You think the stock FD rotors are of better quality that Brembos? On Maxcooper's website he said he got brembo fronts for $60/each.

Ready to buy my extra set of Blues?
Rebuilding calipers is easy and a kit costs about $35 from mazdaformance.com. Might be smart to do it just in case. (Since you have done *everything* else. I would help out, but I don't have the time.)
If you do end up rebuilding, pick me up a rebuild kit too, I'll give you $$ for it when you pick up the impact screwdriver. Seems like a good idea to have a spare kit in the garage, just in case...

I had this problem with two of my cars.. except the 7.. but my experience with it and one way to find out is to see if your pistons are locking is to see if one wheel is hotter than other.. In this case, I think its both sides??
I After normal driving on the road, your wheels should feel warm.. not HOT.. if its hot then your piston is pushin the pad constantly and not retracting.. I ended up re-building my calipers myself.. usually as it ages, build up occurs.. I just pushed the pistons out and clean the inside with 600 sand paper.. gently removing build up and polishing the piston.. Now, it works fine..
Hope this is the problem.. Good luck!

hey phil, dunno if you read furhter up but already ruled out piston sticking cuz i ran track saturday with hawk hps pads and it wore even.... i think the stock pads just blew up, that was the deal...however i did move the pistons in/out before puttin the hawks in so it may have unsiezed a stuck piston... they all moved fine when i was putting the hawks in

Glad to hear the HPS did it for you.

Hawks vs Greens

They work when cold, and appear easier on Rotors too..
And just get better and better as they get hammered...
I love them

i forgot i own an FD
project mu bforce
I was changing out my wheels, so I thought I'd check my project mu bforce pads to see how they held up after the north course at VIR and a couple months of street driving. They don't dust much at all and I still got 1cm left. btw, they performed great at the track.
Here are a couple pics...

Racecar - Formula 2000
I drive an FC racecar in SCCA Nationals. I also own a '93 FD3. With both cars, I get pad wear similar to this.
The uneven wear is due to the drag of the rotor on the pad during hard braking. The pad backing plate is not on the same plane as the pad surface. This offset causes the pad to be torqued toward the leading edge, causing the uneven wear. The higher the pad coefficient of friction, the more this tends to occur.
One solution is the previously-mentioned calipers with different sized or offset pistons. Another somewhat effective cheap fix is to grind, machine, or cut off the pad material at the pad trailing edge. How much you have to cut off to even up the wear is a matter of trial and error.

Dave, what does your FC look like and what class do you run in? I attended the event in San Diego. Don't tell me you own one of those 500hp demon FC's! I think I remember an FC putting down the fastest time of the day aside from those little 125cc karts (damn those things are fast!)

Racecar - Formula 2000
Chronos, actually, my "FC" is a "Citation 95SF" formula car - looks a bit like a Champ Car, but costs a lot less. It has a Ford 2-L motor (restricted) and wings. It was built by Indianapolis Competition Products in Indianapolis, IN.
It races in the "Formula Continental" class (FC), one of 24 SCCA National classes.
I've been racing SCCA Nationals and the Valvoline Runoffs for 35 years.

Your pads are looks exactly like mine after use on the track. Extreme uneven wear and pad material breaking apart in chunks. The uneven wear was caused by a stuck piston, and the pad material breaking apart was form overheating. A rebuild of the front rotors solved the piston problem. Cost was in the order of $20 a few years ago. I now use Hawk Blues on the track and work great at high temps.

EBC Greens are great for cold bite and High Temp Range (work COLD and HOT) but they WEAR OUT FAST they last abt 1/3 as long as Hawk HPS or HP+ and cost more. a NEW Greens were 85% gone in less than 2 hrs (4- 25 min sessions) at the track (Streets of Willow Springs) on my fd.

wow, that's definately something to consider...anyone have anything to say about the Endless CCX? They truly do seem to be the best pad I've come across for street/track.

Please note I have Type RS/RZ calipers and rotors. The larger rotors dissipate heat more efficiently than the US spec brake rotors.

My experience w/ ebc's are limited to that one event (I went back to HPS/HP+ after that) back in NOV 01, maybe ebc has changed compounds since then? also my fd is a touring automatic w/out any thing removed so I am running at a full 2900+lbs.
