Good catch deanyel. Yes, it is very important to torque them equally in a five pointed star pattern. I have found that MB's are durable enough to just snug them up by feel in a five pointed star pattern, but if you don't trust yourself to feel that they are snugged the same it wouldn't hurt to use a torque wrench. I use a torque wrench on about everything BESIDES a Benz.

Yes, 100ft/lbs with an electronic snap-on.

it's supposed to be 110 ft/lbs babe

Yup, sorry. Typo.
100ft/lbs is for my landcruiser...

A sticking caliper piston can give vibrations, make sure they can move freely.

Rob

Sure, but wouldn't a symptom of a stuck piston pull the car away from the weak side?

Not on the rear.

speed, as far as I know the correct torque value for 124 lug bolts (M12) is 81 ft/lbs. Larger diameter lug bolts (M14) on newer MB automobiles require 100 ft/lbs. (It's possible the W124 500E's and E500's have larger diameter lug bolts that require 100 ft/lbs.)

Old post but just FYI:

Yes the Park Brake engages a shoe pad mechanism. Which pushes outward against the inside the disc or rotor. The regular main brake "pads" squeeze (outside of) the rotor like a vice when applying the brake pedal. :cool:

Typically vibrations are caused by faulty wheel bearing or hubs. More prominent at 45-50 mph speeds. But if you only feel the vibration when braking then possible glazing on pads or lower control arm ball joints. Though if LCA are bad you would also have tracking on uneven roads or car pulling or drifting like if it needs an alignment. I know on E30 BMWs they make a clunking noise when driving over driveways entrances or potholes

YOUR LUG NUTS ARE TOO TIGHT CAUSING THE ROTORS TO BOW, THUS VIBRATE WHEN BRAKES ARE APPLIED!

:D LMAO yea I find it funny when I read comment like this.
Most common is, "rotor warpage". It is near impossible to cause any fluctuation in a rotor. To come even close you'd have to travel at F1 or NASCAR speeds to get them glowing hot, then stop. Leaving the brakes on to let the pads bake into the metal.

Warped rotors are very common in Europe

Getting brakes glowing hot is unfortunately easy, no need for F1 speeds, a mountain and a lot of hairpins will do. Even start and stop traffic downhill or emergency stop on the autobahn can warp your rotors. It is worse there is water on the road.

Some rotors are warped when new, even good brands, I always check them first.

One thing to check before replacing the rotors is the surface of the hub, even a little dirt can get the rotors out of alignment.

-Warped- Brake Disc and Other Myths

Excerpt from link:
"...in more than 40 years of professional racing, including the Shelby/Ford GT 40s – one of the most intense brake development program in history - I have never seen a warped brake disc."

An other place to avoid

Rob

What? The site or GT40s? :D
