Anyone familiar with PFC 08s? So I installed a set of PFC 08s a month ago. I did not see any bed in procedure for them. I ran them fresh on the first session DE4 and they were shuddering. On session 2, they behaved better. So now I am using the car for weekend duty and the pads are screetching very loudly at slow speeds. Will it always be like that or is this just a wear-in phase?

I have been fan of EBC yellow, but did just have a problem

I was experiencing soft pedal, even when cold. The pads were pretty new, just 1 weekend on them.

Flushed the system 3 times, so I was pretty sure there was no air in the system. The pedal was still soft.

I swapped in some factory pads and the pedal was rock hard. Put the yellows back in and soft pedal. The pads while still having over 75% life left were cooked and rock hard

Per the suggestion from my mechanic, I got some Hawk DTC-60's. Put them in, rock hard pedal.

Just came back from a track weekend with my son also driving and the DTC-60's were spectacular. I'm not gonna use the EBC Yellow anymore

YMMV

Any squeal on the way home?

Naw, quite as a mouse sitting on my trailer :rolleyes:

actually they didn't squeal at all even when cold

Also the DTC-60'S hardly showed any wear at all and we ran around 100 laps (approx 270 miles)

I shopped around a bit and then went to Summit Racing as they match any price and have fast delivery The set for both axles was ~$400.

From everything I've read, it sounded like PFC 08's would be my best choice, but I thought that they didn't make those for the 2.7 986s. It turns out that they do indeed make 08s for my car, and I found them at Apex Performance for less than I could find the Pagid Oranges (my third choice) or Raybestos RT43 (my second choice). From what I've read on this and other forums, you can't go wrong with any of those choices (PFC, Pagid, or Raybestos).

I've placed my order for the 08s, so I will be reporting on my findings. Seeing as how it's February and track season doesn't start for several months here in the Pacific North West, it'll be a while before I'll have anything to report.

Thanks for everyone's input!

I know that I'm late to this party, but on my 986BS I used:
CarboTech 917 XP8 compound fronts and
CarboTech 738 XP10 rears.
I continued to track CarboTech's on my 981BS and I'm still very happy with them.

jsceash 03-23-2019 05:05 AM

I agree the Pagid Yellow and Pagid black are much better on the track. They last me about 2 times as long and don't fade. You will notice some squeal when they aren't hot

I switched to these brakes a week ago, in preparation for today's DE with PCA.

I gotta say, they're freaking AWESOME! Yes..... embarrassing on the street, what with the howl and squeal. But on the track, they're inspiring.

However:
I boiled the motul rbf600 fluid. Yeah..... I know.
Had to do a paddock bleed (thanks MaxD!). The next session I tried to brake harder, for less time. The brakes lasted, but I wasn't as smooth. I'll need to keep improving.

Ok so I have used the PFC 08s for a full season about 10 events.
Not going back to EBC Yellow. For one, wear is almost negligeable. The cold to hot performance also not a lot. Initial break bite a little less but modulation is excellent.
They cost almost twice as much but will likely last 4 times longer.
Also they are not.wearing the rotors down much.
They do squeal both hot and cold. Only drawback.

So PFC 08 it will be for.a.while...

Racer Boy 05-31-2019 08:15 PM

I haven't done any updates on this thread, but I did switch to the PFC 08s. I tried to bed them in at least a little bit on the street, and they squealed like the school bus from hell.

The first track session, they juddered terribly once they got hot, but towards the end of the session they smoothed out a bit, so I was hoping that everything would be fine. The second session, they worked great! I've run four more track sessions since then without any judder issues at all. Now they are mostly quiet on the street.

My second track day was at Pacific Raceway, which is notoriously hard on brakes. I did get some fade, but they would come right back if you took it easy for half a lap. Overall, they are much better than any of the EBCs I've run. So far I'm pleased!

PorscheTurbo04 06-04-2019 12:32 PM

Agreed. I just moved from a C4S with PFC 08s which squealed like a school bus.
On the boxster I also got the juddering on my first session, but after that they ran smooth and they aren't squealing at all hot or cold. My wife is excited, and I don't have to switch the brake pads back to stock for my wife in between track days if they stay quiet :)

You were probubly getting that judder because the was old pad compound on the rotors. Once it got burned off after a few laps and the new compound was burned on all was good

Hi Folks,

Old thread (Sorry, I know) but looking to do a touch point to get a consensus after 2 years whether Pagid Orange pads are still a good compromise for a street and track/HPDE application. Thanks!

Burg Boxster 01-21-2022 07:30 AM

The general "consensus" is compromise equals loosing on both sides of the coin - always.

