Has any one ever used ATE Super Blue Brake Fluid in the Merc? When they serviced my E320 they used OEM. I have used this in my old BMW, but was curious if anyone is using this is there MB? Lately I have been in a lot of stop and go traffic and I noticed the brakes seem a little soft after awhile? Any thought would be appreciated.

We'll I sure hope they did, it was at the dealership here in town. The has always treated me good. It's only been 2100 miles since the service, I will call them in the morning and have them re-check it. I was thinking that maybe there was some air in the lines, but was hoping for the best.

It could be that there are a lot of brake fluids that will work, but if I were you, I'd stick with the OEM. That sounds like air in the system to me.

I have used Ate fluid for years but never liked the blue one just because it will not show the dirt and dissolved rubber as it ages as clear or yellow tinted one does. I try to follow the old Mercedes rule: "replace brake fluid once a year, preferably in the spring."

OEM is probably Ate or Pentosin.

Next time I'll be trying DOT 5.1.

Cheers

wow, replace it once a year? is there an easy DIY, wouldn't want to have to pay for this on an annual basis? i got my car a year ago and they did service the brake fluid before i bought the car, so maybe in the spring i'll give it a go.

Brake fluid on the 210 chassis is every two years and using a pressure bleeder is the preferred method. On older Mercedes it was once a year.

I used oil extractor to help flushing the brakes. With ABS it will not create enough vacuum to flush, but it will catch the fluid coming when you push the pedal and hold the air from going in. Pressure bleeder might be nice toy, but expensive and I have mixed feeling about pressurizing old fluid reservoir to 35 psi.

is there a DIY on this? on the DIY scale of 1-10 how would you guys rate the job?

Can you squeeze toothpaste tube?
just kidding. The biggest problem with brake flushing is removing the wheels and cracking the bleeder loose. It is usually 8 mm hex, that is easy to screw if you don't have good quality wrench. With pressure bleeder the actual flushing is kids play.
