[RESOLVED] Installed New Pads and Rotors on 2G Awd. NEED HELP!!!

[jm1080]

So my buddy just installed some new pads and rotors on my car and everything was installed properly because he has changed brakes before but never on an awd car. He compressed both pistons at the same time with the C Clamp and using old brake pads. The car now makes a thumpong noise while driving (coming from both wheels) and it seems like the pads are always rubbing on the rotors. What could be the problem??

Make sure that the pad backing plates are on the pads and that the retaining clips are installed correctly. I had a similar problem once when the clips were not installed correctly.

bleed the system

We removed the pads again and checked the calipers to see if they were frozen. We removed them from the caliper brackets and pressed the brake pedal and both pistons on each side worked so we reinstalled them again making sure that everything was installed properly. The brakes do work fine but there is this sound that is kinda like a screaching sound but with a bass tone to it. We think it might be wheel bearings because th sound went away after a while at higher speeds but came back again but mainly at lower speeds. Very strange man...any ideas?

1 of the new rotors is bad . . . I have had this before -

C-clamp on front calipers, but not the rear. The rears screw into the caliper. You use the tips of a pair of pliers and screw them in. It's due to the self adjusting parking brake built into the rear calipers. Maybe you didn't hurt them and TALONTRAX is right about the bum rotor, but just so you know. Also, if you don't torque the wheel lugs evenly, you can warp the rotor in a hurry. Always use a torque wrench on you lugs, and tighten in two or three steps.

Well so far we only installed the front two rotors with pads not the rears yet. So far we believe it is the wheel bearing or axle because we have already ruled out the brakes. It only does the noise when making hard right or left turns and there is a bit of play when moving wheel left and right.

Ill try and get a video of the noise tomorrow for a better diagnosis. It is night out so we just gave up. Tomorrow we will jack it up again and try to figure it out more money damnit!

If the problem wasn't there before, it's probably related to something you did. I'd check for a piece of crud in between the rotor and the hub before I yanked the hub and pressed out the wheel bearing. Seriously, make sure you don't have a bum rotor before you spend more money/yank the whole hub.
Plus, the wheel bearing makes a low-pitched rumble, not a high pitched whine.

Maybe you could leave the caliper off or strap it back somehow. could be sticking and draging on the rotor mite save time and money. if it does it with out front caliper's than move on to your wheel bearing

i had that same thing hapen to me om my 2g awd.it was the tie rod, that would explane the play in the steering wheel , but as for the noise when you turn it can be a bad rotor or the wheel bearing.

is it a clank or a kinda grinding noise?, low pitched grinding noise is a wheel bearing.
we'll wait for the the video clip.

2g's have a drum in the rotor hat for the parking brake. The rear calipers have a normal piston, just like the fronts.

before you put the wheel back on, tighten down the rotor, spin the rotor, can you see where it is being interfered on with the caliper/pads? that might help you find your problem.. it might be the rotor or the hub. rotor might be fine, but the hub is not, and it wasn't doing it with your old rotors because after a while might have scraped down in time of use..

I appreciate the help guys! We took it to a dsm expert heh and we found the problem this time. It is the front axles. It makes like a knocking type noise as if they were hitting each other, wobbling loose if you know what I mean.

I was going to take video but forgot but as we already diagnosed the problem. I dont believe it necessary. It keeps getting louder that people are like WTF

Ill keep this thread updated once we change the axles to see if that was indeed the problem

He tried to tell me I didn't know how to install new pads and rotors. j/k Now lemme pop in those new CV's....ha
