Hi all-

Have a 99 altima (sorry, but the nissan group wasn't any help...seems like a
universal problem), about 6 months ago I replaced my front rotors and pads
(raybestos, chinese made), and for some reason, since day 1, when I applied
the brakes I heard this grinding (Grrrrrrrrrr) sound come from the front
passenger brake, I kept on driving...after 6 months of putting up with it my
pad wear sensor started going off (the passenger front one), when I replaced
the pads this time the passenger front ones were worn to the bone where as
the driver side still had some meat left on em. Again, 2 days after I
installed the new pads, the same grinding noise comes from the passenger
side (it didn't when the pads were brand new)...allbeit, its less than
before (no I hear it right before i coem to a dead stop, not from the
begining of the braking as it did with the pads before.

Can someone tell me whats causing this? Id say it was warped rotor, but it
was doing that on a brand new rotor as well, plus i dont feel any pulsation.
Also, when the mechanic replaced my pads last week, he showed me how there
was a lateral movement (play) of the front passenger side wheel, he said the
inner tie rod has to be replaced, is that the cause of the grinding noise?

any help would be appreciated, the car has 60k miles on it...

Unlikely that its a warped rotor from your symptoms. You may or may not
need a tie rod end, but that would not account for the grinding noise and
premature wear either.

If it ate the pads faster on that wheel, the most likely cause is a
sticking/stick caliper. Take the caliper off on that side and see if the
caliper pins move in and out freely or are stuck.

I agree with the other poster, it sounds like you may have a brake caliper
problem causing the brakes to drag on the right side. I also agree that
it's unlikely that a loose inner tie rod could cause the problems your
experiencing. However, you should get that taken care of as soon as
possible as you don't want to loose steering control of your car while your
going down the road.

The following information is from one of my prior posts discussing brake
caliper diagnostics. Rather than rewrite it, I'll just post it as quoted.

While I'm not familiar with the brakes on a '99 Altima, the above
information is fairly basic and should be applicable.

its either the caliper or you have an abs braking system problem.
