Hind sight is 20/20! I put new front brake pads on my 99 suburban 1500 4x4
about 6K miles ago. I had the rotors turned and the guy that tuned them
said the one was slightly under spec. I let it go and sure enough, they are
warped pretty bad now. Not sure what it is with the 99 burbans, they seem
like it takes a lot of braking to stop those tanks! I picked up some new
rotors and getting ready to replace them. I got lots of meat on these
almost new ray bestos pads. Should I replace the pads to or will it be OK
to use them again?
There will be contradiction to this I'm sure...Have the rotors turned
BEFORE you install them. I have only come across about 20% of new rotors
that didn't have at LEAST a slight bit of runout. Cheap insurance for longer
life and good breaking. As for the pads, make sure there is no glazing on
em(med. tooth file or med. grit sandpaper) and reuse em!
That might be more true of the more high-end brands, but I HAVE had more
than not needing to be turned of even the best replacement rotors AND drums!
I recommend it anyway, it is still cheap insurance! Besides, its worth the
money having it done BEFORE the labor is spent putting them on to only have
to take them off again! No since in taking a chance and doing a job twice
when one small precaution can be taken!
You should be able to use them again. I'm surprised that the
fellow turning your rotors let that one rotor back onto your
vehicle when it was under spec. That's not really kosher.
You also need to make sure that the hub surface that the
new rotor mounts to is perfectly clean and smooth. You
cannot leave any rust on that surface as your rotor will
then not run true with respect to the brake pads. Within
a few thousand miles....the rotor will be warped again if
you don't address this item.
These vehicles were particularly hard on front brakes.
Poor design as far as I can see.
