I changed my rear rotors, pads and calipers. But now there is a scrapping sound coming from the rear driver side (I’m a noob).
I’ve tried:
– Bending the dust shield back
– Adjusting the e-brakeAnd still there is a scrapping sound when I’m going at low speeds and coming out of a turn.
– After adjusting the e-brake, I spun the wheel and the noise was gone. Then I pulled the e-brake and put it back down and the noise came back. Could I have damaged the e-brake when taking out the old rotor
– or am I going to need to replace the bearing?
This is a 2007 scion tc

anyone have this problem or know what’s going on. I though it could be a wheel bearing but I’m running that I should have heard the noise before and I would hear it when driving at high speeds.
So this now puts me no where. I just don’t know what it could be
The noise from a bearing generally is a roaring, however noise may be observed on a turn, from the opposite direction of the turn says something is wrong as well…
I.E. if you turn left, and you hear the noise on the right side, then something is suspect because the weight of the car when you turn left is on the right side… Is that when this is occurring? Does the noise only occur when turning one direction?
Also, hard to say what might be messed up without pictures or more detail if something went wrong… Also is this car a manual or automatic… Automatics ebrakes very rarely get used…
FWIW always make ebrake adjustments at the wheel before you make any adjustment at the handle inside…
The good news is if it is a bearing, it is easily replaceable as an assembly instead of a pressed in unit (like the fronts)…
Just throwing it out…

I’d suggest finding which side is making the noise and going through that brake again – disassemble and reassemble. I had a brake screeching, passenger side rear, on my car. Took it apart, lubed and reassembled and the noise it gone. It just wanted a little attention.

It’s not really a roaring sound, more like a mental scarping which is why I thought It was the dust shield. The noise doesn’t just happen during a turn, but is definitely louder when turing. Turing either right or left.
The noise goes away when I pick up speed, but then starts when I’m go back down to 20-5 mph. Also It’s a manual car
Yes, I made an adjustment to the e-brak at the wheel but not inside. Do I need to do this? So maybe I should re-adjust the e-brake at the wheel (making sure the rotor slides out and back on easily) then adjust it inside.
Just a thought, if the e-break is the problem would I be able to smell a burning smell after driving (because I don’t). With a bad wheel bearing, does the sound go away the faster you go?

Rear driver side is where the noise is coming from.
I have reassemble it 3 times.
[quote=”TokyoDrift99″ post=133508]Is it rusty? E brake may be sticking on.[/quote]
The rotor? no the rotor is new.
I saw the vid of a bad wheel bearing and if def doesn’t should like a roar. Do you know if a bad wheel bearing will only make noise at low speeds?
It a scrapping loud noise that goes away when I go faster than 20mph
Not the rotor, the linkage. It’s a common problem in toyota trucks for the parking break to freeze the wheels solid and release with a loud pop. Completely different situation I know, but just a idea.

noob here, don’t know what linkage is….. Do you think it could be the e-brake shoe?
Anyone think it might be the e-brake shoe that i need to sand down a bit?
also, am I right to think it isn’t the bearing because the noise goes away after driving at high speeds and it more of a mental scraping than roaring.
UPDATE
After I made more adjustments and played with the rotor….the sound seems to be very prevalent after I turn (either way). Also if I hit a speed bump or pot hole I hear it.
Dumb question have you made sure you seated everything properly. Also another possiblty is the wear indicator is on wrong so you might wanna check that to. Another thing you wanna check did you torque your wheel down properly cause sometimes that can cause a rotor to warp.

Not a dumb question at all. I did make sure I seated everything properly and I even took the indicator off. Also I did tongue the wheel to spec.
To update, I’m still getting the metal scrapping noise but now It’s almost always exclusive when I’m turing or any slight right or left turns I make. Then I hear it a bit coming out of the turn and it goes away.
Maybe its the new rotor causing the problem. A lot of times this happens with new drums but the same thing can happen with rear rotors that have e brake shoes…. they are sometimes not machined right or warped from sitting, being banged around, and other reasons. If it is warped it could cause a noise. I would take the rotor back to where you got it, tell them its warped and ask them for a new one. May not be the problem but it is worth a try. Also the ebrake shoes may be warn funny causing a noise as well.
