Does anybody know the dimensions of the Evolve rings pertaining to <A HREF="http://www.stoptech.com/products/img/0605AeroRotorDataSheet.pdf" TARGET="_blank">this chart?</A> If anyone happens to know can you please post it here. Also does anyone know who makes the Evolve rotor kits?<p>Thanks,<p>Denny

Re: Evolve Rotors (wrxownr)

Contact Martin at GiroDisc...he will have all your answers.<p>[email protected]<p>949-350-6194<p>You can also talk to Pram here on SS. I am also talking to Pram and Martin since I have one of the first sets of rotors as you do. Let me know if you hear anything.<p>I feel your pain, Denny.

Re: Evolve Rotors (pie_ya)

Thanks ... I contacted Girodisc today and they sent an e-mail saying they would be closed until the July 7th. So I'll be e-mailing them on the <br>8th and asking about replacement rings. It looks like the rings are going to cost around $250 a piece. Hopefully, if we can the specs for the disc, Stoptech will have something we can buy. Those Aerorotors look sweet.<p>Denny

Re: Evolve Rotors (wrxownr)

My plan is to get them to turn my rotors to fix the vibration issue and replace my rear hats with their correctly sized iron ones they are testing so I can park on inclines and declines again.<p>I hope I don't have to replace the disks though I have about 16K miles on them.

Re: Evolve Rotors (vizwiz)

You remember the thread about the Evolve rotors a while back where the first set of five (I believe) had problems with them...the rear hats were the wrong size (or they didn't include the e-brake pad) and too soft and the thickness of the rotors varied so much that they caused vibration when braking from higher speeds.<p>We are still dealing with that right now and trying to get that resolved. It sucks when you can't park on even a slight decline and your car shakes when brake from 60+ mph.

Also you are referring to two different issues. The e-brake adjustment has nothing to do with turning your rotors. The reason you (and everyone else that has the first gen rotors) have to keep adjusting their e-brake is because the hat insert is getting eaten up from because the Evolve hat (unlike the stock hat) is soft and not made out of iron (like the stock hat is). Plus I believe the stock hats have an e-brake pad that gets worn down instead of the hat itself. Note, I am referring to the cylinder hat itself which is only on the back side of the rear rotor, not the disc or any other part of the Evolve brake rotors.<p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>wrxownr</b> »</i></TD></TR><TR><TD CLASS="quote"><br>Evovle should replace the discs if they know they are soft and there is a problem!

And no, Evolve did not say they'd replace them, Martin at GiroDisc stated that would resolve the issue.<p>I completely understand your frustration...I get the vibration issue and the rolling-a-few-inches after engaging the e-brake, plus I can't park downhill whatsoever and uphill on slight inclines only. I will need to readjust my e-brake soon if I don't hear from them soon. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">

Is everyone sure that the hat is wearing and not the e-brake pads? I haven't pulled them off yet to see. <p>Evovle told me they have a solution for me in a couple e-mails but they have not made an offer of what the solution is (It's been close to two months now since Evolve and I first started talking.) I'll be talking to Girodisc as well here soon.

Re: Evolve Rotors (wrxownr)

The reason Evolve hasn't gotten back to you is that they are probably waiting on Martin to give them a final update that the hats will work.<p>Sorry, didn't realize you understood both issues. I believe GiroDisc is a middle man between the actual manufacturer of the rotor disc and Evolve. What might be going on is that GiroDisc has a manufacturer that makes a disc that will go on the rotor assembly and they put it together and sell it to Evolve according to Evolve's specifications. I really am guessing on this.<p>According to Martin, Volvo also has a bad design with regard to the e-brake system in that the pads (or something around the pads) move around when you drive unlike an EVO that is secured to the hat. Martin explained this issue to me but I wasn't able to understand exactly the problem.<p>I am also pretty sure the hat is wearing and not the e-brake pad because of the soft aluminum (or whatever they use) versus the iron hat and e-brake pad backing that the e-brake pad rubs against when you engage the e-brake.<p>Hopefully this will be resolved soon. I was under the impression from Martin that he wanted to resolve this issue and do it correctly. I don't really know who is to blame...maybe it is neither of them and simply the manufacturer (if it is not GiroDisc themselves).

