Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

On a reassuring note I have seen some discs on a GT3 that had been tracked where the cracks were significant and an inch long, the discs looked totally shattered and were still running though were in for replacement and I should think so too!

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I first posted about this maybe five years ago when I first bought the car. I had a night at Bruntingthorpe with an ARD instructor to introduce me to 911 handling (and very worthwhile it was too!) however he wasn't particularly sympathetic in giving consideration to my brakes. The two centre rows of drilled holes on the front discs formed spidery little cracks caused by heat build up. Some one kindly advised me on the forum at the time that the serviceable tolerance is 7mm end to end of the crack total length. Fortunately my cracks were not this big. I asked the question at the time whether the cracks disappear with wear and was told not (I wasn't expecting the brake disc fairy to appear, my thinking was the cracks may be surface only and not consistently cracked through the disc). Well some 15000 miles later many of the cracks have disappeared with just a few traces of visible but almost vanished lines where small cracks once existed. Has anyone else experienced this? On a reassuring note I have seen some discs on a GT3 that had been tracked where the cracks were significant and an inch long, the discs looked totally shattered and were still running though were in for replacement and I should think so too! Any similar experiences out there?
