Default s60R R brake upgrade=massive brake squeal. Thoughts?

My 242 was upgraded to s60r brakes using STSmachining's adapters and since I have had massive brake squeal. Mostly at light to moderate braking. Under hard braking it stops. I'm not talking a little squeal here. Ear drum bleeding in stereo from both front brakes. I find myself waiting till the last minute to brake so I can brake hard to keep it quieter.

Before everyone starts throwing ideas, let my tell you what I've done.

3 completely different sets of pads. Different compounds and different brands. Made no noticeable difference.

I have chamfered the edge of all the brake pads with a grinder ...No difference.

Rotors, I originally had cross drilled and slotted. Changed them to OEM plain rotors, no noticeable difference.

I'm open to suggestion here guys. Has anyone had similar results?

Stupid question, but have you greased up everything? Brake Squeal is usually caused by a lack of lubrication. Also, the s60r actually had a campaign about brake squeal. I can't remember if they changed pads and rotors, or just pads.

Brake noise can be very tough to cure. The best first step is to use lots of lube. Even on the pad anywhere the caliper touches. Try new hardware also and make sure it's properly Iinstalled. Wire brush the brake hardware surfaces and maybe even lube under there too.

What pads? Squeel is normal with aggressive compounds.

Also, stock Brembos groan normally when driving as well.

There is a shim available for behind the pad. I believe this is the campaign mentioned above. Can try those out.

+1

The flat shim eliminates it 90% of the time.

We installed these on a customer car, works great, zero squealing. The rotors are really expensive I would recommend buying the AKEBONO pads from IPD. Get your rotors turned down give a nice clean surface.

Odd though. I am running hawk HP+ on my v70r with no shims and don't have that bad of squeel. The usual aggressive compounds whining when stopping with mild braking force.

Got a video?

Pad shims. Should come with the oem pads. Not sure if available separately. I usually just re-use the old shims.

I have those stoptech rotos on my wagon. Purely anecdotal but I've experienced no squealing with them.

Shims and lube all metal-to-metal contact with a SMALL amount of appropriate lube.

My rear pads (brembo pads + brembo 330 no drilled rotors) stopped squealing after the dyno session where wheels got 15 times up to 240 km/h ... So i assume it was the brake dust or something.

Plus LOCTITEpaste does miracles

Just installed s60r fronts on my 245. Im using stock oem rotors, akebono ceramic pads that came with shims on them and that red lube stuff that semi dries. Zero squeal or chatter. I went heavy on the lube

Grease alone won't work. Make sure you use the shims too. Really hot temps or really cold temps, I get minor squeal (even with shims) but most passengers don't even notice it.

Shims, man shims....

Same Pad is used. Makes me wonder. I'll try a true caliper piston grease instead over pistons with the semi lastic squeak product thats on there now.

Maybe it's your custom relocation brackets.

I was actually thinking that. Maybe the caliper is not centered over the rotor?

Didn't they offer a stiffening/dampening bracket for the R brakes?

Hmmm. Didn't think about that. Guess I could buy a different brand of brackets and see.

I have no update as of now. Mine are still ear bleeding squealing at anything less than full on hard braking. I'll be pulling it apart this weekend to re-check alignment and centering. I have the metal shims that came on the r calipers. Like I've mentioned, I have tried 3 different pad sets of different manufacture and grip. I have also tried plain OEM rotors and my dimpled and slotted rotor all with the same results. I'll recheck everything and assemble with lots of grease. However I won't have results for a couple weeks as I'm also swapping out heads and cam.
