Help on bleeding brakes

3449 Views 11 Replies 6 Participants Last post by  DrBimmer
Put 330i brakes on my 323ci along with stainless steel brake lines, my pedal is now too soft. do I need to rebleed the system or put on a 330i master cylinder. If I rebleed has anyone used a vacum system, what special steps should I take, or is the use of a pressure bleeder the only way to bleed the lines.
thanks

Bentleys might have a procedure

If I remember I will look this procedure up in the Bentleys manual tonight. Otherwise email me and I can scan it as a picture and send it to you.

Bleeding the ABS/DSC module

I would say that the reason for this warning is to make sure that the system is bled properly to ensure no air is trapped in the system as this guy is feeling with his spongy pedal. The computer probably cycles the valves inside the ABS/DSC module to ensure that all air trapped inside it is released and bled out. I'm sure that you can do it the "old-fashioned" way as many have described here it just may take longer and not completely flush out all the old stuff. Myself, personally, I will let the dealer change the fluid with new stuff after two years so that I know it is done properly. Having the peace of mind that my ABS/DSC system is working properly is worth the couple dollars I might save otherwise.
