Another one for the KB.
After having new pads fitted the brakes started to 'buzz' the ABS just as I was stopping. I could 'feel' it was coming from the nearside so lats night I took the wheel off, pulled the ABS sensor and found some 'crud' like swarf stuck to the front of the sensor, a good clean with brake cleaner of the sensor and a squirt and clean out of the loacting socket sorted it, total time about 20 mins most of which is finding the locking nut to take the wheel off
For info it just pulls out although a twist and wriggle was needed due to the crude .
No piccys as I was in a rush and it was going dark but seriously its dead simple...
