P0572 Code: Brake Switch Low

P0572 Code: Brake Switch Low
I had a check engine light recently. The code displayed was P0572 brake switch low. Apparently the rear brake switch has failed causing the CEL as well as causing the cruise control to be inop and the brake light to remain on. I have unplugged the sensor so that the front brake switch will still activate the brake light and allow the cruise to still operate. I have the replacement part on order and will install the new part next week when I upgrade the exhaust. Anyone tackle this repair and if so, was it necessary to bleed the brake lines or the ABS module?
Thanks,
m.a.c.

Since the switch is fluid operated, I would imagine it would require bleeding the brakes. Mine was done under warranty on my 09. There ought to be a recall on this. More and more people are seeing this failure. I smelled fluid but could not going the leak because it doesn't leak until you apply the brakes and the switch goes under pressure

Nope just put some fluid in the new one, take the old one off and put the new one on quickly. Clean up any drips. Pump the bake a few times and you should be good to go. If you do get air in the ABS module you will need to take it to the dealer to put it on the digital tech to bleed. The above technique worked perfectly for me.

Check this too
After replacing the rear brake switch that was bad but didn't fix the problem I tore the bike apart, checked and tested both switches over and over again. Defeated I put the bike back together. Later I pulled up the full schematic to find that the brake light system shares power with the accessory system. Checked the fuse, it was blown, replaced the fuse. Problem fixed.
I did have a P0572 code and the brake light / cruise control was not working. Haven't ridden yet to see if the cruise works but I am sure it will be back.

Bleed the brakes. I don't care what trick or short cut you try, you are going to introduce air into the line.
They are what stops you, why take a chance on reduced braking when bleeding them is so easy?
And, no, you won't need to do the abs module as long as the switch is down stream of it.
