You don't really need a torque wrench if your just doing brakes. The only bolts that you need to be careful about are the caliper bracket bolts and they just need to be tight. Torque wrenches may seem like a luxury you don't need, but they are actually used for a very specific, very important reason. The most common and prevalent use of a torque wrench is for changing rims. Torque wrenches allow you to tighten lug nuts without damaging the rim. The front brake caliper bracket's mounting bolts need to be torqued to 80 lb ft. The flange bolts that secure the caliper to its slide pins are 17 lb ft. A 1/2" drive torque wrench will have right range for doing the lug nuts. a 3/8" will probably not go high enough; and a 3/4" or 1" drive will not be accurate as such a "low value" for those sizes. Torque wrenches need to be operated in the middle of their range to be at all accurate. Your caliper shouldnt be loose at all. When your pads wear the moving part of the caliper slides in to keep all that tight and the piston stays out and keeps the back pad close to the rotor. You need to look at the the caliper bolts on the back and also look at the cariage bolts.

If you tend towards stainless/steel bolts and less expensive components, you can forgo the torque wrench and just ensure you are working to even torque. Too tight on a square taper crankset (specifically the fixing bolt) can cause deformation of the taper fit and eventual loosening of the crank.

Here are four common sizes of torque wrench: 1/4" – Good for smaller bolts and nuts that need only 50-250 feet to pounds. 3/8"– Best for most automobile related requirements between 15-75 feet to pounds. 1/2"– Suitable for bigger bolts and nuts that need 30 - 250 feet to pounds.

So long as users operate with caution and do not exceed the maximum torque, most torque wrenches can be used for undoing. However, if the bolt will not free within the maximum torque of the wrench, another tool should be used instead. If in any doubt, use another tool for loosening bolts.

Yep, it works just like you thing(ft-lbs*12 = in-lbs). And yea, about 1/8 to 1/4 of a turn after finger tight is all that's needed for 7 ft-lbs. Just a slight bit tighter than finger tight.

Tight is good, but over tighten is NOT. Over tighten can stretch the stud and cause failure around the rotor. Every car has a lug nut torque specification from the manufacturer. The proper way to tighten the wheel is to use a torque wrench to torque every lug nut to its recommended torque when the car is on the floor.

Torque is used to create tension. Bolts are used to affix two components so that they can resist tensile (pulling apart) and shearing (sliding apart) forces. After the nut has been turned onto the bolt, additional torque causes the nut to turn and stretch the bolt.

After a lot of research, we can say that Tekton 24335 1/2 inch drive click torque wrench is the best one out there in the market. It is the reliable torque wrench for tightening lug nut of the wheel for the most of car brands/models, its torque range is 10-150 ft-lb.

Tapered-seat spark plugs should be installed by hand until finger-tight. Then use an additional 1/16th turn applied with a spark plug wrench to ensure the spark plug has been tightened to the manufacturer's recommendation for a 14mm thread.

Install the wheel lugs by hand. Most manufacturers do not recommend using any lubricant or anti seize compound on the lugs. Push the wheel home on the hub and using your socket wrench, tighten the wheel nuts just enough to hold the wheel snugly.

And when you look at that, and realize that the average torque required on a lug nut, to hold the wheel on, is 80 to 90 ft-lbs, well you can imagine how over-tightened some of these lug nuts are. Now that's a problem because it almost guarantees warped brake rotors.

Realistically, the answer is no. A quick glance at a lug nut torque chart shows that most lug nuts should be torqued between 80 and 100 ft-lbs. Some require less torque, others more. But for the purpose of this discussion, let's say that a lug nut must be torqued to 100 ft-lbs.

Do not use the impact to tighten the lug nuts, though. It is very easy to over torque them. Use a ratchet and finish up with a torque wrench for accuracy.

Lug nuts must be torqued to the manufacturer's recommended values, and they must be re-torqued to those values after driving approximately 50 to 100 miles on your new tires after the tire service. Both under and over tightening can be dangerous.

Re-torquing the wheels involves tightening the lug nuts to help ensure they're not too tight or too loose. Too tight, and the nuts can damage bolt threads, break fasteners or warp new rotors. Too loose, and your wheel could fall off when you're driving.
