Ok ... I have stoptech 13.1 rotor setup.. I did the bed in process with no issues...Today after some extensive driving I encountered a slight metal grinding sound while pressing the brake only... while crusing I have no problem.. What is this? Did anyone experience this sound before? help please

 

Its called "squeaky brakes" I have it and I do not like it.

Get use to it, it aint leaving but it does not hurt anything.

 

That's not normal. These brakes have the potential to be as quiet as stock brakes, depending on pad selection.

What type of pads are you using? Are they the Axxis Ultimate pads that came with the kit? Or are they some sort of track pad that you are running on the street?

How many miles are on your brake kit?

 

I have a at least 6000 miles on my stoptechs. Tried another set of axxis pads, did the bed in process, again, and they still squeak when slowing to a slow stop. (1000 on one set/6000 the other)

I do not like it!!!!!

 

they are the axxis pads that came with the kit... I have less than 1000 miles on them ..I never had a problem with them before. It's just till recently at a long drive it happened. It also seems like when the brakes REALLY heat up I get this light grinding sound / squeak... Im calling Stoptech just for kicks..

 

is there any other pads that we can use?...i used to have a wilwood kit for my acura..i had to change compounds for my pads and it stopped..any other pads we can get..i need them too..it ****ing sucks..

 

There are a ton of pads you can get for those calipers. See: http://www.zeckhausen.com/StopTech/consumables.htm

If noise and dust are your number one complaint, I would consider the Axxis Deluxe Plus. Very low noise and dust. BMW owners are plagued with dust from the stock pads and many of my customers order the StopTech front kit along with a set of Deluxe Plus pads for the ST40 calipers and another for the rear OEM calipers. They are only $54/set.

I'm not sure I got an answer to my question about the Axxis Ultimate pads, though. Are you running these on the track? The Ultimate, despite its 1100 degree F max operating temperature, is not a track pad and will give you deposition problems if you run it there. The pad which has been getting absolute raves for track use is the new Performance Friction 01.

 

This is just an FYI...I just got off the phone with Stoptech.. I explained the hisssing sound slash grinding sound comming from the brakes.. He told me it's actually the pad(Axxis Ultimate) making this sound while its rubbing against the slots in the rotor. He said it's normal with this pad because he has the same problem on his VW. He's willing to give me the pads of my choice at a discounted price... So Hawk HPS here I come.. LOL

 

I was talking to StopTech tonight and they tell me you still haven't paid for your kit and gave them a bad credit card. Perhaps this is the "no-pay squeak" that kicks in if your credit card comes up as bad!

For the street, you might want to try swapping in some Axxis Deluxe Plus pads and then bedding them according to my instructions at: http://www.zeckhausen.com/bedding_in_brakes.htm

React3, you must have spoken with Paul since he's the VW guy at StopTech. I'm not sure I would agree with him that the noise is "normal" with the Axxis Ultimate pads. I have always been able to quiet them down to no squeal by bedding them in per my method above. I spoke with him about your post and he didn't mean to give the impression that the Ultimate pad was noisy. Properly bedded, it doesn't have to be. Try the technique described on my web page and see if it helps at all. I would be interested to hear about your results, even if they are bad.

And all_bark, you really should pay for your StopTech brakes. Who knows? Perhaps the pad noise will go away after your credit card clears!

 

Hey Dave

Thanks for all the information you have provided. It helped out a lot on the install of my Stoptech's (I had installed pads once in my life). Everything went very well thanks to the information you provided....

 

Which information helped? (Sorry, but I forget what I've posted. Too many boards, too little time! ) I did also write the 350Z installation manual, so perhaps that's what you are referring to.

Have you bedded those puppies in yet? Any plans to track the car? If so, here's a little tidbit of info: For intermediate to advanced drivers running the 350Z with StopTech brakes, I have found the Performance Friction 01 pads to be the most trouble free and consistant pads available. There have been no reports of pad deposition, which is common with the Pagid Orange pads. And the pads are OK to be driven home from the track event and then switched at your leisure, after you've recovered from the race weekend.

Please, please do not run the Axxis Ultimate pads on the track!

 

Both your install manual and the info on your site about bedding the pads and bleeding the brakes (not in that order).

I do plan to hit the track, so I will take your advice into account (I do currently have the ultimate pads on, but do not plan on racing for at least a few months).

One question, if I remove the Ultimate pads for the track, can I put them back in after the track time?

 

Yes, you can. You will have to rebed your brakes each time you switch from street to track and then back to street again. But that's not a big deal. I consider bedding pads to be one of the most fun things I do! Just makes sure you pick a road with light traffic and have your radar detector turned on.

Rebedding pads is typically less prone to trouble if you stick with pads that are within the same "family" of pads. For example, the Pagid Orange pads play well with the Pagid Blue pads. And the Porterfield R4 play well with the R4S. An exception to this "family rule" is the Performance Friction 01 pad which seems to be the "Type O" of brake pads. I have yet to see any deposition issues or compatibility problems between the PF01 pads and any street pads.

 

I'll add one more pad that plays well with the AXXIS Ulitimates, the Carbotech Panther XPs. I was told by Carbotech to expect some issues with the XPs and Ultimates, but found no problems whatsoever. Both pads reacted well to each others compounds and wiped the rotors clean on each bed-in.

Dave, how do those Performance Friction pads wear? Because of car troubles at my last event, I only got in 3 of 8 sessions. However, I still mananged to take a little over 1/16" off of the Carbotechs. If I had finished the weekend, I fear I would have easily burned through half of the pads.

 

I have the brakes that came on the car. Have had a lot of brake noise. They finally gave up and are putting a new set on today. Also the window stops finally got put on. Now we are discussing how hard it is to release the hatch from under the stabilizer bar. I have 6,000 miles on my car.
