Change of brake fluid

[t_marat]

I am going to change the brake and clutch fluid. As far as I know they are the same.
I read in bmwe34.net that the order should be rear right, rear left, front right and front left. However, for the clutch, where is the bleeding screw (or whatever) is located? Anything special I should look out for? Mine is a rh with manual transmission.

I don't have any problems with brakes or clutch. But I think the fluid has not been changed for at least two years.

Part 15

Looks like the fluid is seperate from the brake system. I had always thought it was the same.. part 24 looks like a seperate reservoir.

From bmwe34.net it seems like they share the reservoir.

On the 540 there is a separate reservoir for the clutch. Not sure of others.

I looked up an early euro build 520i RHD in real oem. The RHD looks like the reason for the extra reservoir.
Realoem does not list the reservoir in the part list for the same build date LHD car.

Is the brake booster on the right hand side of a RHD car? If so they probably didnt want to run a line that far to reach the clutch.

I am planning to put in Castrol DOT4 brake fluid. I also saw a DOT3/4 Valvoline fluid, cheaper. Guess the Castrol one is better?

You are talking about your brakes. Dosent take that much fluid to do the change. Pay for the one that makes you feel safer.

Didn't think of the obvious. How much fluid will I need?

get 2 quarts. 1 can do it but if you over bleed you may run out.

I think I went through about 24oz or two little bottles doing mine(wasted a good bit in the process).
Buy 1 more than you think you might use and return it if you dont use it.
