View Full Version : OMG, the importance of a proper torque wrench.

I was doing the brakes with a buddy today.

We were on the first wheel.

He was using some POS torque wrench from PEPBoys.

He was torquing the allen key bolt onto the Brake Carrier, the bolt that holds the caliper on the big piece. All of the sudden, we hear : SNAP. We both thought, OMG, that's a bolt snapping. It did turn out that the bolt snapped right in half, stuck in the brake carrier peice. Luckily, we we able to get the brake carrier off, replaced it and got new bolts in the kit.

This same torque wrench was responsible for him snapping his oil drain plug as well =(.

Very expensive piece, and a very expensive lesson on proper tools required in precision tools.

We will both get the Craftsman 3/8inch digital torque wrench on our next DIY project.


But, the Hawk HPS pads and new rotors are great.

In particular, you need to unwind them back to zero (or the lowest setting if they don't go all the way to zero) before putting them away. Otherwise, they will wander upwards (you will be applying more force than you think you have set on the dial). The manuals often also suggest annual calibration, but the cost of the calibration plus shipping is often more than the tool costs to replace.

Craftsman is just one notch better than PepBoys.
I have one, and although it hasn't failed yet, the ring lock (something that's supposed to keep the selected setting locked in) has broken.
I just don't use it enough to justify a Snap-On, or I would.

Annual calibration? For a tool that isn't ANSI when new?
:dunno:

For real sticker shock, go price a quality certified torque wrench.
:yikes:

I've got one of these from SK Tools (http://www.skhandtool.com/index.cfm?tok=1&) :

They list for ~$130 but you can find them for ~$80 in some online stores (that's where I got it).
IMO unless you put engines together on regular basis you don't need a better one, sure beats a Craftsman.

I also bought an SK... I think I paid ~$70 on shipping -- do a search online for the best price...

I got mine from The Tool Warehouse. (http://thetoolwarehouse.net/shop/MAN65.html)

Ditto here. An SK 25-250 inch-lb 3/8 inch drive for small jobs (the oil filter cap, approx $72) and an SK 20-150 ft-lb 1/2 drive for bigger jobs (lug bolts, approx $78). KD is also a good choice, and a bit less expensive than the SK.

Same thing happened to mine. That plastic ring cracked off. A couple metal clips sprung out. And it leaked some oil. I still use that for torquing my lug nuts. I keep it all the way up to 75 becuase it's now not easy to dial down.

For mroe precise things like the oil filter cap, I borrow a Snap On torque wrench from work. :D

Any idea how much one of those Snap-On torque wrenches costs? :yikes:
