Got the Dreaded ABS Red Brake Failure Light 2007 R1200RT
[B]The Bike:[/B] 2007 R1200RT 21K miles. Has had brake line and cable recall performed.
I am a little on the nauseated side as I write. I rode over to the in-laws yesterday evening and on the way the Brake Failure light blinked and then stayed on. Paranoia set in immediately, tried both the front and rear brakes independently and both worked but the rear seamed to require a little more pressure. I tested the brakes several times hoping it would reset or clear. On the way back home I realized that the ABS was not working, because I could lock up both the front and rear tires. After I arrived home I checked the front Brake fluid level via the sight glass and it was filled to the tip of the glass. I check the rear brake level and it was at the top. I check the brake lights and both lamps were working. I checked the cables from the rear Final drive and from the front sender unit and both appear to be without any physical damage. I started the bike and as it idled the brake failure light blinked like normal so I proceeded out of the drive the blinking brake failure light went out until I applied enough pressure to lock the rear tire and then the dreaded brake failure light came on and stayed on again. I have turned the key of and restarted the bike, however the failure light stays on. I disconnected the battery in an attempt to wipe the fault, but the light stayed on.
[B]Now for the $3500.00 question of the day. Is there anything else I can check prior to scheduling a service? [/B]
07 R1200RT ABS BRAKE FAILURE Update
[QUOTE=WestHautianPlen;791148]Thanks for all of the help. I checked the brake lights this morning and they both appeared to be ok, but I picked up new lamps for the break lights while I was in town and will change those out and clean the socket contacts tonight. I will inspect the front and rear sensor wiring also.
I will report back.[/QUOTE]
1) Changed rear brake lamps, both elements in the originals were ok.
2) Removed plastic, examined sensor wiring back to connectors, could not find any abrasions or even a potential to rub brake disk, cable keepers were all in place. Ok
3) Manipulated wiring associated with ABS termination board.
[B]Here is the sequence of test I tried to see what would happen:[/B]
1) Start the bike, Brake failure light flashes. Good
2) Pulled in front brake lever, pushed on rear brake lever while stationary, Brake failure light still flashes.
3) Shift into gear and take off down drive, Brake failure light go out. Good. Then out on to street.
4) Used both brakes front and rear several times no Brake failure light. Good
5) Did a couple of hard stops using front brake with no brake failure light.
Then Push on rear brake pedal with increased pressure each time until enough pressure was used to lock up rear wheel, and I then get the Brake Failure Light on Constant. Will not reset until bike sets for a while, in the instant case 1.5 hrs.
