breaking in brakes...what do you do
Just had all the brakes done on my vehicle. Vehicle brakes, as we all know are very important on vehicles, but IMO....more so on a tow vehicle. How do you break in your tow vehicle brakes ? I'm ...

formal name of the process is 'bedding in', best article used to be

Short answer is that is to both cure the friction material and smear
friction material that has out-gassed onto the cast-iron (condense
onto it)
Best braking is friction material on friction material
You can bake on high spots and that will be 'felt' on the brake pedal
and so many think warped rotors...I think 50% of the time correct, but
other 50% it's high spots from stopping while friction material is
out-gassing
not many understand 'out-gassing' of friction material and the high
spot issue
I do NOT agree with them that there is no such thing as warped rotors
They used to have a section on that and have not read their stuff
in a while
Out-gassing is the main reason for 'drilled' rotors (racer stuff and
no business for street use), slotted rotors (good) and slots on
the friction material (us boy racers used to hack saw a slot before
they came with them from the pad OEM). Cast in or molded in (carbon
fiber rotors) holes are good
The reason for those hole/slots/etc are to allow the out-gas a way
to get out and not 'float' the friction material off the cast-iron
Think hydroplaning tires or water skiing
There are many methods, but they all boil down to getting the friction
material hot enough to cure (must hold it there and cycle down to
a cool down temp and then get them hot enough to out-gas. That then
condense onto the cast-iron
DO NOT stop rolling while the friction material is still out-gassing
As that will bake high spots
DO NOT over heat, as the friction material might degrade quicker
If done right, better than on plain cast-iron...that site above has
a good write-up (used to, haven't poked around there for a while)
Good write-ups are all over the Internet, but so are bad and mediocre
write-ups...gotta figure out which is best for 'you'...me, used to design
industrial controls and one aspect were both drum and disc brakes. So
learned a bit about braking...plus used to race a bit too
