Help: Brake issue PMu F906 HC+
I'm wondering if anyone knows why I'm getting this issue with my Pmu HC+ (F906 P-Mu's not pmao-u's hd kais)
Had them fitted by AllStar to my front brembos on my STi and there is an annoying squeak while driving/rolling. I know it's normal for these pads to be noisy when braking, I'm ok with that, but they go squeak squeak squeak when rolling at say 40km/hr or when I start rolling from a complete stop until I get to speed. Also the squeak seems to be more pronounced when in a turn with gravity forces on them, probably more pronounced in a right hander for some reason. (Sometimes they squeak at like 70km/hr too) It's not the wheel bearings, been checked by Stechnic/ASG, it's definitely the brakes. Had the rotors machined on Friday at STechnic, and the pads bedded in again, didn't help. When I first start cold they don't squeak, but after a 4-5 times braking they start to squeal when driving/rolling as described above. Is it just how the PMu HC+s are? or is there something else. I can recreate the squeals at any speed if I very slightly left foot press on the brake pedal while driving and it will squeak squeak... would a fluid flush help or be useless? Looking for responses from people who have used/are using Pmus and not pmaos, I've used those too in the past and know how those are, thanks. If its just the way these are then I will switch to some other pads for street and switch to pmus for track days only...I'll leave them on for a few more months see if it stops as the pads wear more, they've been on the car for about 3 months now, this didn't happen in the first 2-3 weeks with the new pads but then suddenly started.

It's the pads, I have used them, they squeak. Pretty sure if the rotors are machined, bedded in and checked out surely you didn't need to write the essay...
It's the pads

Cheers for confirming it...thought someone might have had a trick to stop the squeakies, but looks like I'll just have to use other pads for road then switch to those for events.

Spektre...you think B-Specs would be fine for everyday and some hills type cruising? any recommendations on daily pads that can hold their own on a tuning day/light track
cheers

Mate HC+ are meant to be Street and Track pads...too squeaky though, time to get into the habit of switching pads

Travis - it squeaks so loud at times, my stereo masks it fine inside the car...but I need a bigger stereo so bystanders hear the music instead of the squeaks hahaha and also fit in with the doof doof wrx driver stereotype lol
Worse part is going through somewhere like Leederville or Vic Park where the limit is 40km/hr, squeaking is at its peak and the sound of your exhaust can't cover it as you can't accelerate hahaha...I've scared a few with the squeaks haha
