Caliper service

I don't use a torque wrench ever, but as it happens both the snapped ones I've had snapped with very little pressure when being undone.

Some of the tyre guys in Slacks Creek use airtools undoing and refitting those bolts I nearly had a conniption the first time I saw it done

I rarely use torque wrench on cars/4wd, excepting where you need to. Engine parts, flywheels etc. On bikes i have 3 that are always used. Never Seize and Torque Wrench, go together quite well for the tiny shit bolts on bikes.

I always use a torque wrench when rebuilding calipers as need to make sure they are at 25Nm - I dread to think of anyone having an issue with something I have done and it was down to a loose bolt

Other than that its all UGGA DUGGA - I reckon 7 Ugga Duggas is sufficient for most applications

I used my torque wrench to do them up , 3 of them went to 25nm, the fourth just sheared off so I guess it must have been fatigued. It's just as well it happened at home, anyway 4 new titanium bolts are on their way

I will use a torque wrench most times, especially on important stuff like brakes and suspension, and on plastic bits like intake manifolds on modern diesels.

Recently changed out air struts on my land rover, after the originals had done over 200,000km.  The lower mount bolts have to go to 300Nm.  Undoing the old ones, the fronts were nowhere near that, and this is after "factory trained" mechanics had replaced the lower control arms the year before, meaning that they would have had to remove the strut to do so.

As you know a caliper bolt snapped , well today I went to remove the rest of it an d luckily for me there was enough of the bolt protruding from the other side that I was able to get some pliers on it, wind it back in to get the pliers on the snapped end and it came out easy as pie, no damage to the thread on the caliper as well so all good there, happy days

4 new titanium hex bolts arrived today hurrah!!

[GSXKING]

You've probably saved about 5 grams of weight as a bonus 

[Hooli]

Blowing your nose will save as much weight as the cross drilled heads.

[Tally]

 :rofl2:Being a fat bastard I need all the weight saving I can get 

[GSXKING]

If you take a good dump before you go riding you'd save more weight than the new bolts 

[Hooli]

But the bolts are unsprung weight so more important 

[Tally]

Help and advice pls. Can anybody tell me what the diameters of the front calipers pistons are as I've been sent some and they look way too small . They are 8x27mm & 4x24mm, I've looked at the pics of my caliper re-furb a while back and the pistons look much bigger. Thanks Tally
