Akebonos not up to heavy track use!

rbratton · 10-20-2009, 10:56 PM

I ran at Little Talladega last month with Carbotech XP10/8 combination. I was still using stock brake fluid, but my only problem was the bleeder screw on the left front caliper outside slightly loosened and leaked a bit. Luckily the brake paddle gradually softened and I was smart enough to pit in and check it out. I too was hitting around 110 on the straight and braking extremely late. Compared to my 350Z, I was pretty impressed with the brakes. Little Talladega is definately harder on brakes than most of the tracks I've been too thus far. This weekend, I'm heading to Putnam Park. I've upgrade brake fluid to Motul and I'll have 275 width tires on the front for a few runs. This should be a good test of the brakes...

Where is Putnam Park? I think I've heard the name before, but not sure.

btw,
the new brembos proved to be excellent at CMP last weekend.

Doesn't Akebono make brakes for F1 cars, wtf?

As far as I know, Brembo, Carbon industry, and Hitco (or Hitko) are the 3 brake makers for F1.

Wow, 1st I have heard of that. Looks like there are 4 brake suppliers in F1.

I have a track day on the 31st...my 1st track day in the Z. I am very hard on brakes so I will soon find out how well these brakes can hold up. Motul RBF600 fluid and Carbotech XP-10's are the only brake mods for the track thus far.

Mike · 10-21-2009, 03:54 PM

check your pads after the track day too. I just switched to ferodo DS2500s in the rear to match what came with the front brembos and in 2 and a half days at CMP they were pretty much to the backing plate. I've never seen a car eat through rear pads so fast.

Putnam is East of Indianapolis, IN. Turn 7 will test your brakes.

To the question on brake seals: I have never found any that last with hard track use. The seals on Porsche/Brembo Big Reds never lasted more than a few weekends. Keep a can of brake clean and clean the pistons BEFORE you retract them at pad change time. That should keep the bores clean.

Surprised me too, although I think they've been supplying McLaren for the past 2 seasons

My point is that I'm surprised they're performing so poorly..........

import111 · 10-22-2009, 02:09 PM

Well, so far there is only 1 person that has posted this issue, and from what it looks like it is just the dust boots that were damaged, which is not a big deal. My STi's Brembos dust boots were very cracked after a few track days and I never had issues 10 track days later.

It's near Terra Haute, Indiana. It's similar to talladega but a bit longer at 1.7 miles.

AP Racing supplies more F1 teams than anyone else. SGL/Hitco and Carbone Industries supply the carbon-carbon discs and pads, but AP Racing or Brembo supply special calipers and engineering support to all but one team based on the latest information that I have.

Akebono bought the Williams deal, much to the disappointment of the team's engineering staff. AP Racing had been the supplier, but they do not sponsor anybody in any series (which is interesting, since they supply the dominating calipers -- the RadiCal line -- in NASCAR these days, a series that is all about sponsorship!). If you remember the financial hot water that Williams got themselves into in 2007 ($100M worth), you can easily understand the changes they needed to make in order to stay afloat.

All that said, Akebono's F1 calipers have absolutely nothing to do with the design and manufacturing efforts for their OE programs. In this particular case, the G/Z Sport calipers are for primarily for looks.

Really? Akebono derives NOTHING for OEM products from racing? Really?

Race on Sunday, win on Monday?. I'm probably talking out my azz here, but it sounds weird, wtf.

CMP and TGP are two of the toughest tracks on brakes. They just eat up pads, rotors, and everything else. If your brakes hold up well at these two tracks, they will have no problem at Road Atlanta, VIR, Barber, Roebling...etc..etc.

There are only a handful of brake upgrades I would use on track, and Brembo and AP, and Stop Tech are three of them.

rbratton · 10-26-2009, 02:26 PM

Carbotech XP10/8 combo with stock brakes worked great at Putnam Park this weekend. I had 275 tires up front and they still held up fine. I did however hit limp mode even with an oil cooler installed.
