Hello,

I cannot find any information on the tightening specs for the front caliper bolts.

Does anyone have access to WIS that can see this info? FCP website states 80nm + 45 degree turn. It seems low.
If there is a service guide for the entire brake rotor replacement procedure, that would be welcomed.


Thanks!

did you ever find?

so interesting question here. part # 0199907901

i replaced them when i just did my front brakes again

you can see here they quote 80nm + 45° through FCP Euro

i asked my dealer to confirm with a tech through the WIS what it says and he asked for my VIN and then told me 150nm + 45°

i asked the guy again for a 2020 E53 and he said yep 150 + 45. that sounds like it's absurdly high and clearly wrong to me. i torqued them to 80nm + 45 which worked out to around 100ft-lbs if my torque wrench was correct. they felt quite snug and secure. surely 150nm (approx 110ft-lbs) would be crazy PLUS 45 degrees. does anybody have access to the WIS who can confirm for me

The correct torque is two uga dugga's

I deleted an unfunny joke...

I found this online. I make no guarantees as to accuracy but seems to match what dealer tech said. I'm kind of shocked it's that high. I guess I should tighten it more