Pads are so stinking simple to swap in/out on 9x6 and 9x7 platforms you should keep street pads for street and get a dedicated set of track pads like PFC for DE. Not to mention you WILL bleed your brakes before each DE and will therefore already be "in there".

Brakes are one of two things one shouldn't compromise on... ESPECIALLY for HPDE in any run group above novice.

Good luck :)

bcrdukes 01-21-2022 08:32 AM

Thanks, Burg Boxster. But I should be open and up front that i am NEW to HPDE. I went to a track day once on my factory pads and I "think "they were ok. I'm not sure if I can get away with a few track day session with stock pads or if I should get a dedicated set.

MaxD 01-21-2022 03:17 PM

If you are going to start running HPDEs regularly definitely get track pads. Pagid orange are a good track pad. I have run them on the street and they are not that noisy. That said, they are not quiet low dust street compounds.

As Burg points out it is not that hard to change pads and it is something you should learn to do. Bleeding brakes is the other thing to learn if you haven't done it. You will want to change out you brake fluid to something with a higher boiling point. ATE, Motul and SRF (what I run) all work well. Bleeding is something you will do at a minimum annually.

The oranges are a good starting point. Everyone has an opinion about what are the best pads. It largely ends up being preference. The best thing about brake pads is they wear out and if you didn't like them get new ones in a different compound or from another manufacture.

Also keep an eye on you rotors - they are consumables too. Aggressive pads with lots of metal in them wear rotors quite quickly. The pagids are relatively rotor friendly.

Agree and likewise somewhat disagree ;) ...

Bleeding/flushing is SUPER easy and one SHOULD learn how to DIY. Three main reasons why:
  1. it's probably the cheapest DE 'insurance' you can buy (and a v good habit to get into)
  2. you might need to do so AT a track some day (maybe Sat night before Sun) - wanna be scrounging pits Sat after track goes cold when everyone else is having a brewski asking for anyone who has a power bleeder and or knows what they are doing. Everyone is always willing to help which is great but......
  3. most dealers/shops charge ~2+ hrs labor (think $250-$450+) when honestly it costs ~ $30-75/liter (only one needed) for DOT 4 fluid and $75 one time for a power bleeder.

Bleeding needs done before EVERY track event (it's on most Event Inspection Forms - PCA especially). Period, end of story UNLESS using SRF or RBF. Over the years I cannot tell you how many incidents I have seen occur when afterwards a driver said "I thought I could get one more day before I had to bleed again".

Good luck :)

I always bleed the brakes before every event. Easy to do when changing to the Pagid Track Pads.

husker boxster 01-24-2022 04:48 AM

To add to or reiterate some of the sage advice already given...

It takes longer to get your 986 or 987 up on jack stands and the tires off than it takes to replace pads. It's a very easy process on these models (and 911 variants). IF you're going to be doing multiple DEs per yr, you can zip tie the wear sensors away from the pads since you'll be "in there" to monitor the wear. Unless you bring a spare set to the track, NEVER start a DE if your pads are less than 50%. You don't want to go home early b/c you've run out of pad.

As you progress up the run group ladder, you'll prob wear out OEM pads in a weekend as your driving becomes more agressive. OEMs will work (for a w/e) but they were also designed for quiet performance on the street. You'll need to find the right pad, whether it's a street / track pad up to a strictly track pad. If you go with a street / track pad, you give up a bit of bite but have lower dust and less rotor deterioration. Upper level pure track pads will give you plenty of bite (when warm) but will be dusty, noisy, and chew up your rotors. Only you can decide what works for you on the track and your wallet. Your home track may be tough on brakes or it might be easy on them - every track is different so it becomes difficult for us to recommend the perfect solution (but we'll try). Ask around the paddock what others are using and what are the pluses and minuses (there will be both). Just remember, everyone makes their own decision on cost vs performance and you need to figure out what works for you.

When replacing pads (either going street to track or back from track to street), bed the pads in. I do 20-60-20mph runs 10 times. You should smell your brakes by the end. Others will have their fav way to bed them in.

Defn learn how to bleed your brakes yourself. There are several good tools avail to allow you to do it by yourself. Buy one. Many use Motive, myself included.

MaxD 01-24-2022 07:12 AM

One point of clarification on PCA tech.

From the latest national minimum standard tech form:

Quote:

Brake Fluid*: Sufficient brake fluid; premium fluid recommended. Brake fluid must be changed at least annually __ ** Date brake fluid was last changed: ____/____/20____
Local regions may require a brake system bleed prior to all events, this is just a minimum standard.

There is absolutely nothing wrong with bleeding your brakes before every event. It also allows you to take a look at your pads (inners can wear at a different rate sometimes) and suspension as well.

Agree on the Motive bleeder - just don't stick fluid it, use it only as a pressure source.
