Rear Disk Weirdness

[Steadynow]

Just a FYI

If you let your rear disk get too thin... it confuses the electronics somehow. don't know why.

but that was the overview from BMW after i was stranded on the hard shoulder, as every time i rolled off the throttle the bike braked HARD. then capped my revs to 4k. in Race mode. TC light flashing

after some calls, i put in Slick and tried, & it was ok again albeit with TC light going mad. (didn't help in the pissing rain)

new Galfer disk & pads going on today. (OEMs rear was eye watering)

The ABS sensor ring isn't affected by the thickness of the disk... what that deuce?

 

[Steadynow]

indeed...could be cruddy speed sensor maybe..

I'm with Alex on that, the sensor pick up counts the magnetic pulses, clean the ring and pull the sensor and clean and inspect.

 

[Steadynow]

I've unloaded half a can of brake cleaner on it. The high end of my mechanical ability

 

[paul_m]

Pull the wheel out, unbolt the sensor of you can, of not clean it from the rear with soapy water and rag, then a drop of cleaner. Just hosing it down won't really achieve anything.

Wheel Speed Sensor

I had a similar issue with the front wheel speed sensor and all it needed was a good clean.

 

[Steadynow]

lets hope that sorts it... did it again today. slowed me to 40mph on the motorway. full throttle...

I've practised getting into slick mode without looking down now!

 

[alex]

That's about as much fun as when mine would cut out at random.
Get it in a shop if you're not mechanically minded.

just splurged on x2 tyres and rear disks / pads / chain & sprockets...

Could have done you standard Chain and sprockets cheap, if you have not already had delivered.

50 for the lot, would only need a new soft link.

 

[Steadynow]

thanks mate. already got them on..hence the tightness! :concern:

next time

 

[Steadynow]

on the weirdness note. Brake cleaner on the wheel speed sensors seems to have solved the power cut issue..... must keep her cleaner i guess!..

bloody winter

 

[Steadynow]

Saga ended.

Wasn't wheel speed sensors after all.

had a nasty front end lock up... kept it upright but blooming hell. That woke me up.

was a front caliper issue. it bound on... :culpability:

caliper clean and new pads later... all good.
