Brakes Sqeaking After Changing To Bendix Ultimates

[nuffsaid]

Hi all

Ive been suffering from a LOUD screeching squeal on occasion with light braking, sometimes even heavy.

I run standard rotors and Formula Ferodo pads (TS2000). It only really started when I put these pads in and guys at Midas couldnt figure out what it was. I left them as it is because my poor pedal feel was more of an issue that the squeal.

However after a track day, and trust me I didnt push that hard on the track, the screech was just as loud, but this time, almost every brake application caused it. This became very frustrating.

After researching for a while this is the process I came up with the fix the problem. Had some spare time so my mate helped me do it.

Basically:

1) removed the pads and shims

2) cleaned shims, back of pads and rotors with a spray on brake cleaner

3) cleaned the slit in the middle of the pads (they had massive dust build up in there)

4) sanded the pads down a little to remove any glazing (couldnt tell if there was any, not sure what it looks like haha)

5) chamfered pads with a file (ie. filed down the leading and trailing edge of the pad so its angled)

6) put some CRC brake squeal quite red goo in between the the shim stack and the back of pad

So its shim stack --> GOO --> back of pad, i didnt end up putting the goo in between the 2 or 3 piece shims

Straight away no sound, 2 weeks later, no sound!

Hope this helps.

Interestingly enough, i have the same pads, and i did EXACTLY as you did! Even filed the edges, used the same CRC goo, and the sound didnt stop

Im taking the pads back and getting a replacement. Might buy a new shim kit as looking at the image on the previous page i am missing one of them. *sigh*

So ill start fresh, fresh pads, fresh shims, fresh skimmed rotors, and fresh goo.. will update when i have done it. As it driving me CRAZY!

That shim kit is identical to what mine uses.

You need to goo. Use it. If your mechanic won't find another.

Fair enough... but he's never steered me wrong before, and you should HEAR what he says about mechanics that smear brake goo on the back of pads! =-o (my word!)

I might persist with it a bit longer and look into those shims. I know I have the four little corner ones, and the solid faced bits... but I don't recall seeing the vented ones. =-/

And Nissan FAST seems to confirm this. (ECR33)

A little bag of shim grease. ooer!

Nissan are not silly they use grease for a reason.

I'd just thought id share my experience now

Seeing as i had a set of Ferodo Formula TS2000's that squealed like a 12 year old getting ***** up the ass by a cat on a chalkboard, i tried re skimming the disc's, brake goo from Nam still to no avail.

So, i returned my pads to Repco (handy having a mate there) to swap for another set the same.

Just out of curiosity we checked the pads, the old squeaky ones next to the new ones, apparently the same.

The old ones were a bare pad, in green

The new ones were a black pad, with a green rubber piece over the back, where the squeak shimms would go! Interesting!

So, getting home, installing the new pads, and just re-using the squeak shields covered in CRC Squeak stop (NB i did NOT apply any more, as there was still a sufficient coating, and did NOT apply any to the pad surface itself)

Cleaned everything again with brake cleaner, re-installed everything, bed them is as per instruictuons. Let them cool off completely, and i have just been for a 5-10min drive around the city, up hills, down hills etc with variable brake force, and im happy to report that the brakes havnt uttered a peep

Hope it stays this way!

GL for everyone else. As it seems, there is no guaranteed cure. Its just trial and error, and i have found my correct method All smiles here!

hey, i was missing the shims. hence the squealing. plus, i added goo. all gone now..amen

Just thought id add that after a few hours of driving around town, the squeak came back but it is intermittent (spelling?) and is nowhere near as loud as it was, so its bearable.

Hoping it might go away with age and wear.

I was about to suggest that the noise would come back. It did after I got my car back... a few days and the rears started... then a few weeks and the fronts are going mental!
