Hey guys,

I've recently replaced the rear brake pads on my car, and it developed some kind of knocking noise when I brake just moderately hard.

I took the car back to the technician who did the work and he checked to make sure it's not caused by a nail in the tires. He didn't notice any issues, so he just took the pads off and put them back on. The problem went away for a couple days but now it's back again.

I don't feel too confident about taking the car back to the shop that did the job; they couldn't figure out what the issue was the first time, so I don't expect them to fix it.

If anyone had similar issues, or know what could possibly caused the problem, please let me know!

Thanks!

does the noise sound like this:

i believe it is your pads, so just ask the place you bought the pads from to exchange them (use a different type)

or if you are too lazy/not able to find a receipt, just take a car for 15 min drive at 60-100km/hr, brake occasionally, and the sound may disappear shortly, but may come back later

I'm guessing, just guessing that your rotors were slightly warped and should have been
turned before installing new pads.

I would never put new pads or new rotors on by themselves. I always either get a
new set of both, or at least have the rotors turned true when putting on new pads.

my dad's a machinist and turns rotors at his shop for like $5 or $10 each, it's worth it.
