I just replaced the front rotors and pads on my 2007 S600. I ordered Brembo Rotors drilled and vented from Rock Auto and Hawk Ceramic Yellow Pads from Hawk Pads for lower dust. Bedded in the new pads over the next 300 miles gently. Now my baby stops smooth as silk.

Good job. Now do the rears.

I changed pads to Hawk ceramic pads in the rear about 30K miles ago. Did not change the rotors at that time. The rear pads still look pretty meaty; so I will plan to change them in the Spring. Will use new Brembo rotors again. They were marginally more expensive than others, but I think there is good value.

BOTUS

thought so - BRAKE DISK, VENTED

rotor = an assembly of rotating blades that supplies lift or stability

vettebk

I stand corrected. I changed vented front Disks and Pads.

I mean, dealers call them rotors, too.

BOTUS

doesn't mean they are correct.... it means the common parlance has got you there - but there's always an opportunity to get it right

tree branches sway in the wind - but when I drive round a corner - physics makes the car roll, so the manufacturer fits an anti-roll bar

I think it might be an American thing. They are correctly called Vented Disc Brake Rotors (note spelling)
https://en.wikipedia.org/wiki/Disc_brake
and since high school 60 years ago we simply and lazily called them Rotors or Disks.

But I yield to Botus who is one of the more discerning members here. I will call them properly going forward.

Most "Car guys" can not define a how a motor is deferent from an engine.

Rotor is not incorrect, it's just perhaps inadequately descriptive. Except that, near zero people on this side of the pond would be confused by the term "rotor" in the context of vehicle braking systems.

Merriam Webster says:
This is akin to arguing about boots, bonnets and windscreens.

BOTUS

boot and bonnet vs trunk and hood, have some logic in either "language" ...

a wooden storage box with leather straps is indeed a trunk - and in the old days these where mounted externally at the back of the car even in Britain. But when it became an integral part of the car and enclosed thus water tight, we moved to the later name (not sure how it got that name, but I guess the first people with cars used to go shooting and likely had their man put their muddy boots in the back)

the bonnet vs hood bit is more intriguing, I guess the bonnet was fitted to hide the ugly, oily, smelly engine to make things prettier - hence the female name of a bonnet. Maybe using the masculine name of a hood, says something about the preferences of USA men?

when we get to a rotor for a brake component its just wrong, and disc is better (and thanks vettebk - only yesterday did I get the point u made about spelling when I muddled Disk and the correct word Disc in my earlier post... - just checking Disk is the British and older spelling but seems we moved to disc for flat round objects and then used Disk again when computing rocked up ). Again checking, rotor is usually part of an electrical device, aka part of a generator or the rotor arm in an ignition distributor

like sway vs roll - cars don't sway, so we have anti-roll bars

fender is a make of guitar and a cheap easy to replace "bumper" is used to take the damage of bad parking / small accidents at the front and back of the car where idiots bump into you

car's derived from a horse drawn carriage and many didn't have mudguards. As we extended things to find room up front for an engine and went quickly we needed the mudguards - these in many early designs swoop back and incorporate running boards... with no decent thinking, I guess many felt the swooping design were a bit like an angel's wings. Hence Britain used the name wing. And now I'm muddled between what is a USA fender, the wing or the bumper ?

if we really want to wonder what is going on - whilst bigotry got us there and common usage brings a limited excuse for using the wrong word - what is it with other countries muddling up the comma thousandths separator and the full stop for decimal places ?


when I asked - what is the name of the idiot that created american spelling - it came up with this https://en.wikipedia.org/wiki/Noah_Webster

.

vettebk

I think a car's wing in America is called a quarter panel. I have no idea why.

We also call idiots in Congress the Honorable Gentleman from (Pick a State); and I have no idea why. They are neither Honorable nor Gentlemen. Noah Webster died in 1843. So he wouldn't know a car from a buggy nor a knucklehead from a statesman. Such are the current times.

JohnLane

Purchase the right car and it will be equipped with a clever system using hydraulic pressure applied such that body roll is eliminated. Sway bars ‘lift’ the inside tires. We do better with ABC and MBC.

BOTUS

ah yes, thanks - I guess because you have four, one over each wheel ?

re webster, reading that page he hated Europe, which (would mostly) explain why he removed the latin, greek and french spellings that let us understand what a word meant... whilst language evolves, some bits help. Those that got an education can work it out from the spelling (not me - I was the era where the UK gave up on doing things correctly). Its odd he didn't correct physics to fizics ?

vettebk

Once again, totally correct BOTUS. Webster was anti-British. Here is an except from his bio:

Born in West Hartford, Connecticut in 1758, Noah Webster came of age during the American Revolution and was a strong advocate of the Constitutional Convention. He believed fervently in the developing cultural independence of the United States, a chief part of which was to be a distinctive American language with its own idiom, pronunciation, and style.

Such anti-British sentiment no longer exists, thank heavens; and the "Special Relationship" is the norm today. Most Americans are true Anglophiles, me included.
