I think for the BTW251Z though i would need an adapter to for in a screw bit.
BHP454Z is not really suitable. It is a hammer drill for drilling masonry......
BTP140Z is cheaper and more straightforward. However, for car use, the BTW251Z is great for everything else since it has a 1/2" square drive. It is very expensive though, I expect it to cost AU$600.
Personally, a $90 Ozito or some cheapo brand will work since this will not be for constant high stress use.
At the rate that I am torquing it, it is above what the service manual recommends. And yes, I do it in the exact same way as in that photo, with a spanner and ratchet.
However, you still can't get a torque wrench into the area where the caliper bracket bolts are. That is behind the rotor and the torque wrench ends up having to point upwards into the wheel well. Fine if you have a 4x4, but not enough clearance if you have a passenger car.
The torque wrench shouldnt be up in the well.Use a shorthandle 3/8 from below in the same position as above pic
One point to add he is holding the tools in an awkward manner.Far better to position yourself towards the front with right hand pulling toward your body
The mechanic I took my car to was able to use a torque wrench when he did the caliper bracket bolts (NOT the ones in the picture), but this was in an Odyssey.
