I have a 2005 E 320 with SBC. I just had a brake job and a brake fluid flush (115,000 miles) Not sure of how system link up but my brake pedal seems to have a softer feel. In conventional systems this is air. Not sure it's applicable in this brake by wire system. Anyone know?

 

bump, any thoughts ?

Thanks

 

I had the dealer bleed my brakes on my e320 and did not notice any difference. When I bled brakes on my motorcycle and Volvo I did notice some sponginess for a week or so. I say just drive and eventually any air in the system will find its way to the master cylinder. If it continues after two weeks, take it back to where you had it bled and have them re do it.

You shouldn't notice any difference in pedal feel. The brake pedal isn't mechanically connected to the hydraulic system, it works like the drive by wire system you gas pedal uses.
