Slider pins (these should have been cleaned/lubricated at your service), or a stuck caliper. (Caliper pistons can stick when they are retracted into the body to fit new pads)

Bring it back to the shop,
good for you noticing that one rotor was rusty!

Thanks for the input, i was thinking the same but i am fearing the replacement costs of calipers. Just a shame that they gave the pins and calipers the all clear at replacement time. Hopefully they will not charge another brake pad replacement fee...i am overly anal about my vehicles now days, too many wheels have walked away from me, while driving, when I was younger 😜. Plus i know rust can be normal but when one is different than the others, there is an issue somewhere.

 

Rebuilt calipers are reasonable in the USA ($40 - $100 ea in the USA on Rock Auto). In some localities they just rebuild the existing calipers (remove rust from piston bores, new gaskets/seals)

Best to do this repair in axle sets to maintain proper braking.

Since you noticed the issue in time, you prob didn't do anything bad to the pads...(It is the opposite side that needs to be inspected as that one has been doing ALL the work)

 

Do you know what brand/model pads were used? I have a feeling you didn't get decent quality pads put on, hence the noise. I have seen Honda calipers stick, but not really make noise (I'm not saying that they don't make noise). Maybe the pads aren't the right cutout that the calipers prefer, and they are making noise.
Try another set of pads, get a different installer to put it in. And use silicone lube on the pins not regular grease as regular grease will kill the rubber sleeves on the pins themselves

They used champion brake pads and rotors ( i asked for decent quality, i don't need anything fancy) they rechecked the brakes and upon inspection of the rotor runout found that the LF rotor was machined/created wrong as only half the pad was touching the rotor. Essentially half the rotor was lower than the rest. The shop said they have not really seen this outside of the low quality parts but are not surprised these days as manufacturing costs have been cut. The manufacturer gave new parts and i got a full new brake job. The slider pins and calipers were good. Basically the noise was coming from a thick buildup of rust contacting the pads.

 

Did they lube the backs of the pads?
That's a must to prevent squealing.

 

I bring back to who worked on them day one not weeks later, but since its weeks later the rust will not get removed because the pads do not get to the outmost edge

get the rotors changed. you may watch my old vids , to see how simple/hard it is.

oh one last note, my thoughts out loud

 

Yes, the garage changed the pads and rotors today. I waited so long because there has been a lot of salt and rain lately (benefit of the doubt), the garage is an hour away (i trust no one 😁) and there seemed to be no immediate danger. It

 

Update #2
After 4 days of no issues, the noise returned and the same issue has occured with one of the rotors. I assume there is a bad batch of rotors floating around now. I'll take the car back again and see if theyll upgrade the parts this time.
