I recently did a full brake rotor/pads/shoes on my 2009 Scion tC. I also made sure to bleed out all the old junky fluid that was in the master cylinder while I was at it.
I used Centric Rotors, Centric Posi-Quiet Pads. Everything installed pretty easy. I made sure to replace all the caliper guide pins and also used AGS Sil-Glyde to lubricate all the moving parts and contact points in regards to the caliper/pads/pins/clips. Now I’m getting a very annoying, rhythmic scraping noise coming from what I believe to be the passenger side of the vehicle. Sounds like light metal scraping noise.. that speeds up when I speed up.. slows down as I slow down.. It doesn’t do it if I turn the wheel to the right, but soon as the wheel is left or straight its there.
The brake performance is great, way better then the rusted out junk that got pulled off the car… I don’t get any odd smells of burnt brakes.. and after a good drive, I’ve made sure to check all 4 wheels.. by feeling the wheel.. and the rotor carefully. none of them are scorching hot, hot yes.. but nothing that would lead me to believe I have a bad caliper.
I’ve had the front passenger side pulled apart like 3-4 different times now just checking everything… Rotor is pretty much center with the caliper bracket.. the retaining clips ain’t catching the rotor, and the dust shield was bent as far away from the rotor as I possibly could get it to bend away. I also made sure to do the same to the rear passenger dust shield. still the noise is present. so It’s not the dust shield. It doesn’t happen in reverse, but soon as I start rolling forward and get over 10mph it starts to happen.
What’s strange is the driver side is perfectly quiet.. no issues anywhere. Just this weird rhythmic rubbing/scraping noise from the passenger side.. the best way I can explain it is it sounds like pads rubbing/scuffing like a “shh shh shh” very lightly until I turn left and it gets more pronounced
