Hi All, need some help understanding what service my 2013 C-300 4MATIC needs. I'm at the 40K service mark, I changed the regular oil myself, and understand I have to have a transmission (including transfer case) fluid change.

However I have two questions:

• Do I also need to do the rear transmission fluid change (LSD)?
• How ofen is everyone really changing out the brake fluid?

Thanks in advance.

Brake fluid every 2 years (time not mileage). I changed my differential fluid at 100k miles
