As others have mentioned here, that's only a problem in changing weather. If it 
is consistently cold, the brake will not freeze.

I say this with 18 years of ski instruction experience, parking every winter 
weekend. I only had my brake freeze a couple times, when I had do drive up 
through slush into frozen country, then park the entire weekend. A bit of 
popping the clutch forward and reverse freed it.

 The first priority for society as a whole is to drastically reduce 
consumption of fossil fuel energy and products derived from fossil fuels. The 
key action is to curtail. That means buying less, using less, wanting less and 
wasting less. To curtail means to cut back or to downsize. Curtail reflects the 
seriousness of the current situation more than the politically acceptable word 
"conserve." -- Pat Murphy

It will still move, a motor with magnets will move slower since any EMF
generated will cause a large current (short circuited generator) that
counter-acts the movement, but the reaction is proportional to the speed
of movement, so at slow speed there will hardly be any counter-action
and the vehicle will still roll away, not be held by a short circuited
motor.
NOTE that this is only the case for motors with an active excitation
such
as a PM (Permanent Magnet) motor. Any motor without active field will
not
generate any voltage, so whether shorted or not, so you can turn an ACIM
(AC Induction motor) for example as much as you like, it makes no
difference if it is shorted or not.

Re: [EVDL] winter parking brake

2014-06-20 Thread Cor van de Water via EV 
I used the hand brake often while driving in The Netherlands
(same latitude as south Canada) and only had an issue once.
Remember that the time brakes will freeze to the rotors/drums
is when they are *wet* before parking. If you noticed that you run
through
something wet (puddle) before parking, you can drive the car another
block
with the brakes lightly applied (pull the hand brake until it starts
slowing down the vehicle) so it gets warm and the brakes dry, before
parking.

The one time I noticed was after a bright cold winter night, the car
would not move backwards, only "upwards". It had frozen on one side.
Jogging the car carefully back and forth cracked the drum brake loose
and I could drive normally after that.

When you're at -30 there is likely near zero humidity.  On the other 
hand, in temps from 20-30 there is much higher humidity and I would 
think brake freezing would be more likely.  It's only happened to me a 
few times.  I found that by rocking the car forward and back, gently, 
they eventually freed up.  Hard to do on ice, though.

Re: [EVDL] winter parking brake

2014-06-20 Thread Roland via EV 
I drive in a city like Fresco with steep hills.  My EV had a manual 
transmission where I park down hill, I would turn the wheels to the right and 
apply the parking brakes even in temperatures down to 33 below.  
If I park on a up hill street, I than turn the wheels to the left and apply 
the the parking brakes.  
In some cases I would not apply the parking brake when my tires are against 
the the street curbs.

What also helps, is to put the transmission in reversed gear on a down hill 
or in 1st gear in up hill.  In either of these gears, the overall gear ratio is 
over 15:1 or greater which will adds some resistance. 

The wheel chocks does not work so great, because I had to move the EV off 
the chocks to relieved the pressure and take a chance to retrieved them.

Another thing that could be done, is a mechanical mechanism to apply a 
locking key into the pilot shaft of motor if it has one. 

Do not use the brakes so much where it will heat up the pads.  I avoid 
using the brakes when coming to a stop.  This will allow the air to cool the 
brakes.

Re: [EVDL] winter parking brake

2014-06-20 Thread SLPinfo.org via EV 
Although I  now live in Oregon,  I grew up in northern Alberta Canada where
temps can get to -30 for extended periods in the winter.  I remember
hearing the "brake will freeze" thing but I  also regularly used it in my
manual transmission vehicles.   Like Michael I never had a problem.

Re: [EVDL] winter parking brake

Medium duty trucks used to have drive shaft brakes that could be cobbled
from junkyard parts.

I use the hand brake on all manner of vehicles (yes, sometimes up north in
the winter).  I do not find this to be a problem.  Is this just habit based
on older vehicles?  I seem to remember having to jog some truck other to
get the rear wheels to turn, but I didn't quit using the E brake all
together and the problem was not chronic.

Another alternative is to turn your wheels so thy hit the curb.  You need a
little incline for this.

Or instead of chocks you can swing a 4 foot length of chain around a wheel
so it wraps into the crack fore and aft the contact patch.

There is an adapter plate with a parking paw in it which slots into a ratchet to
keep the vehicle from rolling.
See http://www.tucsonev.com/EVstuff.html scroll down to 4 for some pictures
(it's still for sale, cheap)

Re: [EVDL] winter parking brake

Some factory conversions like the US Electricar
have added the shifter from the automatic gearbox version,
as well as the parking pawl that drops into the teeth on
the flywheel IIRC, the rest of the shifter is unused except
for operating a switch that tells the controller whether it
needs to move the vehicle forward or reverse (and it can
activate different regen settings for the different forward 
"gear" selection positions).

For a home conversion - I don't know. Carry a cobblestone to
place in front of the wheel?

My question concerns manual transmissions and parking in the winter.  We
don't use a parking brake in the winter here since the pads and shoes
freeze

others done?
