96 maxima gle...in trying to replace my rotors, I seem to have gotten
stuck at the point where I have to remove the two torque member bolts
(each side).

For some reason my 17mm socket wont even fit on any of these 4 bolts!
I will try to pick up another 17mm to check it, but wondered if this
could possibly be an 18mm bolt?

They also seem to have been put on to some ungodly torque and refuse
to budge (tenderly using adjustable wrenches).

Just wondered if anyone else had similar problems.

Thanks

Lake

I believe they are 18MM. Why is that unusual? It's a common size despite
being left out of some socket sets.

The torque member bolts on my 95 are 17mm (it's STILL on jackstands, so I
just checked). I didn't change mine out, so I don't know how big a gorilla
it takes to get the job done.

I mentioned the 17mm didn't fit because I have seen 17mm mentioned as
the size it is. Anyway, I think its 18mm (which I didn't have), but in
messing around with it, I found that a 3/4" fit snug as a bug and so
far I have gotten one side off and replaced the rotor and pads. The
other side is still tight/frozen...If it goes as the first side did it
will probaby take alot of WD-40 (thats all I have) and a nice solid
pipe.

Thanks

ps Maybe I was wrong in assuming the 95's and the 96's were the
same in this regard..

Galvonics takes effect since the Japanese use recycled metal and between
the bolts and castings there are different galvonic values and that
causes them to stick. I suggest getting a long cheater bar to take them
off. Just make sure you tighten them up to the factory specs. I think
for that bolt it was 100 pound feet of torque.

The specs on the dealer schematic at the Infiniti parts counter, as I
recall, was something like 64 pound ft.

100 just doesn't sound right & I'd recheck that figure.

Yup, 100 ft lbs is WAY too high. The correct specs are 53-72 ft lbs
for the front brackets, 28-38 for the rear. 64 would be good.

3/4" and 19mm are real close. I've never seen an 18mm bolt used on a
nissan or any other japanese car, the americans use that size for some
unknown reason. Maybe because this size is never in a set of sockets?

I think these are 18 mm bolts from my last experience.

Well...the rotors and pads are installed and seem to be working fine.
That was the first brake work job for me. Thank goodness for
www.motorvate.ca and the info there.

I still don't know what size those bolts are..and there were 2 on each
side. I seemed to do fine with the 3/4" socket I had, that and 1.5
days of WD-40 and a nice 15" stretch of galvanized pipe I ended up
purchasing for about a buck fifty.
