For starters, my 2010 Altima has a brake "anomaly".
But before I get into the ugly details ... How do the pads/calipers on a disc brake system retract after use?
On drum brakes, there are return springs which pull the shoes back when you release pedal pressure.
But on a disc brake, there are no return springs. Seems the pad would continue lightly touching the rotor after the pedal is released, which would cause friction (and heat) on the rotor. (right?)
Inquiring minds want to know!
Thanks.
