Brake light, speedometer failures

2006 k12GT. Replaced the fluid in my FD recently and shortly thereafter got brake failure triangle with intermittent speedometer and cruise control stopped working. Speedometer has all together quit and what started as an occasional brake triangle is now solid with "brake failure" displayed. I confirmed ABS does not work and the rear brake only seems to require much more pressure to achieve normal stopping. Front brakes still work great minus ABS protection. I'm thinking the common denominator here is the speed sensor and it must have died when it was removed from the FD to refill the FD oil. Would someone sanity check me here. Thanks

First, check that the disc has not rubbed thru the wire, that comes from the ABS sensor at FD.

Re: Brake light, speedometer failures

Make sure the electrical connector is securely attached to the ABS modulator. It has a cam lever that secures it.

Re: Brake light, speedometer failures

Bearings in FD failing as evidenced by massive metal deposits in recently changed fluid. I think speed sensor problems are probably a result of all the metal caked to the sensor. After I fix the FD i'll see how it's working.
