I bought a front/rear set of the drilled and slotted rotors for my '05 E500 and curious what is involved with installing them? I recently did this on my GS430 and it was very simple. If anyone has done this upgrade, please let me know if there are any simple tools required and if it is a straight forward swap.

Thanks,
Todd

Funny I just did brakes on a 07 GS350 very similar except you have Bolts instead of lug nuts and Torx bolts instead of regular bolts for the caliper. Doing pads too or not?

Just rotors this time. The previous owner installed some nice Hawk pads so, I'll leave them alone for now.

it is a easy job

My questions are short and sweet:

1)As long as I don't open the doors during the work, do I need to disconnect any of the electrical connections to the brake system under the hood?

2)Can I push the pistons in with a regular C clamp or is a special tool needed?

3)Do I have to remove the brake pad sensors for just a rotor swap?

Thanks,

1) I disconnected the SBC and still didn't open doors, etc.
2) yes, but please open the bleeder screw so you don't push that fluid back into the system as most people do.
3) You can leave them in, but you'll need to disconnect the cable to them so you can move the caliper around.

When finished, reconnect the SBC and hit the brake pedal to activate the SBC and it will reposition the pads for you, and you won't have any warning lights on the dash.

Also, when did you have the brake fluid flushed? It's supposed to be done every 2 years for DOT 4+ (or Super DOT 4, depending where you live in the world). If you haven't had it done, this would be a good time to do it and to add the Motive power bleeder to your tool collection (my favorite, but there are other products around).

Search around on the forum, as many people have already done this.

What happens if I don't disconnect the SBC? I assume this is the electrical connection to the brake system under the hood, right?

Thanks,

I have done the front rotors on my E320 (as well as brake pads) and the only tool you will need extra is a screwdriver with a head like a star. As long as you have one of those screwdrivers with a pack of different heads you'll be fine.

Also just one side note, when I did my fronts, they were rusted on pretty good so I had to hit em a few times with a sledge hammer. I did also consult a mechanic before doing so!

I disconnected it as an extra precaution to eliminate any signals going to the pump -- it's easy enough to do, just pull up on the connector sliding bracket and don't try and pull the connector off -- when the slider comes up it will disconnect the connector.

Also, as Merked E320 mentioned, the front rotors may be rusted to the hubs (mine were). Before installing the new rotors, clean the hubs and apply either some brake grease or anti-seize to the surface (don't go overboard with this) of the hub.