Re: Evolve Rotors (pie_ya)

The supposed solution is for the rings (vibration) not the hats/e-brake ...

Re: Evolve Rotors (pie_ya)

I really don't have a dog in this fight, since I do not have this product, but I would caution going directly to the prime vendor's subcontractors.<p>If it is an Evolve product it is up to them to resolve it. If you go to their subs they have an opportunity to say they tried to fix it, you went to their sub, you left them out of the loop etc., etc. <p>I am sure these are all ethical companies that want to do the right thing, but just in case, you do not want to weaken your position.

Re: Evolve Rotors (rogersampson)

I was only looking to go to other companies to purchase rings. I still want to work the issues with Evolve however. I'm still interested in who makes the brakes for Evolve as well.

Re: Evolve Rotors (wrxownr)

Guys:<p>There were basically two problems with the Evolve two piece rotors. The first problem is the vibration when you brake (medium to heavy and not in light braking) and the e-brake problem (in the case of customer who bought the first five sets of Evolve rear rotors.<p>The first problem with vibration which is caused by uneven thickness of the rotors can be cured by turning the rotors which is why (according to Martin at GiroDisc) they are currently turning all their rotors before shipping them to the customer.<p>With regard to turning the rotor in the case of the above problem, you are supposed only to take very minor amount of thickness from the rotor unlike turning the rotor when you have warping problem<p>The second problem with the e-brake is mainly caused by the rear drum hats being larger in diameter than the stock hat. However this case only occur in the first five sets manufactured. I(awdnut), Pie-ya, Denny (WRXowner), one of RKelly's buddy are pretty much the four customers with these wrong sized rear hats (the other remaining set Evolve never ships).<p>My V70R had both problems and currently got both of them resolved by Martin (Girodisc) by having the front rotors turned (by GiroDisc) and the rear rotor hats replaced with the correct diameter.<p>I tried to resolve through Evolve but got frustrated by their response/service. Martin at GiroDisc (the Evolve rotors supplier) has been super in resolving my issues with the EVOLVE rotors.<p>HTH,<br>

Not sure if you are right about there being 5 sets of 'over-sized' rear hats, I got mine about a year ago and they are oversized.<p>I also get that pulsating pedal problem when braking when they were on, i have since removed them. Wonder if Evolve can replaced the rear hats?<p>Wonder does Evolve still monitor this forum.<br>

Re: (Randall)

The rotors are a problem Evolve needs to address. Sean is going through this too.<p>I've only noticed mine shudder a little when going down a steep hill. Nothing too major.

Re: (frankhoffy)

I'm not 100% sure if my rear hats are over-sized. I'll pull my rear brakes and measure the diameter of the rear e-brake part of the hat. Then I'm going to measure the thickness of that section as well. Maybe somebody who has recently purchased the Evolve brakes can measure theirs so we can compare. <p>When I first put the Evolve rear brakes on I did not have to adjust my e-brake, but just before I bought those brakes the dealership replaced my rear discs because they were warped. I since have adjusted my e-brake because the handle was moving close to 90 degrees. Now when I park and pull the e-brake the car rolls a little so now I have to pull it harder so it does not roll. Since the adjustment it's almost already to the point where I'll have to adjust it again.<p>Denny

Re: Evolve Rotors (awdnut)

Pram, did Martin replace your rear hats with the iron ones and what was the amount of wear with the soft hats? And how is your e-brake working now?<p>It's funny...when I mentioned to Don that my rear hats were larger than the stock hats, he told me that was not true and that they were exactly the same size as they should be. They didn't even realize the problem then.<p>I have been trying to contact Martin for a couple of weeks now and he hasn't responded. I am assuming he is on vacation or off on travel or something. And if he has fixed the problem on your car, why hasn't he contacted those of us that have the same problem? Or why hasn't Evolve done the same?<p>I am afraid of coming back to my car and finding it parked into another car after it rolled back or even worse. <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0">

Personally I have not measured the internal diameter of my rear hats, all I know is that when they were installed (sadly, not anymore) my handbrake lever goes way up and my car rolls a little before it stops while on a slope.<p>It be great if Evolve can make good on this 'defect'. However, it looks like Evolve does not monitor this thread anymore. How sad!<p>RT
