Hyundai car making strange noise

I checked it, it seems tight.

Forget this group...

 

It's a family car and the rest of the family doesn't agree on doing
this hubcap thing,
for the reasons I've given.

 

sight unseen, sound not heard, it is impossible to diagnose

 

There are a lot of good brake greases available. I'm currently using
a purple colored Permatex product (brush in cap style) that may
actually be relabelled Ceramlub. Its visible properties and
performance seem OK but it's too early to tell at this time. If you
are in NY, then you just have to suffer the consequences of nasty
weather and salt (if used). I would suggest on caliper bores that
aren't corroded, you don't brush them or their pins, but clean and dry
with solvent/swab/whatever. There's no reason to abraid the corrosion
resistant coating if it is still working. On corroded parts you have
to wire brush or replace. The rubber components are usually the
culprit when a pin gets corroded. If you replace them with the
typical aftermarket boot kit you will probably be in for more of the
same as they are often thin, distorted junk compared to OE. They
barely hold up here in mostly decent weather, I can't imagine crappy
boots standing a chance in the N.E.

 

Antiseize isn't a terrible thing to use on sealed slide parts, but it
isn't ideal or recommended for this application. It isn't quite the
lubricant that silicone/ceramic products are and it doesn't seal out,
shed or adhere in moisture as well.

 

Okay, thanks for the Tip, MTD. I'll keep using that brake grease that
I buy in little tubes then. I find one little tube will do two
calipers/anti-squeal shims. I would hate to go to all that trouble
only to find the pin slides *dry* from seepage or some such.

Yep, upstate NY. Never heard of nasty weather here...;-) Salt? OH you
mean "corrosion accelerator"..


I currently use Permatex Ultra silicone. Seem to work OK but I wondered
if anyone had a better lube. Normally I just flush the bores with
solvent and dry them. Pins get cleaned and burnished or replaced if
pitted. If the seals are intact then I clean the grooves and apply a
thin coat of permatex sealer to hold them secure once installed. I see
the same thing with the aftermarket crap.

 

If you don't mind me asking, what do you mean by (or how do you go
about) burnishing the pins?

Thanks.

So you couldn't hear in the recording? Did you turn it up loud enough
and listen for the
chittering at the times I mentioned?

 

Use a fine wire wheel to get any crud off. Then clean the groove real well.
Then the pins get hooked to a mandrel (high tech - cut off bolt that
will thread into them) Then I use what is basically a flat knife steel
to smooth them out. Takes about 30 seconds to do each one. They are
smooth then.

I've been thinking about buying a couple new caliper mounts and seeing
if they can be bushed with a bronze or stainless sleeve.

 

I see. That's going pretty far but I like your methodology and
perseverance

 

I HATE sticking calipers!!!!
