ABS power Brake Problem Solved

I have a K1200RS, 2004, with at the time 20,000 miles.

Sometimes, (a mechanicís worst type of repair) sometimes when I would start the bike the brake warning light would blink fast and I would not have power brakes. When this happened I would ride the bike for about 1 to 2 miles or 50 feet it and the light would go out and the brakes would work correctly and be fine, till I turned off the key switch.

This problem continued for months. I could not get to a dealer. Sometimes the brakes would work fine for weeks; the brake light would just go out after a few feet of ridding just like it should.

Then I had the brake lever clevis clip fall off and I had no rear brakes. That was a little concerning at one stop light. That is what lead me to the sticky brake lever bushing problem.

The problem was the foot brake lever. I am one of those guys that only use the foot brake maybe at a stop light.
Well, the foot brake light switch has a double contact it seems. One for the brake light and one for the EBS and power brakes sensor. The foot brake lever has a self lubricating bronze bushing that after time was sticky. The brake lever return spring would not fully return the pedal. The brake light was off but the EBS signal was on. Thus, no power ABS brakes.

The fix was easy and at no cost because I did the work. I removed the foot brake lever, cleaned and lubricated the pivot bushing.

So there you are, one more think to worry about.

It's not just ABS problems with this type of fault:

When gear/brake/starter/stand safety interlocks stop working, you can find a worn pivot bushing in the clutch lever which stops the microswitch in the housing from operating. The system doesn't register that the clutch has been pulled - so you end up getting the bike to start in gear - which it shouldn't.

Talking Thank You!!!!!!!!!

dear Fllash! Thank you, by reading your post I was able to fix a similar problem on my K1200RS 2003 model. When I looked where you said I found a broken spring. Costed me $8 to replace! Had I taken it to the dealer, he would have replaced the ABS first, then perhaps would have found the problem, but wouldn't tell me - things like that do happen unfortunately
