Need some help here please just been replacing my rear disks and pads on the e55, fairly straightforward, just a pig to get off the handbrake shoes. my question is,how do you guys tighten the caliperbolts to 180 nm when the car is on a jack? my torque wrench is massive and just cant get it to fit or get enough leverage to get anywhere near that, smaller torque wrenchs dont go anywhere near 180nm. will be doing the front tommorrow which will probably be easier because of the lack of handbrake and the fact i can turn the wheel before i start! any advice appreciated!
