After multiple brake fluid flushes and bleeding and still having a soft pedal (to the floor soft) I started looking for the cheapest bidirectional scan tool that would actually get any air out of the ABS system. After all the searching, my cheapskate self decided on the Foxwell NT630 Elite from Amazon. Yeah, it's from China and it's not going to program your keyfob but I just verified that it can run the ABS purge on my 1999 Blazer. The fact that they had a lightning deal drop the price to 118 bucks (normally 140) while deciding which one to get was just a happy accident. It dark outside now and I'll bleed all 4 wheels again tomorrow with the power bleeder but I thought I'd share a tool confirmed to bleed the ABS system is now under $150. It also does all the normal OBDII and airbag codes too.

 

If you get a chance post a link to it. I'd be interested in hearing how it works out for you.

It did perform the ABS bleed and it looks like it will cover the full range of 96-05 blazers for it (I selected 1999 obviously). I did get some more tiny bubbles and some trash out of the lines (metal flakes are bad, M'Kay!), and one of the bleeders clogged up on me so it turned into another flush.As far as getting to the ABS purge, it's not too hard, just not the most intuitive way to get there. Things to remember are: When it gives you a list of letters to scroll down, it wants the 5th digit of your VIN. Also (maybe more importantly depending on how you look at it), there are two completely different branches for checking the ABS/SRS (same 'button' to select). There's a choice of Body or Chassis, Body will send you through airbag side and Chassis will send you to ABS side. Make sure your battery is in good shape before you decide to perform that 2nd/3rd/4th auto purge too, it's a real battery drainer!

I'm at the point where it stops again but I'm going to replace the rear brake pads since the left rear looks close and it's making noises now. I'll know for sure if I need to reset the brake bias at that point.
