Brake pad shims

[Robo]

Hi There,

I recently put new brake pads in, EBC green stuff.

occasionally when coming to a stop (from high or low speeds) they screech really really loud, ear piercing.....

I have attached a pic of my brake pads and it just doesn't look right, should the shim only cover half the pad???

Thanks for your help

Cheers

Rob

mine do that too. very loud and very anoying. i'd be interested in how you fix it.

If you take everything apart, how many peices do you have?

[Robo]

If I take everything appart, from the brake pad, there is:

-> The brake pad

-> 1st shim that attach's it self to the second shim (which clips onto the pad.

-> then the silver shim which only covers half the pad..

Is that right?

Cheers

Looks like mine, so should be ok... 3 suggestions ->

1. Shouldn't happen with new pads, but the two prongs (seen at the bottom of your picture) are wear indicators and make noise when the pad has worn down enough for them to contact the rotor. If that's the case, you need to bend them back a bit or get new pads.

2. Pull the pads/shims apart, wipe them clean of dust/grime/etc and spray on some "Anti Squeak" before re-assembly. The anti squeak needs to dry before assembly.

3. My pads/shims have ONE ONLY little clip each, that goes over the corner (top left or top right of the photo) of the whole thing. They have a little hole to match the existing holes that you see. Looks like these hold the 3 pieces of the pad from moving against each other, but are so small and flimsy that I doubt that's what they're for. As I can't see these, maybe you have to have them.

Hope this helps.

Thanks heaps for your reply MarkZ.

Unfortunately the thing is:

1) Pads are about 4 months old (heaps of pad leaft and prongs aren't touching as I bent them back)

2) I stuck all the shims together with this silicon orange goo stuff

3) Yeah I know the clips you are talking about (see attached pic) have them on as well.

Even after all that they still bloody squeek.....

Any other suggestions?

Thansk for your help

I'm fresh out of ideas. What was the orange goo stuff?

Were the disks machined as well?

This could just be a characteristic of the EBC pads.

[Robo]

Yeah the stuff was Anti-Squeal in a tube... Worked for about 2 weeks.

Hmm. Maybe I'lll have to do the good old slam the brakes on at 190 k's........ hahah

I pulled out mine to have a look and i have all of the parts listed above, when i put my new pads on they don't squeak even

without anti squeal stuff.

Have u tried machining your disc?

[Robo]

Thanks XrSiSt,

hahah

I just sent you an PM (RE:K&N)....

Yeah they were machined as well.

Cheers

i just got mine from nissan...same as the s14 200sx brakes...made a BIG difference to braking...squeaky noise is gone and more pedal feel as well...check the pics out...dunno about the R33 part numbers though...could be the same...from your pics Robo it looks like we have similar sized pads...i might be wrong though

Part # 41080-40P27 HARDWARE KIT-FRONT D - about $80

Thanks Ula32,

So that kit below was abut $80 bucks from Nissan???

And no squeaking?

may have to invest in some..

[uLa32]

yep...i never had em on mine in the first place, not one metal bit!

[400HP]

Sorry ... just to revisit this old thread..... I installed my RaceBrakes pads today into the GTR rears and I COULD NOT fit the pads in with the shims as well....

So i totally removed the shims and installed just the pads... does anyone know if there is any problem with this?

Also I just started using the brakes and theres a fair bit of sqeual... is this cos they're new ??

[Silver-Arrowz]

What compound did you get? the RB74 or Comp 9? RB74 does make a bit of noise but the Comp 9's make a heap. This is normal. You can't have a pad that does everything.

[400HP]

I got RB25's.... apparently they're similar to the 74's.... anyway I spoke to various people since yesterday and the best solution seems to be to bed the pads in, wear them down for a week or two, put the shims back in with the no squeak spray as well...

and hope for the best...

Hi Robo,

just picked up my GTS-t and have the same squeeking problem... and the car has new brake pads and the discs are fine. I was told it because of the compound in the brake pads... I'm getting softer pads put in... they'll wear quicker but if they get rid ot the sound who cares... my dad worked for a car parts place and apparently many years ago now they changed the compound they use in brake pads these days so that the pads don't wear as quickly but I guess there's downsides to it!

Getting the car on the w/e so will test out the brakes and let you know!

I have the squeal problem as well, but it only happens when the pads are cold. The squeal stops when the pads heat up, and the pads and discs are fine.

I'm convinced it is just brake dust and/or related to the harder compound (as Too quick mentioned).

[NO_RSPECT]

Okay i had the same drama (sound familiar to all the other replies) lol

I thought that it was the EBC green stuff on the front of my car.

but alas it was the EBC black stuff street kevlar its called on the right side rear that was making all the racket.

got it checked. disc machined/skimmed a second time and then refitted, tested, still squeaked. took em out checked everything in with the anti squeal. still squeaked.

took the pads out and put in Bendix standard rears or something poor and non kevlar and walla no squeak.

What the... i agree.

Apparently there isnt really enough weight in the rear of the R33 to make the rears work hard enuff or some crap like that. We apparently also share the same rears as a WRX. so there ya go. I have taken my car to Brakeswest in Myaree, they are nice guys and took time to check and test and test and test and test until the came up with some sort of solution.

who knows there is no noise now so I am happy, though i really wanted kevlar on the back. bugga

Your Brake shims have been cut.

Mine cover the whole brake pad both of them

The first shim isn't a solid shim as the middle is slotted.

The second shim is a full solid shim which has the pistion marks on it. They cover from top to bottom side to side of the brake pad.
