brake question

i took my car in for an alignment today, and the guy said my brakes need to be done in a few thousand miles. he told me on benzes when you change the brake pads you have to change the rotors also....i have never heard of such a thing unless they can not be turned because of the thickness. is there any truth to this? and if so, what rotors should i invest in, or should i spend the money for a big brake kit?

cheers

Aaron

after doing a search i found my answer about the rotors being changed at the same time, but if i do need to change my rotors, is there a brand out there better than another, or do i just go with stock....

are there OE fit rotors that are either cross drilled or slotted that i would be able to pick up?

cheers

Aaron

The reason that the rotors should not be turned on Mercedes is because, if they are thick enough, you should just slap a new set of pads on there. Mercedes rotors are soft so that if you use a set of pads on them and then turn them, you will beyond min thickness.

On my car, I change the rotors every other set of pads, and without turning them they barely last 2 sets of pads before being worn beyond minimum thickness. But then again, a good OEM quality rotor runs $40-$45 each for the front, so it is not a very large cost for new rotors.

A word on pads- not sure if it's the same for the later E-class, but I found Pagid pads to be poor, with a lot of grind/squeal once warmed up. Switched to Textar- better feel and no squeal

where are you buying rotors for $40-$45 the lowest i have seen is in the $60 range..

I purchased the Brembo rotors for my ML320 and was impressed with the quality of the machining. They come with a super fine cross-hatch finish on the braking surface to aid bedding of the pads.

Balo rotors are fine, but you need to cross-hatch them with coase sandpaper before installing them.

Unless you are racing (on a track), crossdrilled or slotted rotors will reduce, not increase, your braking power, and the crossdrilled ones will crack sooner or later. Stick with solid ones -- you may not look as cool as the next guy, but you have MUCH better brakes! Someday you might want them in a BIG hurry -- like the high school kid who had a loaded tri-axle pull out in front of her on the highway on Tuesday.

Yes, sorry, I was referring to rotors for my W202. Yes, the W210 rotors are a little bit more expensive due to their larger size.

And you DON"T want cross-drilled rotors on a vehicle designed for off road use! All sorts of debris can get imbedded in the holes!

i use the car for a daily driver, it is all stock other than the wheels, i just figured if the cross drilled and slotted were the same amount of money, i would get them for looks.

it looks like i will go with a stock set up. i read on another post it would be good to check out the wheel bearings if you have the rotors off.

what is involved with checking the wheel bearings? is this something i can do at home? do i need special tools?

Actually, the comment about cross-drilled rotors was directed to owners of "off-road" vehicles...like the ML and the G.

There are REAL reasons for cross-drilled rotors in racing applications, but for street use, it's mostly for looks and bragging rights!
