W126 Front Brakes
Time to replace the front brakes, pads and rotors on my 380 SE. To do the job, I will likely need new front wheel bearings as I understand that the bearings are sunk into the rotors. I guess I can't reuse them
Any special tricks or tools required? Cheers, John |

You can replace the pads and rotors without touching the bearings. I'm not sure what you mean by "sunk into the rotors".

w 126 brakes
Is the 400 SE a w126 car? Maybe I am not up on my nomenclature, but I will take another look at the diagrams. I just thought the wheel bearing races were stuck into the back of the rotors, and were sold seperately with the wheel bearing kit. I may be wrong, I have not yet taken it apart.

Just did mine a couple months ago. Wasn't too bad a job to do.
The bearings are pressed into the hub, which the rotor is bolted to. Take off the rotor assembly, being careful not to damage the rear seal. Then hold the assy in a sturdy vise and take off the bolts and it comes apart. Seems to me the bolts were allen head style, so you'll need a metric allen wrench. I think they were 8 or 10 mm, but can't remember for sure now. Anyhow, as long as you keep things clean, ect, you shouldn't need to touch the bearings as long as they are in good shape and well greased. Check the rear seal to make sure it's not worn and leaking. Check your calipers for any leaking of fluid. Check the brake lines for kinks or cracks. Hardest part I had was getting the caliper pistons pushed back in far enough to get the caliper back on over the new rotors with new pads. Was almost as if something was to thick, either the rotors or the pads. But finally got 'em back on. Once they wore in, they work great! Good luck!

funny you mention this piston issue rick...I just did the pads on mine and I actually ended up HAVING to get out the electric hand sander and shave off about 1/16" pad material just to get that #$%#$ in there.
Glad to hear it isn't just me :p

w126 brakes
Thanks to all for the suggestions. The CD rom manual suggests that the bolts which hold the rotor on the hub should be replaced as they are self tapping. Did you reuse them? Likewise there are some caliper bolts which they suggest replacing. We shall see.
