E320 stopping - PeachParts Mercedes-Benz Forum

I just changed my E320s front rotors and brake pads and flushed the brake fluid. Is it common for the car with a new set of brake pads and rotors to take a little longer for it to come to a stop. I hope I didn’t get air in the brake lines!!!

The peddle has a approximately 2" play but when I put some pressure on it the car comes to a gradual stop??? Has any one experienced something like this? Thanks all and Merry X-mas.

Is the pedal soft? Sounds like you didn't bleed the brakes properly.

no it seems normal.

Most brake jobs I've worked on require break in period and mating of surfaces. Don't think MBs are any different. Haven't had to perform a brake job on my
99 E320 yet.

When I replaced my front brakes on my E320 I did not notice any difference in stopping distance.

Whenever I do a brake job I also bleed the brake lines but I bleed all four brake lines not just the two I am replacing.

Did you clean off the protective coating on your new rotors? I use brake cleaner to remove the protective coating.

I also "break-in" the new brakes by gradually coming to a stop from 20 MPH, 35 MPH, 40 MPH, and 45 MPH allowing time between for the rotors to cool.

I bled all four brakes and I did clean the rotors and brakes with brake cleaner. The only thing that has me worried is that when I was bleeding the last one I lost track and I noticed that I only had a little bit of brake fluid in the reservoir. So I guess I’m worried that I got air in the lines. I haven’t really driven the car yet, I just went down the street and back, but I would know later on for sure.

Best to use a pressure bleeder when bleeding the brake lines. It has a reservoir of brake fliid to ensure that air isn't introduced into the system.
