Default My brakes seem to suck...

Ok I have 600 miles on the car and I am very unimpressed with the brakes. The pedal is very firm (a good thing) but the pads have no bite, do they just need more time? I am starting to think maybe the prep guy got crazy with the tire shine and oversprayed. How are your brakes? I have always changed to "good/high performance" pads on every car ive had so I am used to alot of bite as compared to a "progressive' Type pad, so maybe Im just expecting the wrong thing?

I had a similar problem at first. I did not like the pedal feel, and did not like the performance of the brakes.

But then.....

The finally bed in, and broke in, and gripped like hell. About halfway through my second track session at Watkins Glen they started biting like you would not believe. just give them time, give them a few hard brakes, and let thme do your job....you will be fine.

FWIW I have noticed that it seems as if you need to get some heat into them before they really start biting. THe brtakes on the EVO are very similar. You could always try going to a different compound pad. I'm sure it would help noticably...

Search around the brake forum for break bedding precedures. It basicl involves gradually warming the brakes up with progressively harder stops, then a few very hard stops in a row. Then drive around to let the the braks cool off.

I also noticed this. It seems when driving around 50 and you want to slow down the brakes work well at first push (Slows car down a good deal) then as you continue to push the break pedal (At a costant pressure) they began to suck and almost feels like they don't work or you have to apply a great deal more pressure to stop the car. This what you guys getting?

Might I add I only have 500 Miles on the car, it may just need some time.

mine were too grippy at first...i think i just got used to them, and everything is great now. they stop really well for me...and i was coming off a miata before. IMHO, the miatas brake feel is a 9/10 where the STi brake feel is 8/10. as far as potency, the STi wins, of course.

I agree the brakes feel odd - sometime they require little effort other times more effort is required. I only have 700 miles on my STi. I think those of us who are still breakig the car in and have few miles need to take a breather and report back after we get a few thousand miles on the odo.

Just to second what Red Rocket said about bedding in the brakes. Sounds to me like Subaru put some pretty high performance pads on that need the race pad bedding procedure as he describes. I would add a note of caution, however, to remind folks that you are also breaking in new rotors. I think in the first few hundred miles you should be very easy on the brakes, so rotors bed in along with brakes. Then I think the procedure of high speed (maybe 80mph?) with hard pull downs(to maybe 30mph) repeated 8 or 10 times in a row, followed by a complete cool down, and you should be good to go.

The Owners Manual states that the 1000 mile break-in period also applies to Brakes and Clutch.

Default Brake Efficiency

Biggest problem I have with the Brembos is that they work so well that once I have the brake pedal deep enough to heel/toe, I no longer need the gear I was planning on. I'm almost at a dead stop.

The brakes seem to require more effort at low speeds. I don't know if this is part of the EBD being smart for parking maneuvers versus at speed stops? How intelligent is the EBD supposed to be?

For brake bedding-in I believe most would recommend this type of procedure:
A hard stop from 40mph down to 5mph at the limit of the anti-lock system activating, do not come to a complete stop;
Allow the brakes to cool completely, i.e. drive around for 2-3 minutes without using them, then repeat the procedure above from 50 mph down to 5 mph;
Repeat same at 60mph, then 70 mph and lastly 80 mph.
All of the above should ONLY be done when you have 200-300 miles on the car so that the pads have 'conformed' to the rotors.
If you intend to track the car, a couple of hard stops from 110 mph to 5 mph will fully season the rotors/pads after you've done the above gradual 'stops'.
This is the advice I've received from brake experts on various other boards

Default Back to basics.............

My first instructor at my first track event 11 years ago told me at the end of my first day,.." now all you have to do is learn how to brake,.."

ALOT of people upgrade pads, lines, spend $ 65.00 a quart on AP600 fluid, 6 pistons calipers, and all this crazy stuff, but they dont understand actually how to brake !!

As I approach a slow speed corner (40 mph) and I am braking from say 155,..I press the pedal down(jamm) VERY hard,..At this point I am trying to all but lock up the brakes, and shave off as much speed as possible, once I feel the deceleration and can tell I will get this thing slowed down to the desired speed,..I start to manage the amount of pedal effort needed and feel the "torque of the brakes" and get my turn in just right. maybe carry a little more brake into the corner,...blah-blah-blah.....

I would say 95% of all my students, simply dont press that pedal hard enough,...period,..........

I took a drivers ed event with a rental car neon once and worked on my threashold braking,........trust me when the Porsche came out the shop ,I was a better braker, by far.

OK,.HERE IS MY POINT,........in the STI,..if you drive 120 mph, and jamm the brakes on, hold the same pedal effort til the last 25 ft,.you'll notice something,..the last 100 ft feel like someone dropped an anchor !!......that is NOT heat in the brakes,..it is the EBFD kicking in,..the sensors have determined that you are in a panic stop. I have been playing with this for 8 weeks,......quite simply put,........

If you brake very hard this car will stop much better, because the EBFD will distribute more pressure to the rear brakes, and that if you have ever pulled the emergency brake up while the ABS is engaged ,.you know, the car drops anchors and you stop much better( old WRX that is)

PRESS THE PEDAL DOWN HARDER, AND BRAKES WORK BETTER,

this same principal workd in the Benzes at work,..customer's call in and say,..." yeah I saw the deer, then at ths last second,..the car stopped,.." EBFD works well, we just have to use it !!


ok,..I'm done with my .02

944 turbo guy

PS.. HOW TO TEST THIS THEORY YOU SAY?....drive 80-100, press what you call hard,..then as car is decelerating,....press harder, and you'll feel what I'm talking about.

Last but not least,..all the Brit-ish drivers @ the Subaru STI ride and drive were talking about the way the EBFD works, and how they have to STAND on the brakes to get the most out of them.

Just a note... if the rotors and pads are the same as the OZ spec STi then I think you'll find they're very soft. All you need is some braided lines, slightly better pads and some rotors made out of some decent material.

Any of you that have done more than 3000-4000 miles, go out to your STi and run your finger along and off the edge of the front rotor. Notice the lip? Exactly... the material is way too soft.

That's why I went and got myself a set of these...



DBA 5000 326mm two piece rotors... Mmmmmmmm

What is the damage on the walley on a set of brake pads like that. They look very nice any extra stopping distance

Probably best to have a look here:

http://www.dba.com.au/5000series/5654.asp

Mine ended up costing me $480AU... but I've got no idea how much the shipping would be as being a brake rotor they're pretty heavy. Drop them an email and see what they say...
