HELP - fitting new brake pads - need advice

[Cuppa]

I'm fitting new EBC greenstuff brake pads. Their fitting instructions are woeful, & with no diagrams. Obviously they assume knowledge I don't have.

Issues is anti squeal shims. OE ones are metal.

The EBC pads are supplied with a sticky backed rubbery sort of shim.

Do I stick it to the back of the pad or to the shim cover? (Replacing the metal shim?)


Would really appreciate quick replies!

Thanks

I would say back of the pad if it is the same shape there cuppa that's where the antisqeal shims are supposed to be from memory

Would you mind posting a pic of the pad and the shim side by side

[Cuppa]

Here's a pic.
From left to right

New pad, rubber shim (with 3M peel off sticky back), original shim, shim cover.

My gut feeling is that the rubber shim should be stuck to the shim cover, with the black face you can see facing the pad. No anti squeal grease is supplied, only grease for the siding pins. I also am assuming that the original shim is not refitted.

Don't want to fit it up wrong.

we used to just squeeze a bit of never seize to stop squeeling which is chattering really
I'd put rubber pad on rear of new pad,
they don't know what pads you are replacing

[Cuppa]

I'm concerned that the back of the pad may get hotter than the shim cover & more likely to make the adhesive 'let go'???

[Cuppa]

Found the answer ....... You were both correct - stick on to the back of the pad.

Sorry I took so long cuppa I am looking after my daughter today and when we start playing time flies by. Glad you found the answer though

All back together now want your opinion when they are bed in,
It may be more noticeable with your Patrol being Heavier.
It has to be better than before though

[Cuppa]

All back together now

Hmmmm, not quite!
I think I could now declare myself an expert at dismantling & rebuilding manual locking hubs having done so another 4 times today. After doing them each once I stood back to admire my handiwork, only to realise that I had stuffed up. I knew the new rotors were a directional fit, but despite this had somehow managed to fit them the wrong way round, with the passenger side rotor on the driver side & vice versa. Bugger! All done now, just one set of pads left to swap.

Easy mistake to make when you are excited about the benefits of new bits

Just back from 60kms bedding in the new pads & rotors.
Good news & bad news.
The good is that, like you, initial impression is of a huge improvement in braking, both in stopping power & feel. (The latter a pleasant surprise).
The bad is they squeal. Grrr. I did the initial bedding in as per the instructions over about 30kms & no squeal. At about 35kms I braked a little harder (but still reasonably light) slowing from 80kph to 60kph & had the first squeal. Now they squeal every time I brake. I’m hoping that the squeal might disappear with a couple of hundred more bedding in kilometres, if not I suppose I’ll have to pull the pads out to see if I can do anything.

[threedogs]

I always thought the squeal is caused by vibration , thus the graphite paste on and pins and back of pads
Maybe a few panic stops will cure it. At least you don't need to pull the whole lot apart again,
would the old backing plate fit in behind the new pads??

Lips are seal about direction ,lol

[Cuppa]

I didn’t use any goo/paste on the back of the pads, it didn’t seem like the right thing to do with he stick on rubberised shims, but I may try it if the squealing persists. Plenty online to suggest that squealing can disappear once the pads/discs are fully bedded in.
I did fit the old metal shim cover over the rubber shim. Not sure if this was right or not. The installation instructions with the pads really were very poor.

[threedogs]

Dumb question but did you thoroughly clean and dry the Rotors with Prepsol or similar ?

I followed the instructions & cleaned them with warm soapy water. I then gave them a good wipe over with methylated spirits just to be sure.

Seems strange that they squeal, will admit mine did but not enough to warrant a comment.
Only 3-4 times if that. I'd do a few panic stops somewhere safe of course, as long as you
don't get them super hot in these early stages I cant see a problem

EDIT Green are just H/D towing style pads Yes, not racing pads like a Kevlar job

As for getting direction right I fitted the rear first when some one commented they were on the wrong way,
I said LOL they are just so I can see which way they need to be, yes direction was wrong but picked up
and corrected before assembling

From a web site.

EBC green stuff pads are the only pads made with KEVLAR (r) fibers. The EBC green stuff brake compound uses no carbon, so there is minimal dust. The friction coefficent of the EBC compound is 30-40% higher than common pads, yet rotor wear is minimal. Suitable for use on the street or light track use -- stable braking characteristics up to 550 degrees C.

They come with a 'braking in' coating on their face.

[93patrol]

Or maybe you didn't get them hot enough and they put a coating on the pad.

[threedogs]

That's what I'm thinking and why you may need some aggressive stops in a safe spot ,
but not aggressive enough to get rotors glowing, BTW do they smell??

[BigRAWesty]

As above. Get up to 60 k and stand On em.. Get the abs working. Make sure you have no breakables onboard..

Do it 3-4 times. I've found that they do squeal if you use em lightly a lot to. Again, if this happens brake harder for a bit.

[threedogs]

Its a 4.2 ute so not sure if it has ABS, but I'm all for some serious braking efforts,
Maybe they need to be hot to work like green pads in racing circles

[Cuppa]

Yep, no ABS.

The bedding in instructions which came with the new rotors says to avoid heavy braking & getting them too hot for the first few hundred kilometres. Ebc's bedding in instructions (http://www.ebcgreenstuff.com/EBC%20Bed%20In%20Procedure.html) say much the same. For now I will put up with the squealing & hope it goes away.

[threedogs]

Yeah I'm sure they are bedded in to the letter, get the Ks up on them so when you want them to work they will.
Used mine in anger the other day , boy do they stop, so get your 1000Ks up and report back

[Cuppa]

Went out for another bedding in drive today, & have found that the squealing is already reducing. Still does it, but not so loud & most noticeable on very light braking. I’m optimistic.

Heading in the right direction .... :)

I am sure that they will complete their bedding in procedure and stop squealing soon
