On my 2009 last year I replaced my brakes and rotors on all 4 wheels.
The reason was because every time I stepped off the brake pedal I had this slight sticky feel, like the brakes were becoming unstuck from the rotors. It annoyed me as hell.
But everything is perfect and beautiful in the world now where I don’t think of the process of braking as it should be.
So after watching tons of YouTube videos, I completed the repair without a hitch.
Just make sure you have all the parts. My oem Nissan advantage rear brakes did not come with new shims. So I had to clean the decade old ones and use those.
Without those they said it could cause noise. I also had these leftover rubber caps I never used because I didn’t know what they were for until it was too late and I just kept the old ones on. I did use some new rubber part that you use on the pins.
Getting parts on eBay or Amazon, it’s a crapshoot if you get all the replacement parts. Even though really, the old stuff can be used too. (Shims, rubber pieces etc)
Thankfully everything ended up great in my case.
All of my old brakes looked practically new, like having 1 inch and a half material or whatever, it had a lot.
So I’m not scared of wearing my new brakes. I am light on the pedals. Except when I was bedding my brakes.
Hardly noticeable is still noticeabley annoying. Just keep doing your detective work.
I put anti-seize on the correct areas, and silicone paste on the pins.
Everything torqued as best you can. The caliper seals not showing abnormalities like seen on ex-moderator imstricken videos.
It took a couple of days to change my brakes and rotors because I wanted to take my time to make sure I cleaned everything, rust etc , and do everything right.
Funny you said no pads came with hardware, then say new pads and rotors worked fine?
Maybe you should get new brake pads which is why I replaced everything because I feared I would still have a problem with sticky brakes and I wanted to avoid going back in to fix it. It still be a big pain in the butt if after everything, it was still having issues.
No offense to your predicament.
See if the heat shield in the rear is not hitting your rotors.
I just bled my brakes too, but I don’t think that has anything to do with any thunk.
Good luck, I’m no expert either, but just watch videos online because perhaps you overlooked 1 simple thing that is the cause.
Sometimes old brakes will be hard to mate with new rotors, or something to that effect. Hopefully others could chime in.
It would suck if that was all it’s been to get rid of the thunk; simply new brakes.
How’s your struts, shocks, or springs. Axle, tie-rods, or especially the infamous front lower control arms with my dealership. Didn’t think I needed those replaced.
Recently I had a thunk, but more of a major shudder, eventually I got a code of a misfire. Changed a spark plug and it disappeared. Really thought my suspension was messed up too. So if thunk gets worse.....mmmm. Also got new wheels and tires, but no rotation or an alignment yet.
Still a smooth buttery ride. But do admit I am getting more sensitive to hearing the normally whiny cvt lately especially when driving our non cvt Toyota Camry, Corolla, Cadillac SRX, and Lexus is250.
Don’t know why because I’m an old fart with old fart ears!
