Not true. The parking brake uses exactly the same pads that the

all four.

Maybe on YOUR car, but not on my Mercedes.

You make the mistake of generalizing on the basis of a too-small
sample -- in this case, a sample of one.

The parking brake pads are
completely seperate. I'm not sure what various other manufacturers
do. I'm sure others as you say do use the same pads.

Trust Mercedes to do something bizarre. Your car is the exception, I
assure you. *Every* vehicle I have ever owned used a cable to activate
the same pair of rear shoes or pads that were activated hydraulically
by the service brake. That list of vehicles includes three Dodges, a
Plymouth, a Ford van, a Fiat, a Chevy truck, a Dodge truck, two
Mazdas, an Oldsmobile, two Buicks, two Suburbans, two Saturns, and a
Pontiac. _Every_single_one_ used exactly the same pads or shoes for
the parking brake as for the service brake.

some cars with rear disc brakes use a tiny DRUM brake built into the rotor
center for the "emergency" brake,because disc calipers need so much more
force to be effective.

either way,cable brake force is NOWHERE near the braking power that
hydraulic discs have.
