Question about torque

Discussion in 'General Motoring' started by Osgood Z'beard, Mar 7, 2006.

  1. Hi:

    I just replaced the front pads and rotars on my Saturn '98 SL, with a
    great deal of assistance from folks on this list. I just had a question
    about the bolts. On each side there were two pairs, one 14mm and one
    18mm. The 18mm bolts seemed to have some old locktite on the threads,
    but pursuant to some recommendations from this list I replaced the
    locktite (after cleaning with brake cleaner) with some nevr sieze
    material, and torqued them to 80 ft/lbs. The 14mm bolts were torqued to
    40 ft/lbs, but I didn't do anything to the threads. I didn't clean
    them, but tried to keep off any dust or grit, and just put them back in
    the way they were. We couldn't find any torque specs, so just figured
    that was a good first approximation. We're sure we haven't over-torqued
    anything, but have we undertorqued? Anyone know the specs for the front
    disk bolt assembly? Is nevr sieze OK instead of Locktite? (I know they
    have different functions, but figured the nevr sieze would allow more
    efficient tightening making the locktite unnecessary.

  3. Actually, take them back out and put LOCTITE back on them. There is a TSB
    out about bolts wiggling themselves out and calipers possibly falling off
    the knuckle. And that was at their torque setting.... It was VERY RARE,
    but did happen. The loctite holds the bolts in tightly a lot better. I
    HIGHLY recommend putting it back on there, the neverseize may actually
    cause bad news quicker..... Hope I could help you.
