Name/size these Brembo carrier bolts?

[Dave]

Was disassembling a car to do rod bearings and the Brembo kit on it (380mm, 4-piston, so I think GT, but honestly I have no idea) was WAY overtorqued to the caliper bracket. All four bolts took a breaker bar the entire time to remove... it was quite a workout.

Obviously they're stretched and garbage. I'd prefer to get the exact same bolt, hex head included, rather than just trying to match size and threading. But I have no idea where I'd find them. Anyone have any ideas on size and a reseller?

Looks like your standard Socket Head Cap Screw. Any local fastener store like Fastenal should have it. If all else fails, the tried-and-true McMaster-Carr will definitely have one that is an exact match

Looking at the end of the thread on your bolt, are you sure the thread in your carrier isn’t stripped???

I have the exact same brakes as you, I will measure my spare bolts this afternoon and will reply back. I think they are M12x1.5x70mm but let me double check to make sure.

And if you can't find anything locally, here's another option: https://www.belmetric.com/allen-socket-heads-c-6_339/

Though I kind of wonder if they just resell McMaster-Carr LOL. Also wondering the same as Gt4 with the threads in the bracket.

No, and that is a HUGE concern because in addition to being stupidly overtightened, they were also installed incorrectly and backwards.

So yes, I know what you're thinking... are the calipers themselves F-ed... and that would be my next big fear.

With my 20 years of luck with these cars, I expect that to be the case. But at least in this case it's not the end of the world, I didn't pay for these.

How can they be mounted backward??? Seems impossible to me due to the offset in them, you wouldn’t be able to fit calipers on rotors.

I was correct, the bolt are M12x1.5x70mm. I have 4 brand new bolts if you want
