Rear brake job on W140
 

Been lurking and searching here for a while and have convinced myself that I can tackle doing the rear brakes on my 1995 S320.

Changing out the pads seems to be pretty straightforward. I am also considering doing the rotors as well, but haven't found any suggestions on what to do/not do on the 140 when changing out the rotors.

Any help & suggestions appreciated.

This is my daily driver so I'd like to have everything ready and planned out before I start.

Thanks much,

Piece of cake
 

If the W140 is similiar/identical to the W124's its very simple/straightforward. Remove the retaining 2 pins that hold the pads in place. Remove the rear brake sensor if so equipped. Unscrew the brake reservoir cap. Using a C-clamp( or a wide flat screwdriver in a pinch) Gentle and carefully press the pads away from the rotor disc. Be sure to press them completely out as far as they will go. You will need the entire space to put the new pads in. If upon installation, the new pads don't fit, put one of the old pads back in and pry the piston back some more. If you have lip at the outter edge of the disc that's any more than a nickel in width, you may want to consider replacing them. Generously apply WD40 to the center hub area. There are 2 (17 or 19MM)bolts that hold the Caliper to the carrier. Remove the 2 bolts and the caliper will come off. Support it out of the way such that it does not dangle by the brake line. There is a 5 or 7MM allen that hold the rotor disc to the axle carrier. Remove it. Use a brass hammer or a mallet and a block of wood or gentle tap the disc directly IF YOU ARE SURE THAT YOU ARTE GOING TO DISCARD THEM until the rust is broke and the disc falls free.

Also check out this pictorial. Its for the E class, but should be of some help.

Happy motoring!

Great! Thanks!

I'd seen the page on the W124, and it looked a lot like my 140. I'm glad to hear that the job on mine is pretty well the same as a W124.

You just saved me about $CDN350!

Glad to be of assistance
 

:cool:

Just wondering, are the W140 front rotors part of the hub or can you remove them without messing with the bearings?

Absolutely
 

Same procedure as above:cool:
