Anyone out there with the service manuals for the 2001 L300, or anyone else for that matter, what is the thickness spec for the front brake rotors on the 2001 L300 (I am looking to find out the initial thickness, and the minimum thickness at which it's safe to re-use (or turn down to)
Thanks!
Nominal new thickness 0.98 in, minimum thickness after refinish 0.90 in, discard thickness 0.87 in.
Thanks!!!
As an aside, when I first put brakes on my 95 SC2, I couldn't find a shop to turn the rotors for me, even though I had the specs in my hand and the micrometer showed they were within spec. Everywhere but one place said they were too thin. So you might have trouble finding someone to turn them. That was at 125k, I just did the breaks again at 200k and I put new rotors on it this time. The rotors were $20 a piece. Not sure what rotors will cost for your L series but if they're cheap you may find there isn't much of a price difference between getting the old ones turned and just buying new ones.
I've also been pampered in the past with cars that don't have expensive rotors - however, the ones for the wife's L series are $90 a crack (even the ones down at AutoZone are $88 each). I ended up just having the dealership do the brakes (how sad is that!) - no time with the holidays and everything - anyway, Saturn actually turned the rotors - overall, the rotors were fine - they had a little bit of a lip on the outside edge, but other than that were smooth and not out of round - looks like they just cleaned up the surface a little bit, and evened everything out. Anyway - haven't had a chance to put a mic on them to see how thick they machined them down to yet. In any event, Saturn includes resurfacing (if needed) in their "brake job" price - so it's all good!
I had the opposite problem with my wife's SL1: Rotors were replaced at about 60K but were apparently bad from the factory. They quickly started pulsing, so returned to the shop and they turned them. About 15-20K later they were pulsing again. Different shop, insisted they were still within spec, so they turned them again. Then about 15-20K after that again the same thing. Finally, about
15-20K after that a shop I've had good luck with turned them and it "took" -- they've not been pulsing since. I'm fairly confident they won't stand turning again, though.Make sure when you put the wheels on, you use a torque wrench and torque the nuts correctly.
Uneven torque will cause rotor warpage and pulsing of the brakes.
Spec is, I believe, 103 ft-lbs > >>Anyone out there with the service manuals for the 2001 L300, or anyone else
