The computer controls the braking and prevents the pads from closing unless the brake pedal is applied. To disengage the pump you must hook up the computer and have it release the brake pressure. After you change the pads/rotors you need to activate the braking system and calibrate it to the new pads/rotors.
If you do not have this system then it is fairly easy and similiar to the other common braking systems used.How to change brake pads for ml350?
I believe that you should drive to the nearest Mercedes service center. Hand your keys to the man/woman behind the counter and ask the same question. Hand them your credit card and wait approximately 1 hour. Finally drive home. Repeat as necessary.How to change brake pads for ml350?
go to a brake mechanic
It's pretty much the same as any other car. The only thing special is that they have brake wear sensors ($2.00 piece of wire and plastic) that need to be replaced when you do the brakes. I think there are two on an ML, although it could be four.
On the fronts, you unbolt the calipers from the back. Two bolts, then pull the caliper right off. The pads come out the bottom of the caliper. Crack open the bleeder and push the pistons back into the caliper. Use a wire coathanger to support the caliper while you work on the rotor. The rotors have small allen screws that hold them in position..one on each rotor, I think they're 6mm. Unscrew them, pull off the rotor, and put your new one on. Back to the calipers. Insert the pads from the bottom, installing the wear sensors. Slide the caliper back in place. You should use new bolts to reinstall it, although I rarely do.
The rears are similar, except the calipers are fixed, and the pads are removed by driving out the support pins with a 5mm punch. On the rears, you may have to beat the rotor hubs with a nice big hammer to get the old rotors free of the parking brake.
Once your done, bleed and flush the system with fresh brake fluid, topping off the reservoir.
any mechanic can do that for you
