List, thanks for all the help with questions about my Spitfire vertical link. On my second try with a heli coil I got the caliper bolt to hold with the recommended 65 ft/lbs of torque. The first time
Uhm, so what happens when you jump on the brakes for a panic stop and the force on the threads goes up? The force on the caliper is going to be somewhere around 1/3 to 1/2 the weight of the car. Ran
Most of the force will be shear force on the bolt not pull force on the threads. That was how it was explained to me. Sent from my iPad force on the threads goes up? The force on the caliper is ** tr
Quite true, the threads only get a fraction of the force. How big is a fraction of a half ton? Randall ** triumphs@autox.team.net ** Archive: http://www.team.net/archive
Apparently less than 65 ft/lbs. Sent from my iPad fraction of a half ton? http://autox.team.net/mailman/options/triumphs/levilevi@comcast.net ** triumphs@autox.team.net ** Archive: http://www.team.ne
Ok, I'll buy that. So the force nearly doubles during panic breaking. Is your new joint twice as strong as the old one? Randall ** triumphs@autox.team.net ** Archive: http://www.team.net/archive
I trust that Standard Triumph engineers designed brake systems and specifications to include the possibility of panic braking. We should park them if they didn't. Bud Sent from my iPad your new joint
Well, perhaps I misunderstood. They also did not design critical bolted joints such that missing one or two threads would cause them to fail. You posted "The first time I followed the hell coil inst
The important thing is if the bolt can be tightened to 65 ft/lbs. That's the design spec with or without a heli coil. One way worked one didn't. Unlike some I do like my car to be safe. I'm ok with t
I guess we all have our priorities. Mine would be that the bolt not rip out when I pounce on the brakes. Randall ** triumphs@autox.team.net ** Archive: http://www.team.net/archive
I don t understand why you think that would happen. Is there some information about hell coils not working that you re not referencing? Bud Rolofson Extreme Parts Racing (more than just a haircut) 71
No, Heli-coils are fine. But the joint should not have failed just because you left out the last turn of Heli-coil (as directed). There is likely something else going on. My point is that the maximu

Here's my two cent's worth. The bolt is in shear. The clamping force applied to one brake pad by the piston is balanced out the pad and piston on the other side. TR6's are notorious for having woobly
Unless the bolt is too short for some reason, I don't see how this could be the case. I would expect a Heli-Coil to work fine in any application where it's installed according to directions. The only
