Only good thing about riding
in all weathers is that it will boost your riding skill and ability to
cope with the unexpected.

Just try to relax, look ahead of you and gently accelerate out of the
bends. I'm thinking of taking one of the advanced riding courses with
my missus now that she's passed her test. You might want to try one too
everyone says they're great confidence builders.

Last weekend I took the advanced rider training and it rained all afternoon
while we were out on the bikes. They first had us get up to 25 mph and
then lock the back brake up, I guess so we would know what it felt like.
Then they had us get up to 25 mph and stop as fast as we could using both
brakes without locking up either wheel. I found out I use too much back
brake. After 4 or 5 tries, I discovered that I could stop pretty fast
on the wet pavement without locking up. They also had us doing some cornering
and swerving exercises that I would have never attempted on my own on
wet pavement, but everything went very well. Overall, it was a great experience
and I have a lot more confidence riding in the rain now.

You're much more likely to get into trouble locking up your rear brake.
You should get in the habit of relying mostly on your front brake - especially
in wet conditions. I only use the rear when I'm coasting to a stop at
a light or in the garage.

You really should use the rear too, all the time, the rear provides about
20% of the stopping power, and using only the front will mean that eventually
the back tire's gonna try to pass the front.
Ronn (San Diego)
Not really, Bill. The rear SHOULD provide about 20% of the stopping power
(under normal conditions over 20mph). As for the "back tire's gonna try
to pass the front" you may be referring to high-siding which is caused
by using too much rear brake (losing traction) then releasing. (see following
from Jim Davis' tips site at http://home.earthlink.net/~eca/TIP001.html
)
"To begin with, a high-side starts when you use so much
rear brake pressure that you lock your rear wheel. If you are in a curve,
or if you have also applied your front brake while going in a straight
line, or if there is substantial road camber, or severely unbalanced loading
of the motorcycle, this starts the rear end sliding/skewing away from
the direction the bike had been moving because traction is diminished
on the rear tire. (It has become 'sliding friction' - about 80% of what
it was just prior to the skid.) That tire has begun to MOVE FASTER (in
the direction of bike movement) than the front tire (centrifugal force,
among others, is having its way.) The automatic, and correct, driver response
to this situation is to turn the front wheel in the direction of the slide.
[Actually, the front wheel will turn in the direction of the slide by
itself - your job is merely to let it.] But now he can make a mistake
that can cost him his life - he can release the rear brake..."
I don't recommend using ONLY the front brake. I recommend
using MAINLY the front brake. 80% qualifies as mainly. The majority of
riders I watch next to me on the freeway etc. seem to go for the rear
first, as a reflex, and then the front as an afterthought. Could be a
dangerous reflex if they're overzealous in a crisis. Your results may
vary. Action figures sold separately.
Bill Hamm - ISRA#729
While indeed using the back too much can lead to premature lockup of the
rear and that'll certainly caused it to skid, and could lead to a high-side
(bad thing), it's not the only way the back of the bike can try to pass
the front. Specially in a curve on less than ideal surfaces, if the back
isn't braking with the front, the momentum (remembering that all the bike's
mass is behind the braking front wheel) can also cause a skid just cause
the rear of the bike is not being slowed at the same rate.

to use the most effective stopping procedures all the time.

The front brake is best because when you start the braking process, the
weight of the bike shifts forward, away from the rear wheel. The front
of the bike gets heavier, the rear lighter, which means that the rear
wheel is easier to lock up, which is bad, because it's easier to lose
control of the bike if the rear is locked up. When you lock up the rear,
you lose the gyroscopic action of the spinning wheel. The rear end of
the bike starts to overtake the front. If you're not trained to deal with
this, it can end up in a low side, or worse, a high side crash. If you
lock up the front, there isn't time to deal with it. You're on the ground.
Period. So if you were to have a choice on which wheel to lock up, I suppose
the rear would be the best one. But it'd be a dumb choice, because you
should never lock up either wheel. Keep them on the ground and spinning.
That way you've got max control, max braking power. You should apply the
front brake gradually, giving the chassis time to settle in to crouch,
the front end compresses applying more weight onto the front tire. Remember
the rear is lightening up so stay off the rear brake or it might lock
up. It's ok to use a little rear, but be careful. Once the bike is crouched
toward the front end, you can apply quite a lot of force to the front
brake without much fear of locking up. Just remember that it's a lot easier
to lock up the front on wet or other slippery (sand, gravel, oil, whatever)
surface than on dry asphalt, so when things are slippery, you've really
got to adjust your speed to the conditions. You won't get much warning
when that front locks up. Usually what happens is that something happens
in front of you, you flinch and grab too much front brake, and the next
thing you know you're nursing road rash and repairing a busted bike.
Bill Hamm - ISRA#729
Pat, great answer, but with the cruiser the weight transfer isn't as much
as with a standard bike or a sport bike, due to the geometry of the frame.
There's alot more weight on the back on a cruiser to start with than most
other bike designs, so more stays on the back in braking. Also meaning
you have to use even more care with the very powerful disk front brake,
specially in less than ideal riding conditions. An advantage of high weight
transfer in braking is that the more highly loaded the front wheel becomes,
it can proportionally accept more braking without locking. So you can
gradually increase the braking effort without locking the brake. Same
deal with wet surfaces, takes relatively less brake to lock the wheel.

