[B]Wilwood (F/R):
Caliper (F/R): Wilwood 6/4 pot f/r brake upgrade for 86. [B]Rotor Size (F/R - IE OEM or specify): 330mm front and rear [B]Compound (F/R): BP20 #pad 7416 for reorder [B]Tires: Bridgestone Potenza RE002 (235/40R18) [B]Feedback: fantastic from cold, survives repeated abuse and high speed stops from 250kph, no fade. overheated the front tyres on twisty mountain downhill section and still no brake fade. Scores: Dusting (1=high-10=low): 3 (and its a bad red color dust) Cold bite (1=low-10=high): 6 Hot bite (1=low-10=high): 7 Modulation (1=low-10=high): 8 Noise (1=extremely loud-10=quiet): 2 - honks like that *i have race brakes* noise Pad Lifespan (1=short-10=long): not sure yet. Does the brake dust with this combination damage the wheels/paint if not cleaned immediately? Not that I can tell. I don't believe so Brake ducts: N |

Brake Pad Manufacturer (F/R): Hawk DTC60/ EBC Yellow Stuff
Caliper (F/R): Stock Rotor Size (F/R - IE OEM or specify): OEM Compound (F/R): Hawk DTC60/ EBC Yellow Stuff Tires: Toyo RR & Nitro NT01 Feedback: I was cooking the front brakes (smoking pads, scored rotors) until I removed the brake dust shields - after that the brakes were fine. Mine is a daily driven car with 8x2-day competitive time trial track events per year - I would estimate about 500-600 track laps per season, all run at 10/10th's! I ran this combo all spring/summer/fall and they were fine for combined daily and track use. The pads squealed a little bit but honestly nothing too bad. 3 sets of front pads, 2 sets of front rotors, 1.5 sets of rear pads and the rear rotors seem fine. I would likely have needed only 2 sets of front pads had I removed the dust shields earlier! Scores: Dusting (1=high-10=low): 7 Cold bite (1=low-10=high): 8 Hot bite (1=low-10=high): 9 Modulation (1=low-10=high): 8 Noise (1=extremely loud-10=quiet): 7 Pad Lifespan (1=short-10=long): (estimate/actual) About 3 Does the brake dust with this combination damage the wheels/paint if not cleaned immediately? No idea, I don't clean my track wheels! Brake ducts: No |

I installed Carbotech XP8 front/rear, and I can't get rid of the freight train squeal...
I try bedding them on the street, but it didn't seem possible with the OEM tires to put enough pressure without locking the wheels. I then did a track day. It was possible to bed the brake properly on track, and after that, the squealing was a lot less (seemed random, about 1 out of 4 brake press and weaker). But after 4 days of normal DD, the heavy squeal is back on each brake press whether light or hard press. What do you think would help? I was thinking of bevelling the edges of the pads. Could that help? I could also try to put more brake grease (I used Permatex silicone-ceramic extreme, but didn't put a lot because I was afraid it would drip on the rotor with the track heat). I could also remove the OEM backing plate/shim that I kept, but I was under the impression backing plates should help reduce noise, not create more. Any other solution? Those brake pads are awesome on the track, but unbearable on the street... |

I ran RE71. For comparaison, last year the OEM pads were starting to fade after 3 laps. After the track sessions the brake were almost always quiet, but the noise came back after a couple of day DD. I think I'll try making a little chamfer in the pads and put more grease, and if that doesn't work try removing the OEM shims. |

[B]Brake Pad Manufacturer (Front): Winmax
RR Racing SP BBK front, OEM rear [B]Compound (Front/Rear)" W5 [B]225 RS3 [B]Feedback: Amazing track pads but behaviour is completely different between hot and cold. Scores: Dusting (1=high-10=low): 2 Cold bite (1=low-10=high): 8 Hot bite (1=low-10=high): 9 Modulation (1=low-10=high): 8 hot, 5 cold Noise (1=extremely loud-10=quiet): 4 hot (high pitched squeal when hot) 2 cold (sound like a bus when cold) Pad Lifespan (1=short-10=long): 3 cold, 6 hot, (2 track events caused less wear than a month of mild street driving, wear very fast when cold) Does the brake dust with this combination damage the wheels/paint if not cleaned immediately? Can be cleaned but takes serious effort with a pressure washer, brush and chemicals even if just cleaning once it turns cold Brake ducts: N |

Once it gets to be both a)unbearable and b)a time when I can get to doing something about it, regreasing the back of the pads shut it back up. Snug up the fasteners, too. That vibration frequency is pretty good at backing off bolts.

I just read somewhere not to put grease between the pad and the shim, only between the shim and the caliper (I put it on both when I installed them), so I'll try that, and maybe do a little chamfer. For reference, the 3000F: https://www.permatex.com/products/lu...rts-lubricant/ But the grease was dry way before that... |

Most of the squeal is going to come from light pressure braking and low speed braking. Unsurprisingly, this makes up most daily commutes.
Porsche has a great video about what causes squeal and how they've tried to inhibit it. It's very educational. [ame]https://www.youtube.com/watch?v=fUNHb9O52WQ[/ame] ...unfortunately we don't drive Porsches. Even bedding the brakes properly into silence won't be a permanent fix for most people. It will require repeated efforts to re-apply that transfer layer that helps keep the friction high enough to "fill in the gaps" as it were between the pad and rotor surface. Stopping harder to keep the heat up in the rotors and pads to maintain this layer will make it last longer, though. There are only two "real" options in my mind. Swap pads between street and track (Carbotech pads allow this on the same rotor) or just get used to the noise. I got used to the noise, but I wouldn't exactly call my Winmax W5 severe by any means. |
