Hot wheel rims,hub and smell from axle

Wasn't in hopes of someone stating the laws of physics on this
topic...but now gotta state some facts

All friction braking has the friction material rub against something much
harder

That then has the friction material become sacrificial to that harder
material...meaning more of the friction material will be abraded off than
the harder material...in this case, the cast iron rotor or drum

There is kinetic energy in the moving vehicle/trailer and in order to
slow/stop that moving mass....that energy is converted to HEAT by the
friction material rubbing against the cast iron

Braking will ALWAYS create heat and braking down from a higher speed
will have HIGHER temps...each time...



Maybe best to link an older thread talking about this...


Trailer Brakes - How hot is TOO hot?

Do a search on brake pad MAXIMUM temperature or working temperature....that is
the temperature before it transitions to 'fade'...really getting so hot the
friction material out-gasses (smokes) to float the material off the cast iron

Below are the working temperatures for the friction material itself and the
cast iron temps will be a 'bit' less...but not much less and dependent on how
well they reject the heat

OEM/stock/mud-hen friction material's maximum WORKING temperature is around 280*C (536*F)

HD friction material's maximum WORKING temperature is around 400*C (752*F)

Performance friction material's maximum WORKING temperature is around 500*C (932*F)

For reference...to fry a T-Bone to medium-rare, the internal temp should be 125*F

Also note that there is a minimum working temperature...below that and
the braking will NOT be very good

So any of the above maximum working temperature will fry your fingers or even
have flesh stick to the cast iron brake material...


Careful of internet forum info...not all are accurate...suspect mine too and
do your own research. I've had mine actually bellow visible smoke...my 2 seater
on a track day, my Silverado and even my Suburban...

Here is a picture of a test run and note that the rotor is glowing...



Do a search here and other internet forums/sites...RAM IBC has an issue
reported and filed with The NHSTA

Trailer brakes 'should' have the ability to skid the tires...but also
well known/documented is that the trailer OEMs 'mostly' do NOT put in
the highest rated braking systems out there...and many disagree with
me on that based on their experience...but experience with OEM trailer
brakes... :R
