| Photo DIY- W463 (G55) Front Brake Pad Change
Well, 80,058 miles, and the Original Brake Pads Finally Wore Out, and Wear Sensors Set Off Their Warnings.
Here's a How-To for R/R
IMPORTANT! AT THE END OF THE PROCEDURE, BE SURE YOU PUMP THE BRAKES PRIOR TO MOVING, THEN RE-FILL RESERVOIR IF NEEDED.
TEST BRAKES THOROUGHLY PRIOR TO ENTERING ROADWAYS.

Great write-up and eye-candy as usual.
May I just add to the benefit of those users who are thinking "but I don't HAVE all those tools at my disposal - I can't do this", I tried this on an early 463 and did not need the pad puller or piston spreader; you can improvise with a wedge, drift punch and drum brake service hook.
But having held that piston spreader in my hand, I must say there's little else like German engineering, even on tools! |

Yes, I fully understand your point, yet on the other hand I like to "stick to the book" on things. I don't want to encourage folks to "use a big screwdriver and press the piston back by prying against the rotor"...
I think there is a method to their madness. Is it worth bending the heat shield edge on the piston?
I'm not implying one needs to get high-end stuff.... One can get Piston Spreaders for $30 bucks.
My philosophy is, "IF I were to have someone else do it, they would charge me $X, if I do the job myself.... I can Treat my trolley to a new addition." |

For the Canucks in the crowd, the brake spreader can be purchased at Princess Auto for just under $30. And I know for a fact it works on the early 463 non-vented brakes. The brake pad puller would be nice, but that can be improvised on the spot. (read: vice-grip)
I suggest having extra pins on hand when doing the brakes. Mine had so much surface corrosion on them I had to use a dremel tool to remove them. |

Your title is slight misleading. The brake set up is for G500 or earlier G55 (not sure until which year)
Mine '05 G55 front brake set up is way different. You dont need a spreader, rather a *big* plier
to squeeze the pistons. The pistons are on the inside of the rotors only. I do have pics for this set up but havent find the time to post for public
consumption. |

There must be at least 3 different variations of G55 brakes since their launch in 1999/2000 - I think these are the 2000-2004 model? |

Well, since mine is 2004.... then the transition year must be 2005 for your updated version.
I encourage you to post your photos, for compare/contrast. |

Is it safe to assume that 2000 - 2004 G55 front brakes are the same as G500?
I guess with the intro of G55K in 2005, MB had to upgraded the front brakes. |

Anybody have the rotor wear specification for the G55k rotors? My light is on at 54k. I see some wear in the rear rotors. Thanks. |
