I think someone needs to start a sticky on this issue considering both the amount of threads and misinformation out there.

I had this intense squealing problem after swapping to DBA 4000 rotors and Endless pads. In trying to retify the problem, I've been to three workshops, swapped in and out five sets of pads (including Ferodo and Bendix Ultimate, Advance and Heavy Duty) had the rotors machined twice and on and off the car countless times, even tried the above combinations with standard rotors. I had the calipers rebuilt at considerable expense, tried a variety of shims, goos and compounds trying to get them to shut up.

Currently, I'm back to standard pads with the DBA 4000s with custom shims, and the squeal is still there on occassion but bearable. My pedal feel, and general braking power, however, is poor.

I reckon its just part of the parcel. If you want uprated/upgraded brake pads, be prepared to get some noise. some will squeal more or less than others, but it comes down to the compound of the brake pad, and regardless of what you do it will squeal to some extent.

dude, do not put silicone, or sellys gap filler, or plaster of paris on the back of your pads. none of it will help and all of it will destroy your pedal feel.

you need to use either the marketed brake anti-squel grease, or high temp copper grease. put some on the back of the pad, place on one shim, put on a little more, then the vented shim, then some more, then the angled shim. do not use too much as you don't want it getting on the pads friction surface or on the disk.

hahahaha yeah I figured that. I haven't got anything on there now except for the shims. I'm not concerned about it any more so it doesn't matter ;)

I think u should quit with the "Pads squeal".

If everything has been installed correctly, and has been done according to how it should be then pads wont squeal.

FYI, nissan include copper grease a part of the shim kit. I used it and have never had any squeal or noise from the rb74's i have in their now. These are a slightly more expensive pad than bendix crap too, and i only use em on the street.

Ive had my callipers rebuilt, the new rotors machined, new pads installed, new shim kit and everything is quiet. Do a have arse job and just slap in new pads, then dont do the "bedding in" period (Yes this means matching the surface of the pad to the rotor, or removing any compound from the pads manufacture) and u will have problems.

Hmmm

Tell that to oblivo.

As I said "some will squeal more or less than others" or some may not at all.

Like you have pointed out, it could be a combination of things. But it still doesn't mean that even if you do all the appropriate measures to prevent it, it's not going to stop it completely in all cases. Quote from Bendix for the Ultimates: "Low noise and quiet operation." They never said it was ever going to be a silent pad. Some people have problems with noise with them, some people don't.

as i said, if brake pads are installed and run in properly they WONT <----read WONT- sqeal.

It can stop completely.

I dont quote manufacturers, i just install pads -bendix, etc. u name it- properly and it has never failed.

LOL rightio ;) My arguement still stands. What about pad compound? That's got heaps to do with it too. So your saying if I ran a set of dedicated race pads, if I bed them in, I'm guarunteed to not get squeal even for street use & light braking?

I've had 3 sets (or is it 4 now???), and when installed properly they don’t squeal.... EVER!

Unless I do ALL of the following, they will squeal.

- Once old pads are removed, spray the pistons on the callipers with some degreaser, and wipe the pistons down well

- clean the anti-squeal shims with some degreaser and steel wool, until all goo and brake dust has been removed (NOTE: doesn't have to be degreaser, anything that gets that shit off is fine)

- spray some anti squeal brake glue on the shims EXCEPT on the sides where the shims rub together. So, on the side of the shim that will touch the piston, and on the side of the shim that will touch the back of the brake pad.. (NOTE: I don’t know if this is the right way to do it, but it works for me)

- spray some anti squeal brake glue on the back of the brake pad

Put brakes back in.

- go for a drive down the street, and do about 5 to 8 HARD stops from 60 km/h down to 10 km/h (without skidding, invoking ABS, or coming to a complete stop)

- finished.

This works for me every time.

Also, just to note:

- once I put the anti squeal glue on every surface of the shims, and it still squealed

- another time I didn't put any, and it squealed

- another time, I cleaned the shims, didn’t put glue, and it didn't squeal?

So, my directions above may not be the only solution, but it's the only solution that has generated no squeal for myself consistently.

thats a pointless argument

Yes thats fair enough. I was just using it for examples sake. Brake pad compounds differ from pad to pad. From what Bl4cK32 is saying that it dosent matter pads you use, proper installation of them will ensure in no squeal. ;)

No i said depending on what u do with your pad if u install and run em in right then no pad will squeal.

I dont know where u went off at right angles....

Ok here we go. In my other post I did refer to running in/bedding in as part of it.

Please see here....

And this here is a continuation of my arguement. I did not feel it was necessary to include all information twice.

Yes thats fair enough. I was just using it for examples sake. Brake pad compounds differ from pad to pad. From what Bl4cK32 is saying that it dosent matter pads you use, proper installation (insert bedding in comment here) of them will ensure in no squeal. :D

I'm saying it again.

It still doesn't mean that even if you do all the appropriate measures to prevent it, it's not going to stop it completely in all cases. Some people will have problems with noise, some people don't.

To say that "depending on what u do with your pad if u install and run em in right then no pad will squeal" is not true. Yes it will help and can stop or minimize squeal, but it will not always work in all cases. In a perfect world maybe, but not here :D

I'm not trying to prove you wrong, I'm just trying to say that proper installation and bedding in procedures will not cure all squealing problems.

Cheers ;)

In your case, u can live with sqealing brakes. In my world, no one has to live with a shitty job done wrong.

this is one of the dumbest things ive read all day!!!i am a mechanic and i work at a reputable business in melbourne and if i fitted pads in a customers car and they sqeeled they complain.street pads wont sqeel unless theyre in wrong.instead of fitting your pads at home dont be so tight and get it done at a MECHANICS!!!!!then this wont happen..also some race pads sqeel but im talking about REAL race pads for track only.and thats usually only using cross drilled(crap)rotors.

In your case, u can live with sqealing brakes. In my world, no one has to live with a shitty job done wrong.

It is a very common problem that is not always simply fixed.

Sorry for any inconvenience or offense I may have caused you.

Cheers & peace brother.

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
