Brake Bleeding - How to Cycle ABS Valves?
 

Any anyone here figured out to cycle the ABS valves on our cars without a diagnostic tool? I know I can get a harder brake pedal feel but after boiling some fluids at the last track day and activating ABS a couple of times, I feel like air may have gotten into the ABS modules that I can't seem to get rid off after two bleeds (where no air came out on the last one). Brakes still work fine but not as firm as usual after a flush.

I've looked around and it seems like older Subaru models can self cycle per this thread: https://www.iwsti.com/forums/gd-gene...-problems.html

I'm wondering if such a self diagnostic mode exist for our cars. Otherwise I need to buy an OBD tool that will do that for me, and who wants to spend extra money on a tool when you can do it for free! Thanks.

Sounds like brake pads are toast. Not abs.

Yeah that’s not the issue. On the second flush I went to winter pads. Same issue.

That's an odd ball. Well, might want to spend some money on obd tool. Might want see what on sale on Black Friday.

Are there any dirt or gravel roads near you? Engage the abs a few times when it's safe to do so.
