I am currently trying to bleed my brake system and have already completed the two front calipers without a problem. Although when I try to bleed the two rear drums I cannot get any fluid from the bleeder valve.
Do you
have the same problem?

Hi,

I'm not sure if you have ABS or not on the vehicle. I will provide the directions for both systems. However, let me know if anything was replaced prior to doing this procedure. Also, the attached pictures correlate with the directions.

Do you have ABS? If you do, the abs module needs to be placed into bleed mode. Let me know if you have ABS or not. That was an option according to my manual.
