Just needed some advice from you guys. There's a scraping noise coming from the rear of my civic when the car is in motion. It sounds like metal to metal scraping. I haven't really checked my rear brakes in a long time.

I'm going to take off the rear wheels this week and diagnose the problem (as soon as the weather gets better). But until then, give me some suggestions on what the problem could be, from simple to worst case scenario.

hmm scraping noise..well if ur car is lowered but that wouldnt be metal to metal...i think your brake caliper pistons are not functioning properly..take them off..grease them and change the rubber pieces..if they r in really bad condition replace them too

Thanks Alekss. I was thinking along those lines. You think it could be that the pads are gone? I'll be able to confirm all this when it gets sunny outside (I don't have a garage to work in).

correct me if i am wrong, but your car does not have disk brakes in the back, hence no calipers or pads... it could be your break shoes that are worn and rubbig your drum

Sorry, just to clear things up. I've done a 01 GSR rear disk conversion on the car.

could be warped rotors (which is likely the case)
or if you installed those stupid metal deflectors on the hub assembly then it might be touching the rotor

probably pads wore down to wear indicators... expessially if the noise goes away when braking

Anything besides rotors/pads/caliper that could also be the culprit?

PunkInDrupblic: The noise goes away only when at a complete stop. The frequency of the noise increases or decreases upon acceleration or deceleration.

Looks like it'll be an ok day tomorrow, so I'll jack up the rear end and check the rotors.

DS rear rotor, when I looked through the openings on the steelies, seem to scuffed.

BTW: What's the minimum brakepad width that one can get away with?

adjust e brake cable?

What size of rims do you have on the car.

I have 14" steelies on the car.

It started to drizzle yesterday, so I got lazy and didn't check it. Tomorrow is supposed to be nice, so I'll pull the wheels off then.

Crud rust and metal bits in brake drum???

That's my guess.

Last brake service?

Well, I finally looked at the discs in the rear, the rotors seemed to be warped. The brake pads are still thick though. Another note would be that when I turn the rotors, it turns pretty easily ( the handbrake is down at this point), until one part of the rotor reaches the brakepad/caliper area. It becomes difficult (still doable) to turn for maybe two inches of rotation.

Suggestions? And what I mean by warped is that when you feel with your finger (when moving towards the centre of the rotor) it's somewhat smooth and then a noticeable dip on the rotor itself. Basically: centre ___/----- (crude I know)

Calipers?
