Brakes are a critical component and your points are valid.
My post wasn't to suggest that others may want to do the job and
I sure don't recommend others attempt it without a very good understanding
of the job.
As you point out Robert there are other factors that must be considered.
Wheel bearings are another critical part directly related but again, it wasn't
my intention to "disect" the procedures or many technical particulars.
I'll add that I grew up with a lot of hands on and fortunate to be around
some most professional mechanics - it was something I enjoyed learning
but no way was it with the desire to do full time as a pro.
I've built and rebuilt motors and completely rebuilt and restored muscle cars.
It is easy to not realize all the very important details envolved and mislead
another thinking there's not much to it.
In no way am I suggesting that others should attempt repairing their vehicle.
My intention was to point out the INSANE price quoting for this particular job and
by major vehicle dealerships.
Simply a warning that folks may sure want to investigate needed repairs. Taking
the time to understand exactly what is going on before having the vehicle repaired
may save them a great deal of money.
