Bought a new set of front rotors (Canada Tire) for my 2000 300m. Had
2 choices - standard quality and "premium" quality. Difference seems that one is made in China, the other in the US of A. Since the standard quality ($60 each) was out of stock, I bought the premiums ($75 each, or $62 USD).The box (white) was pretty much devoid of any branding, other than a Monroe decal ( - used under license from Tenneco Automotive). There were a bunch of numbers on the box.
Internet searches for BD125638 comes back as a Wagner PN from several sources. Bar Code 008536425717 comes back as Cooper Industries, which has a Wagner brake division (previously known as Federal-Mogul ?)
Not sure why these Wagner rotors need to have a Monroe label on them (what's the connection?)
The rotors themselves have the following castings:
Century Made in U.S.A.
637090 MINTHK 24.4 mmMy original rotors were turned Apr 2004 and over the past few months I was getting too much pulsing during braking. They were down to 0.973 inches (and weighed 14.5 lbs each). The new ones are 1.027 inches (26.1 mm) and weigh 17.7 lbs each. Some say the thickness of the originals (when new) are supposed to be 1.019 inches (but I think they were at least 1.020 and probably closer to 1.025.
I estimate that rotor wear is something like 0.4 to 0.6 thou per 1000 miles.
In reading some of the brake stuff that has come up doing these searches, it occured to me that I should have take a wire wheel to the hub and made sure it was perfectly clean before mounting the rotors. Oh well, I guess I'll be doing that when the snows go on.
