ABS defeated by leaves.

Riding home down Westferry Rd last night following a bus at a gentle
pace.

Bus brakes, so do I, gently.

Front wheel goes over a patch of fallen leaves (soggy), locks up as it
slides through onto the tarmac, where it remains locked.

Muggins releases pressure on the brake lever, and progress is resumed.

Linda was paying more attention than the ABS, and she didn't notice
either.

I presume there's an "effort" valve, or something?

 

when you say "gentle pace" what do you mean? All ABS will switch off once
you drop to a certain speed, typically walking pace.

If you were going faster then you might want to experiment and try to
provoke it, just to verify it works. The road from the BP garage at Malpas
to the M4 junction would be a good place as it has a 5 foot wide diesel
slick.

 

Erm, correct me if I'm wrong, but ABS means "Anti-lock braking
system". If your wheel locked then it suggests to me that you've a
problem with the ABS (unless you were going at crawling pace, as
wessie suggested).

In the past, I've had an experience of using my ABS brakes on wet
cardboard and it's did the job it was supposed to.

 

Slippy them leaves. I had a sphincter moment when the back stepped out
on the CBR11 on them.

I tend to agree. Worth having that checked. The BMW system deffo releases
and grabs again in those circumstances (drain covers)
