Hello folks,

today I wanted to install my Brake Upgrade on my '03 TT.
The reason of the upgrade were the damaged(cracked) rotors and brake pads on the front, so I decided to install another complete system on the front anf back instead of the original brake system.

My Upgrade is the same like this: Click (Not bought from Vivid)
For the brake pads I have choosen the Cool Carbon Pads.

On the back it fits perfectly with the AP Adapters, the brake pads are laying down completly on the rotor(see picture 1).

But on the Front the brake pad is not touching the rotor completly(See pictures 2 - 5), the brake pad looks nearly 12 mm outside of the rotor.
I have tried to install the brake caliper without the AP adapters, but then it is not possible to install them because they are touching on the rotor.
Anyone has installed the system and got the same problems?
Is the big brake upgrade engineered like this?
I came from Germany, so this situation is not acceptable for street using and I am not allowed to run the car with this problems.
I hope some of you guys can help me with this problem.


Best regards
Bastian

 

THAT IS NOT RIGHT!

Looks like you have the wrong adapter brackets up front. Your calipers are mounted too far out.

Try taking the brackets off and use a washer or two. If you need more clearance try using some spacers. Make sure you are using the proper length caliper mounting bolts in either case.

Good luck.

I’d call /email Vivid....wrong kit!

 

Not sure I fully understand your issue, but if the issue is that the front brake pads have a gap at the bottom of the rotor as shown in your last picture showing a "12mm gap," that's the way it's going to be with this kit. The 997TT rotors are 350mm in diameter. The stock 996TT rotors are 330mm. The caliper spacers allow the larger rotors to fit under the stock 996TT calipers. However, they are still 996TT calipers with 996TT size brake pads. 997TT brake pads are a little larger than the 996TT pads, and hence will "sweep" the entire face of the rotor with no "gap" at the bottom of the rotor. The 996TT pads are simply not tall enough to sweep the entire face of the larger rotor. Hence, there will be a gap at the bottom of the rotor where there will be no contact with the 996TT brake pad. Completely normal with this set up . . .

 

^ But his pads are above the outside diameter of the rotors. That can’t be correct...can it???

Look at Front1.jpg third picture from the left.

 

"^ But his pads are above the outside diameter of the rotors. That can’t be correct...can it???"

I didn't see that in the photo until you pointed it out. I would agree that that is not correct. The top of the brake pads certainly should not be higher than the top of the rotor. I'd agree that if that's the case, there's something definitely wrong. Not sure what though as I don't have this issue with my set-up. I don't have the rear 997TT rotors on my car, so am not sure what the difference in the front and rear caliper spacers are, if any. As previously suggested, they may be reversed.

Back to square one . . .

 

Silly question, are they on upside down and/or wrong side? Or better yet, for the other axle?

 

you need the 997 rotors, 350mm

 

Hi,

thanks for the replies.Yesterday I have checked all the parts again.
All the parts are correctly installed and on the correct position.
The rotors are now from the 997 and have got a diameter from 350mm.
The complete rear brakes are fitting perfectly without any problems like you can see on the first picture above.
And it is not possible to install the AP pads from the front to the rear or reverse because they have different measures and can be only installed on the correct axle(They also have a signature with front rear on it).
The only problem is the too far out caliper to the rotor and because of this the not correct positioned brake pads.
So today I have checked the Installation with some washers for the clearance to allign the caliper and it is possible to position the caliper with the brake pads correctly on the rotor. So my solution is to mill the front pads to the correct depth and then it will work
But with the orginal AP front pads it is not possible to install the caliper correctly.
After Completion of the works I will show a picture of the completed front brakes. Thanks for your cooperation.

 

what does Vivid/AP say?

 

what is the thickness of their shim?

 

Double check that there is not some mismatch of parts. The brake pads are definitely sitting too high.

 

You mean the caliper? The pin that holds the pads is in and the spring the holds the pads down are on.

 

Yea maybe, one of the two is not right.

 

You should't need any modifications or "milling of the front pads" as you state. You have incorrect thickness spacer shims (too thick) on the front which are causing your caliper/pads to sit too far out from center. I would call Vivid before resorting to a "hack job" repair to make this fit. They can probably Fedex you the proper parts overnight. I wouldn't skimp on something as important as front brakes.
