I wanted to set fire to a specific caliper for photos - I wouldn't really know how to do that.

well he got it replaced at Auto HQ... so who evers fault it was, it over now..

awesome reason to get steel braided hoses... can't be pressed like that

Again, it never says the wheel locked. He says "the brake stayed locked" but I think he meant "clamped" as again, there needs to be TONS of friction to make that much heat. The rotor would not be red hot like that if the brake and wheel had locked. Also, if he had locked a rear wheel like that, as Gagan said, he would have experienced shock oversteer along the lines of if the handbrake had been pulled. IMHO the red rotor is plenty of evidence that the wheel did not lock, but there was a good amount of constant abnormal pressure, after the panic stop, on the line which caused the friction needed to deep fry the rotor.

If he were travelling at speed on the freeway, it would be highly unlikely that he would smell his rear brake burning until he stopped.

I am also not affiliated with anyone here and the only person I have met was you when I let you borrow my intake for a smog.

For me.. On my 900 Supersport I was going down the fast lane at 80 mph. Then 70 mph then 50 mph. At 1st I thought it was a head wind. Then I hit 50 down to 40 and was like wtf is my motor seizing.

So I was able to get over to the right hand shoulder. I got off the bike and looked at the motor.. going to check the oil level. I saw smoke.. Then flame. Then me tossing dirt on the caliper. spit hell I was ready to **** on the damn thing..

After it cooled off for a bit but still way to hot to touch. That brake would not move for anything. It would drag the rear tire. I cut the brake line thinking I could move the pistons back. Didnt have any tools. I took my key and cut the brake line. Got sprayed in the face with brake fluid vapor. That really really sucked....

I then was able to get the pads out. one clip and one pin holding them. After that is was a very slow ride off the freeway into san ramon.

Now this had been like this for about a week. The student failed to set the master rear brake free play on the master cylinder,
So about 50 miles each way to work. 100 miles a day for atleast 6 days. 600 miles before failure. My bike never locked up till it cooled off. I know the STi has more torque and more power then my ducati. So he could have been driving that for a month or two. Your not going to get a failure right away. You could make a bunch of short trips and never get enough heat. Remeber the job of the brake system is to bleed off heat.

I'm not defending anyone I'm talking about what I know. I do think its allot easier to believe that a dealer flat rate tech screwed up. Not the 1st time. Then james bond picking his car out of millions for say covert ops.

Someone call mythbusters.

oh and I dont know the car party involved, I have bought parts from stevens creek and have test drove a few cars from them. Almost bought a car from them too.


oh and I never smelled the rear brake. Untill I vaporized my nose.... lol I think I can still smell that too..

You would smell your brake burning, the same way you smell your clutch burning. Not to mention you should notice a significant lack of braking power after such an event so I find it hard to believe he drove along for a while without noticing either 1) the smell of the burning brake or 2) the severe drop off in braking power.
