The ABS system on the Scout needs a special tool to bleed it if you've undone any banjo connector. The tool holds the valves in the ABS unit open, otherwise it won't bleed. It's a dealer job unfortunately.
Thank you for the feedback. However, Prior to this issue, I had replaced the original handlebars with the Indian Mini Apes 10" which involved replacing the entire brake line from the master cylinder to the ABS module. Big pain in the butt to do. That mod was successful in that once install was completed all I had to do was bleed brake system as normal and I was off riding with everything working perfectly. So at first thoughts, I would have agreed with the "special tool" idea, but I have replaced brake line 2 times prior with no issues.
I have confirmed that from the banjo fitting on ABS all the way to the banjo fitting on the master cylinder is undamaged and no kinks or indentation in the brake line, nothing pinching it.
Also, even more confusing is that upon starting the bike and putting it into 1st gear once the speed gets going the ABS indicator light goes off (this is normal operating procedure) as if nothing is wrong, but I still have no front brake response. The pistons do not move in the caliper. I tried the air compressor test with success having both pistons respond, 1 easier than the other but both eventually coming out as designed.
Question? I have heard that the master cylinder if damaged or faulty will cause a brake issue. And stupidly I accidentally dropped the master cylinder on the garage floor. After inspection, it appears that it was only cosmetic damage and nothing mechanical. The question is could that 4-5 ft impact be enough to cause all this trouble? I did take off the master cylinder to inspect it and perform some checks and it does seem to have propper suction/pressure.
I'm at a loss as a simpleton garage mechanic. I'm not sure what more I can do as far as troubleshooting and testing.
I spoke to local Indian service shop (Daytona Beach, FL) and the only option they gave me was to bring it in and have a technician perform brake bleed in the shop and go from there. I was told the technician would have to plug into the ABS module in order to communicate with the bike's braking system in order to diagnose any possible issues. Not looking forward to having someone work on my bike or paying the hefty shop charges. Any ideas or advice is greatly appreciated. And thank you again for your input.
