What bolt size?

[Mr Squashie]

Turns out I have the strength of 10 men and didn't realise it, and have snapped one of the 17mm bolts that attaches the carrier to the caliper on the rear of my 182. Currently in the process of drilling out the remains but obviously will need a replacement. Any idea what the thread pitch etc is for it?

M12x1.75 possibly

Might have a spare I can measure tonight

 

[Mr Squashie]

I've cracked the f**king caliper trying to get the remains out, so I've had to order a new one. I presume that will come with those bolts 🤞
Thanks anyway

I now remember why I don't usually bother working on my cars 😂

 

[Krarl]

Fucsake Steve you've whacked it too hard with your handbag haven't you! 😂

 

[Mr Squashie]

Well how else are you supposed to remove stuck bolts?!

If it's the complete thing including carrier, it should do yeah.

Just the bare caliper, probably not.

Those bolts only need to be 40nm or so, so not mega tight. The caliper body is only cast aluminium.

I think the previous owner over torqued them, they were unbelievably tight when I was taking them out. Then when I torqued them up it snapped at the exact time the torque wrench clicked at 40Nm

That size bolt ought to take a lot more than 40nm, must have been previously stretched

Yeah, would easily take over 100Nm.

Same diameter as a wheel bolt.

The front caliper to carrier bolts are 40nm (13mm)?
Rear brake caliper bolts are 100nm
Rear Caliper yoke (carrier) mounting bolts 60nm
and loctite if going to factory spec.

Bolt size: M12-1.5 x 26mm. The pitch is metric fine on this M12 (1.5). Bolt type: Hex Head Cap Screw Partially Threaded DIN931 or ISO 8765. But I don't know where the hell I get a new one... Renault discontinued it.
