2000 ML320 Brakes

I just put new pads on front and rear of my 2000 ml320. It has ~73,000 miles and I believe that they were the original. I do have quite a soft pedal still. Can someone please tell me the wrench size needed to bleed the brakes? I assume that the only way to do this is have someone hold the brake pedal down while I get a DOT 4 brake fluid shower on each wheel? If there is a cleaner, more efficient way, it would be much appreciated. I was please with the overall ease of changing out the pads.

RE: 2000 ML320 Brakes

Hi, Naffs, welcome to the forum.

Coupla' questions for you.

First, was the soft pedal the reason for swapping the brakes or were they worn out?

Second, has the fluid system been opened such that air could have gotten in there?

Third, when you pump the brake pedal, does it get higher and firmer?

If the answer to the second and third questions is no, then I doubt bleeding the brakes would have an effect on your issue. If you've never had the brake fluid flushed that is recommended every 2-3 years, so that would be one thing to consider.

Also, did you clean up your rotors when you did the brakes? If the soft pedal is from glaze, swapping the pads would have little effect on the feel.

Anyway, that's some stuff to look at.

Take care and enjoy the ride,

Thanks for the response. The reason for changing was that the pads were down to the point that they needed to be changed. Actually, the feel in the pedal is very similar to the original feel. I have opened and checked the fluid in the reservoir in the engine compartment. And no, I did not wipe the rotors prior to placing new pads on. From prior experience, bleeding seems to firm up the pedal. Searching for an answer.
