Loud Metallic Noise

[Swindog]

So you only hear the noise when you hit the brake pedal? Like you tap the pedal and it thuds?

You sure its not just your pads shifting in the caliper when they grab the disc? Mine do it on the 4 pots as the holes are slight larger or elongated compared to the pin and have stretched the pad spring. Everytime you hit the brake pedal you get a thud or loud click from the front brakes. Nothing to worry IF its that.

Not quite tap, Like I can press it softly and not hear anything, but then that doesn't slow my car down much. If I press it down with normal pressure I get the thud thud thud, it sounds really nasty. How do i check for that? The pads seem to be fitting very snugly and there's no play in them

[Swindog]

I dont think its something you can check besides seeing if the pads slide back and forth. Is the noise when you come on and off the peddle or you press the peddle and its a constant thud thud? Almost need a video of it.

Pull the discs off again and have a good check for any damage.

Only when you press the pedal and its a constant thud

I have brah, even showed it to the mechanics and they think it looks fine as well

[Swindog]

Checked all your CVs? All your bushes? Engine mounts?

I think you need to put a video up or take it to Ichi Ban.

[Guest Bjcnz]

Yeah I might try and get a video of it today and post it, that'd probably help actually. Wouldn't mind getting someone else to drive it so I can listen outside. Cheers guys!

[Guest Bjcnz]

Finally got around to welding a nut on my old one and pulled the wheels and brakes off. Everythings perfect, there's nothing wrong with the brakes so I'm lost as to what it could be. Going to put it up on a lifter on monday so I can stand under it and have a listen

[Guest]

what about loose wheel bearings or worn hub or abs :-\

[Guest Bjcnz]

Tried the ABS, unplugged it and went for a drive, still made the same noise. Hub looks alright, dunno about the wheel bearing, but it just seems strange that it would occur as soon as I've changed my brakes, but maybe its just a coincidence

[Guest Bjcnz]

Aaahh. Come to the conclusion that Pit Stop F*cked up the machining of the disks! Got a new pair to try out on my car to see if that solves it, and if it does, yuss, though I dont think i'll be seeing any money from pitstop

[dubbedup]

do they actually do the machining or send it away?

[Guest Bjcnz]

Yeah they actually did it. I didn't bring them to them, I brought them to Evolution Motors (They let me use all their gear and watch over me so I dont **** things up lol) and they sent them off to pit stop. Apparently its quite common on Subaru disks for that to happen because the hub part is thin? Though I'm not sure. Got a pair of new ones to try out on my car tomorrow to see if it fixes it or not

[Guest Bjcnz]

Sorted!!!! Put the new disks on today and its all gone! Though found something interesting on them

Looks like they were possibly re centered? thoughts?

[Guest boostin]

Looks normal to me.... ???

[Guest Bjcnz]

Pictures are really bad quality. But they look like they've been re-centered I think? You can see circular marks where its possible they were welded up and machined? That it seems ****ed up to me cause it would probably be cheaper to buy new disks than do all that.

So its either that, or the machining of the disks was wrong

[Guest keltik]

Theyre normal so far as i can see. No welding marks or clean steel so they havnt been touched. Maybe just a small ridge somewhere on the surface we cant see in the pic.

[Guest boostcut]

the centred thing you talk about is the concentric ring that is fitted when the wheel doesnt sit on the hub, dont worry about it. they havent been modifyed

[Guest Bjcnz]

Naaa there's no ridges you can see on the actual disks (its both of them, I thought it was just the drivers side, but when I had someone else drive it you could hear it form both, and if you braked around a corner you could get them out of sink). So i'm guessing when pitstop machined them they weren't bolted on completely flat so they look fine, but they're slightly off. Apparently it happens a lot with subaru disks?

[Guest boostin]

No its not. I couldn't count how many I've machined and I've never had anything like that.

[Guest Bjcnz]

No its not?

[Guest boostin]

Sorry, no it doesn't. Didn't read your last sentence correctly. ;D

[Guest boostcut]

subaru discs arnt any different to any other set up.. i love it when people come out with the old "apparently its common for subarus" line. its because there is so many of the bloody things that it seems common

[Guest Bjcnz]

Hey I'm just saying what I was told. peace
