2011 E70 35d - Hard brake pedal when in gear?
Hi,
For the last couple weeks I’ve noticed braking at slow speeds I need to press really hard on brake pedal even though it feels like it’s right to the floor?
From the research I’ve 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? What’s the best way to troubleshoot?
Thanks
