BRK on

[deo]

Got the indicator that says BRK in the digital panel by the speedometer. I have new brakes, brake lines, and the brakes seem to work fine. Could it be a short or something along that line. What is the general procedure for checking that computer system?

same here

i've got the same thing going on my xj. i believe its the sending unit? switch whatever you want to call it. My brakes work well also fluid is up to snuff,so i'm leaning on the device that sends the signal?

Take a look at the calipers, mine were really dirty on the contact plates ( the stainless strips that are in the caliper by the edge of the brake pads, these only contact the brakes when the pads are worn or sticking in place or so my yamaha dealer tells me, I have not had any luck keeping mine off, i have used brake cleaer on the strip and had it go off for a while but it never stays off.

Correct! When you start the bike, the warning system "polls" (checks) the fluid level switches in each fluid reservoir. If both switches are "made" (closed) when the bike is started, the BRK warning light goes out after the bike starts. If one (or both) switches are not made (open), the warning light stays on. Each switch is a plastic post with a lightweight float that rides up and down on the post. I believe that inside the post is a reed switch, and if you look closely at the inside of the float, you will see a ring magnet. The magnet activates the reed switch when the float is in a certain position on the post. When the fluid is at the proper level in the reservoir, the switch is closed. I had a problem with the rear switch on my XJ, where the switch would not make with the fluid at the correct level. Luckily my parts bike had a good switch on it, and I was able to swap the switch and fix the problem. From what I understand, the switches are not available seperately. At least they aren't shown seperately in the parts diagrams. You can disconnect the wires going to the switches and jumper across them to fool the warning system into thinking the switch is made, however you will need to keep an eye on the fluid level since you can't depend on the warning system to tell you the fluid is low. However, if the system isn't working anyway, it's a moot point!
