I have this with my ordinary brakes. It's the pads on mine, they move slightly
There's 2 little metal type spring things on them and it's them that move slightly and that's why they knock under braking

keos_scooby

any think we can do bud

Robin Mullan

Yea, take them off.

i had something similar on my motor
turned out to be a loose caliper
only a little bit though but enough to move the caliper when under light braking
check them as a precaution you never know

as said - its probably the pad moving. Had this on my old my01 though the04 STI doesn't suffer

markmarkymark

It is the pad moving and certainly on the 2006 Sti model is 'normal' - I know as I had this checked out at its recent 1000 mile service...

I had this on my MY03 WRX. mainly when turning the wheel, and mine was the pad twanging against the disk.

Local thiever suggested the Prodrive brake kit With no guarantee it would solve the problem

I swapped the dsiks and pads for Tarox ones (disks on sale elsewhere on this site ), and this solved the problem.

When I put the original disks (but not the pads) back on the car, the problem didn't seem as bad, but I was only driving round for a few days before the car went.

I have had the pads removed, had the metal clips (whatever there called) bent back slightly and then re-fitted. Worked ok for about a week then they started knocking again only knock under light braking
I wonder if an upgrade of pads would cure it! The only thing is that my pads have a lot of life left in them and i'm not in a position to afford to change them.
Also, would/could this do any damage to the disks/pads and could it be dangerous under severe braking?
Maybe changing them Keos is the only answer

i had this appear only after doing the 4-pot upgrade!...

its annoying...

wouls love to get rid of that noise!

keos_scooby

top tuner boys dont know the cure for this one then????????

monkeyboy840

MY03WRX does the same with Mintex extreme fast road pads in so changing the pads probalby wont help

Ok, so maybe changing won't help but how about the possibility of it being dangerous and not just anoying?

keos_scooby

no bolts are loose

EOEUMC

iTrader: (5)

No, but if there is play in the pads, could they move too much and break or come off or break a bolt or anything?
It's just that I have 2 kids and I wouldn't put there lives in danger, I couldn't care about me!

Hi I have same noise/problem on my 05 sti.

Just tonight coming home round a slow sharp right hander I heard a knocking from the n/s wheel which upon inspection appears to be a problem with the brake pads/ retainers.

I've had a quick look with a torch and it looks like one of the pads has slid forward slightly and a metal clip of some type but can't make it out properly.
I drive up and down a very rough lane everyday which I think is to blame for something working loose maybe?

It seems as though this model may have a poor design for durability/safety?

I will have a better look tomorrow in daylight, but not sure what tools I need for these calipers, can anyone enlighten me please?

Cheers guys.

Hey all... Yea i have this after upgrading to the ds2500 pads... didnt suffer the problem on the standard pads... No it is not dangerous its actually onlu a very slight movement and is considered normal in high preformance breaking systems.

Thought this thread had died a death!

As far as I am aware, my pads/disks are standard ones, so this isn't just a problem with uprated parts The noise is so intermittent now. Sometimes it knocks and sometimes it don't, sometimes it seems so loud that I think something has hit the car and if I'm in the town, you should see the people that turn around and wonder what the noise was

Onan The Barbarian

I've had this on previous cars and found an explanation but I don't know if it's the same for the scoob

A lot of standard brake pads come with metal shims which slide in behind the pad and hold it tight in the caliper. Very often when the pads are replaced, the guy doing the fitting doesn't bother with the shims and just sticks the pads in.

It's not dangerous but it does allow the pads to 'float' on the caliper and that's the noise you can hear

A mechanic I spoke to reckons that brake pads should be fitted 'floating' but I'm not so sure

Please feel free to disagree with anything I've said here 'cos I'm no mechanic

BlitzSTI5

Hi all I've had a chance to have a quick look in daylight and I can see a little metal clip has slid forwards a little off the pad but still on it!

It seems very tight and wont move, is it just a case of tapping it back into place or do I need to remove the caliper or anything first?

I don't want to snap it by forcing it.

When I had mine done the 1st time, the wheel and brakes came off just he could bend the metal tabs back for a tighter fit But as I said before, in a bout a week they were banging again!

Sounds about right though Onan

BlitzSTI5

ok, will have it looked at tomorrow hopefully, will let you know how I get on.

You can all reduce the noise slightly by using an anti rattle pad spray on the BACK of the pads. It makes them very slightly sticky which in turn causes them to stick to the Pistons etc. This also helps the pads release and not rub so much on the discs when the brakes are released as the pistons physically pull the pad away from the discs.
