Brake Rotors

[clay5523]

Have a 2008 TT with 19" standard wheels with regular brakes(iron). Can someone tell me what the diameter, in mm , the front and rear rotors are?

[Loren]

Rears are 350 mm.

The fronts should also be 350 mm unless the GT2's 380 mm rotors were installed.

Plus there are different rotors for center-lock wheels...

If you want PM me your VIN and I will look up what was factory installed.

Thank Loren. PM sent.

[Loren]

Ok thanks.

In your case your brakes are both 350 mm.

One more question:

Are the fronts 32mm and the rears 28mm in thickness??

[Loren]

New thicknesses are:

Front: 34 mm

Rear: 28 mm

Wear limits are:

Front: 32 mm

Rear: 26 mm

Peak-to-valley surface roughness of brake disc after machining (max.): 0.006 mm

Thickness tolerance of brake discs (max.): 0.02 mm

Lateral runout of brake disc: 0.03 mm

Lateral runout of brake disc when installed (max.): 0.06 mm

Thanks again Loren. That deserves another site donation. Sure saved me a lot of time.
