There is no shortage of experts when it comes to measuring and determining proper
bolt torque, but there are many considerations here as well.

Bolt torque measures the tensile load on the bolt. It is important to recognize that not
all bolt torque situations require the bolt to be brought to it’s max torque, In fact in some
situations, larger bolts are used to increase shear strength as opposed to tensile strength.

I’ve included a torque chart I commonly use, but keep in mind not every bolt on a car
should be brought to maximum torque. For example, items like gas tank straps just need
to be tight, as over-tightening them could result in damage to the tank or straps.

All brake kits I have installed included the manufactures bolt torque specs. I would
guess that’s a liability issue the manufacture just does not want to deal with. Driveshaft
U-bolts do have torque specs, and here are some common driveshaft component torque
specs as listed by Dana Spicer Corporation
