Brake Tork specs front rotors to hub
« on: November 05, 2016, 00:34:51 »
I need to find the torque specs for the socket bolts for securing the rotors (discs) to the front axle hubs. I've got the spe  from the manual but it doesn't seem right. i converted 11.5 MBK to foot lbs and got approx 8.5. That seems awfully light. they are big bolts approx 7/16. They look like they should be about 60 foot lbs. They are same size as the wheel bolts and they got to be 60 or 70 lbs. The manual is a pain.. Why didn't they just put all the tork specs in one section and give us some SAE standard specs. They did export an awful lot of these cars to North America. Frustrating to have to convert all the time. Thanks in advance.

I think I use about 85 ft. lbs  which is the same for wheel screws and caliper mounting screws.

Thanks Dan, figured as much. I got the wheel bolt specs written somewhere but couldn't find them.
