VW Racing Big Brake kit product review

[tony_danza]

I wouldn't think it is a science - pretty much what you've got in your diagram looks ok to me.

[jabbalad]

no set dimensions, Just so it takes the corner off really, you want to try and avoid going too far into the surface of the pad tho as the further you go in the less pad surface you will have in contact with the disk

What you have drawn looks about right tho

Guys i'm really really upset I did the chamfer but the car continues to wobble. Now, it started to do a very pronounced squel when i drive normaly (when i don't brake). I don't know what to do. Tomorrow i will send an email to Sam and ask him if I can send the calipers, discs and pads back to England so that they can do some testing.
Something is wrong, something is not working properly.

Today i did a brake from 160km/h and i just felt like the whole brake is about the jump from the wheel.

i am  myself now very strange

[xht20]

believe me MAT, if England would had been closer to Romania i would come to show that i'm not crazy. Something is wrong. Does any of you has a picture of the spigot with the disc brake mounted?

[xht20]

I just received another email from Caparo in which they explained what they think  the problem is. They will send via Racingline the following: reshaped pads, spigot, and pad retainers.
I hope that this time works

As i understanded from the email the nuts on the modern cars are chamfered, and these act to align the wheel and keep it in position. So, tomorrow when i go to the workshop i will tell the guys there to  remove the custom spigot i made, unmount the whole brake kit and mount it again more carefully.
Hope everything will be safe when i mount the wheel only in the 5 bolts/nuts (don't know the correct term).  

[MAT ED30]

thats good news and take some pics of the parts when they come 

[xht20]

i will do so MAT

After some mails with Sam, we've decided that even after the installing of the new parts the problem isn't fixed i will send them the brakes for some tests. All i hope is that we solve this before 28th of April (when i will leave to Nring)

....Do you mean the wheels bolts? They are not "chamfered"/cup-seated on all modern cars. Some alloy wheels need them (OZ for example) and others don't (oem VW Monza's for example).

You can see by looking at the wheel which bolt type is needed. I think VWR should have supplied you bolts and whoever fitted the wheels should have seen if they were the right type or not.

[xht20]

I got a type of bolts from VWR and they are on the car. Tomorrow i shall test them to see if there is any improvment without the "spigot" extension i did

[jabbalad]

Take a picture of the bolt VWR sent you TEFF, the bolts that came to me in the kit were for an aftermarket alloy wheel, Matt didn't ask if i had aftermarket wheels either so i presume thats what they alwase send out?
If so you could have the wrong bolts for your wheels (not trying to pick fault, but there must be a reason somewhere along the line for the wobble)

[xht20]

Here are the bolts, and i measured my hub's length, it has 13 mm
I removed the spigot extension i made and took the car for a ride. The result is the same, it still wabbles a lot and very powerfull

[QD MBE]

Do you have a dial test indicator (DTI)  may be worth measuring the run out on the disc, this will check the disc is sitting correctly, or if the disc is bent.

[tony_danza]

Is that a cone/rounded seat on the bolt? Is that correct for your car - or are your original ones a taper?

[xht20]

i didn't understanted very well the question (damn i skipped the English class)

all i can say there bolts came in the VWR package. the bolts and those rounded nuts
