Hey everybody,

I'm going to attempt a brake fluid change and wanted to get some reassurance from you guys about what I'm doing.

So to bleed the brakes I'll
1) Use turkey baster to remove brake fluid from reservoir
2) Fill reservoir with new fluid
3) Bleed the brakes from farthest to closest and use INPA to bleed module.
Correct? Am I missing something?

I also wanted to know what kind of brake fluid do you guys recommend and how much should I buy. My car is a 2004 525i m54

Thank you

I used the ATE Super Blue (1 can/Liter?) as mentioned in this thread and change approximately every 2 years.

IMO, the turkey baster step is unnecessary and you can just flush it all out the wheel rather than suck a little out.

If you never run the master cylinder dry, you don't need the INPA bleed procedure.

Also, if you have a manual transmission, there is a finer point. At least on my 530xi, the reservoir for the brakes and the clutch are the same tank. There is a partition inside the tank that goes most of the way to the top of the tank. That way, if the clutch line dumps out it's fluid, the fluid for the brakes doesn't go with it. If you bleed the clutch you need to have the reservoir filled all the way up without much or any air inside the reservoir. If you don't, the new brake fluid won't flow over the internal partition into the clutch side. I found that out the hard way
