2011 E70 35d - Hard brake pedal when in gear?

Hi,

For the last couple weeks Iíve noticed braking at slow speeds I need to press really hard on brake pedal even though it feels like itís right to the floor?

From the research Iíve done it looks to be one of three things vacuum pump, vacuum line or brake booster. I know there was a recall on the 2007-2010 8 cylinder but it on other models.

Has anyone else had this issue? Whatís the best way to troubleshoot?

Thanks

Sorry, no help. I had a bad booster, similar feel. But on an E39


Dont just focus on x5s as you search


And be careful, dont be driving that car.

Hi thanks for response. Just curious did you just replace the brake booster or did you ask replace vacuum line and / or vacuum pump?
