What's the best way to clean the Loctite off the bolts? I've wondered about the 85 ft/lbs....it seems like too much. Steve said he's been using no Loctite and anti-sieze and as long as you check them before every event he's been fine.NFSBOSS said:I was over at YoPauly's house today helping him install Eibach R1 coilovers and a new MGW Gen 3 shifter. We have both had this caliper issue and he came up with the following suggestions:
1. Remove the OEM thread locker from the original bolts and only use blue loctite. The OEM stuff is really strong and might be the main cause of the threads getting messed up.
2. Torque to 70-75 ft. lbs. The recommended torque is 85 and while that might be fine for removing them every 100,000 miles you probably don't need them that tight.
3. Safety wire the bolts if you're concerned about the above.
4. Take a file to an old bolt, you should be replacing them every few times you remove them, and cut a groove into it and use it to clean up the threads each time you remove the caliper.
NFSBOSS said:Yep I did not use loctite the last couple of times I removed them. You'll need to find your own level of comfort on what you want to do. Mike what have you been torquing the bolts to? It's always a good idea to use anti-seize when bolting steel into aluminum.
I'm thinking 85 is too much. My mechanic thought so too when I first encountered this problem. On the ones I have stripped it seems they let go after 80 somewhere and they seem like they're awfully tight as I'm trying to get to 85. Maybe 75 is the magic number......the rears are recommended at 76.06mach1 said:Torque? What the heck is torque? LOL! Lots of bolts and nuts I use a torque wrench on but caliper bolts, I do not. I use a long pattern wrench and both hands. I get them tight. Probably ends up around 75 ft.lbs. Should I be using a torque wrench? Probably. Not as an excuse, but I have been doing this going on 30+ years now. As far as never seize goes, I do not apply it every time I take the caliper bolts out. I probably use it twice a year.
I wonder if that hammer technique is used in designing computer chips too?ArizonaBOSS said:I use a 15mm ratcheting box-end wrench and whack it a couple times with a 2lb hammer once the bolts are snug. Never had a problem with the bolts backing out.
Same procedure to loosen as well.

steveespo said:I know you didn't use the hammer on wrench technique during the engine build up Drew.
ArizonaBOSS said:You're correct on that one. There is a time and a place for blunt force, and that is not it.
