brake pads...

Actually coasting has a different noise... just had a friend (who's a mechanic) put in a new bearing/RF rotor... and he mentioned to me whoever did my brakes last (was a while ago) put in cheap pads and now there's a noise. Funny thing is I never noticed this brake (and coasting) noise before he mentioned it to me.
It's actually my brother's g/f's brother... so it's not like he's close... so I don't want to keep bringing it back there to trouble him... so I may just leave it if it's not a huge problem.
Do cheap brake pads simply wear faster? No other drawback?
<-- wishes he was more mechanically inclined...

All I can tell you is that it took 1.5 hours of labor to do a hub bearing ($77) and R/F rotor ($25). IIRC, the brake system was "repaired" by Mavis Discount Tire almost a year ago... cause for that was vibration when braking. Don't recall what they did then... but I wouldn't expect Mavis (a big chain around here) would install cheap pads.

To be blunt about answering your question: no, cheap pads will not, in and of themselves, cause brake damage.
Poor maitenance when the pads were installed (not turning the rotors if they needed it) *might* cause problems.
Run from any mechanic who blames car problems on cheap pads. He's either ignorant or trying to scam you. In either case, you don't want to do business with him.
What kind of 'noise' are we talking about?
A sqealing noise would be common for two reasons:
1) new pads that haven't had time to 'meld' to the rotors yet
2) worn pads that are approaching the end of their life. The feeler gauge is scraping against the rotor. This is normal and is the brake's way of advertising, "I'm making an inexpensive noise now! If you don't replace your brake pads, this noise will be replaced by an expensive noise soon!"

A faint and soft scraping noise... like if you slide sneakers across cardboard softly... that's what it sounds like. Doesn't sound painful, but I'm just worried about any premature wear on... something.
I know what a brake warning squeal sounds like (sharp metal)... and it's not that. Keep in mind these brakes have been in for a year too... and have only started making noise after retrieving the car from rotor/bearing work only.
To reiterate, he warned me that there were cheap pads installed (I know that it was a year ago) and that there is a noise now.
What would bleeding the brakes do? What if it's not done?

There are, as far as I've been able to determine, two distinct differences between "cheap" pads and "expensive" pads.
First, the way the pad material is mounted to the backing plate.........either glued or riveted. The more "expensive" pads are riveted, but I think it's more to do with the car manufacturer's preference.
Second, the pad material. True, cheaper pads use softer material vs. the more expensive ones, but this in itself is not any cause for alarm. True, softer pads will wear out faster than harder pads, but harder pads wear rotors faster, take more heating to become effective (which is why I chuckle at persons spending lots for carbon based pads.....carbon pads need so much heat to become effective stoppers that on the street they are a tad ineffecitve for that sudden out-of-theblue panic stop---racers use them but in racing one is on the brakes much more often vs. street use), and harder pads can squeal more than softer pads.
Cheaper pads, ie. softer pads, won't damage your rotors.
Squealing can come from several reasons........glazed pads (they became overheated and developed a glaze), worn pads, or anti-squeal prep on the pads when installed wasn't used.

One time my gf (now ex) wanted me to put pads on her car. She had gotten a set from AutoZone. They lasted 6 months. Next set of pads were from Wagner (not from AZ) and lsted more than a year (split up before they finally wore out so I have no idea really how long they lasted.)
I now lean towards using OE pads on cars and trucks. It has reduced the number of people who come back for noise complaints. I also make sure that the rotors are either turned or replaced (if under specs.) If the pads come with hardware, I use that and if it doesn't I get new. To many liability problems if brakes fail.