Just an interesting note: Back when I took my MSF course, I mentioned
to the instructor that I had a bad habit of only using the front brake.
He said that was much better than only using the back brake.
Jeff
One bit of advice I haven't noticed in this thread (I may have overlooked
it) is how to handle a rear wheel lock-up. If you do by some chance lock
up the rear wheel, DO NOT get off the brake, particularly if you are moving
pretty fast. When the wheel locks, then starts rotating again, you are
likely to high-side it. The best thing to do is squeeze the brake harder
to make certain it stays locked, then skid to a stop. You may flat-spot
the tire, but that's better than flat-spotting body parts.
Bill Hamm - ISRA#729
Jeff, semantics maybe but: You should say press the brake harder, you
can't squeeze the rear brake, saying to squeeze it may make some new rider
think to squeeze the front more, which would be a bad thing.

Really, I have a couple of questions, since the front brake provides 80%
and the back brake 20% of the stopping power are the brake peddle/levers
set up so that you have to use 80/20 force of do you use the same force
on both? When I went down (high sided) in the rain, I didn't have time
to do what most of these posts suggest. It was stop this instant or get
kissed between two cars, period. Taking evasive maneuvers to the shoulder
of the road while trying to stop in a downpour put me on the ground in
a heartbeat. I'm not sure what I should have done in my situation or how
to brake in a real emergency where you don't have time to slowly "squeeze"
the brake till you stop.

Sandy, you make a good point, when the time comes to use the infomation
here you really don't have time to think about it. Someone made the comment
that what you do in an emergency is the same things you do all the time,
this is because of habit. Using both brakes all the time, more pressure
on the front, applying the pressure steady and increasing as the tires
react to the conditions, etc. Do these as a regular routine and the chances
are pretty good that habit will give you the best chance.
Anon-
Sandy, you don't have time to gently squeeze until you've approached the
bike's limits. What happened to you is very common. We have to get used
to our bikes in all riding conditions, and learn their limits. You were
unlucky enough to find one of your bike's limits the hard way. Practicing
braking in an empty parking lot (dry and wet) is a good idea for anyone
who is either new to riding, new to a particular bike, or just getting
back into riding after a break. The unfortunate thing is that you may
have done everything right. Sometimes the circumstances we end up in screw
us no matter what we do. I'm convinced that the best way to be safer is
to ride more. That's the only way to get to know the bike well enough
to ride it to its limits when we have to.
Bill Hamm - ISRA#729
Sandy, In the exact same situation, I don't think anyone could have done
anything differently. But, if you were riding defensively enough, you'd
not have been in that exact situation in the first place. Since you can't
brake in wet conditions like you can in dry, you need to allow a lot more
room between you and other vehicles. Your emergency braking will likely
equal a cars in heavy rain, this is a bunch more distance than you'd achieve
in dry conditions. Everyone the grand majority of time, me too, rides
not defensively btw, it's not a new thing. Have you ever thought while
going around a tight corner, that you can't see all the way around, what
you'd do if you came upon a stopped car? The odds are you're going too
fast to stop, if the other lane was blocked by oncoming traffic, then
you have a real emergency. Same thing for riding in traffic, if the car
in front of you suddenly stops, can you stop too? Maybe, maybe not, depends
a lot on how close you're following. Knowing what your limits are in all
weather conditions may just save your life someday.

Thanks to everyone for their contribution. I have tested many of the suggestions
and now feel far more confident to stop in different weather conditions
and in the shortest possible distance. Mainly i now know to use the front
and back brake in a 65/35 ratio or there-abouts in all conditions. To
look even further ahead for up coming hazards and have a better understanding
of not only my abilities but the bike and other road users too. Treat
everyone else as a complete idiot and you won't be surprised when they
try to screw up your day. I'm definitely going to go for an advanced riding
course in the near future.
