we keep hearing 'Harley engineers', but I have to wonder, how much of this is on Harley and how much is on bosch?
@stixvrad when he says, front brake at 10%, he isn't referring to the pads, he's referring to the operating efficiency.

I'm not trying to be argumentative but if the efficiency was what they were referring to , "failed" , "hydraulic failure", inoperative" would be a word used, not "gone".
Maybe the OP just had an idiot as a service writer who cant translate mechanical conditions into words.

Hey OP, I would like to hear more details about what was done to repair the bike. New ABS module? Pad replacement? Bleed brakes and go? We're missing some details that would be helpful. Any chance you can detail out what the dealership did to get you back on the road?

Engineers design it. Accountants reduce cost to sell it. Wether reliability or usability suffers doesn't matter as the lawyers say the profits will exceed the liability.

Only very slightly, and under tremendous pressure. For all intent and purpose, it does not compress.

I suppose it depends on the type of failure (keeps your pedal and grip disengaged), but if true in any situation, then yes, it's a **** poor design.

Im not sure what the protocol is on a bike but on a car when you start it, the ECU does an electrical test (you need to move the bike to complete this test) and turns off the light if theres no fault found on that side of the system. Once rolling it'll cycle the hydraulic pump and I believe the spool valves but you don't feel this because your foot isnt on the brake when it does it. You could hear the pump do this on older fords when I was a Ford tech. Makes me think that regular exercising of the HCU on cars and trucks could be the difference if HD doesn't do this simple blip of the hydraulic side. Now maybe it does do this, a HD tech would know for sure.

I'm thinking you could feel a slight pulse in the brake lever/pedal at startup if that were the case. I can feel the pulses during an ABS event. Never felt it at startup, but if it was just one pulse initiated by a system check, it may be undetectable.
I knew you knew that - but didn't want it to lead someone else the wrong way.

I like harleys cause I can work on them. But I hope time marches on and ends up like my truck. You shouldn't touch it other than maybe pads for 100k. I do lots of highway riding. If bikes get that, way I suppose I would be ok bringing in for work.

True. There used to be shirt shold in jap catalugues, if they had as many engineers as lawyers they would have a better bike. Always thought that was funny.
WTF do they go?
