I posted a couple of weeks ago about my front brake issue(hard lever). I replaced the plunger. The previous plunger had some rubber breakdown. My problem is stil present. With the bike off, my front brake lever feels and operates normally. When i turn on the ignition it becomes hard to depress, almost like there is pressure being applied. Kind of like the system is fighting me. Rear brakes are fine. Any ideas what can be causing this odd behaviour? I have a 2009 SG w/ ABS. Also, after squeezing the lever and overcoming the pressure it works okay until the bikes off or after no use, then the hard lever comes back.
No help?

TIA,
Malcolm

 

Bump for help...

 

No experience with it myself, but there are some posts of similar issues being an ABS valve:

I strongly recommend a dealer for this issue.

 

Sorry, can't help you with your problem. Thought I would respond to keep your post current. Sometimes hard to get the correct response on the weekend, lots are out riding. Be patient, someone will come along with experience eventually.
Good luck.

 

My bet would be the ABS unit as well, it has independent valves for front and rear. Definately a dealer item as recommended before. Keep us posted.

 

Question: When the lever is hard, do you not have front brakes? Just wondering if one of the ABS failure modes might make the brake inoperative. The standard failure mode is normal brakes with no ABS. If your malfunction turns out to be the ABS taking the brakes away from you, this should generate a recall when they get it figured out.

This could be the old saying, if your bike won't go, that's bad. If it won't stop, that's way worse.

Typically your symptom is caused by the equalization port in the master cylinder being plugged up, but that stays the same regardless of whether the master switch is on or off. With your problem being only when the power is on, your guess seems as good as any.

 

Only very very hard initially then returns later. brakes are operative "most" of the time. I say most because when it gets hard to depress you have NO front brakes.

 

Best advise take it to the dealer or large independant. Your going to need a scanner to look at the sensors and control unit to see what is not logical
Good luck

 

Don't try to lowball the cost on a brake repair. Most of your stopping power is the front brake which I'm sure you are aware of.

 

I know w/out a doubt. Just trying to save myself a stealership visit. The dealer said they can flush the front or rear for $47.00. My abs doesn't indicate a problem. I'm hoping a flush will do the trick.
