System components

Front axle wheel brake

The brake calipers are identical in design and 
principle of operation to the brake calipers on the 
Audi A3. A zinc-nickel coating is now applied. Brake 
calipers are optionally available in a grey finish. The 
brake discs for the 16" system have been adopted 
from the Audi A3. The brake discs for the 17" system 
are a modified version of the discs used on the Audi 
A3. This change was necessary due to the modified 
rim geometry of the SST wheels.
The Audi TT has new brake hoses with modified 
holders on the swivel bearing compared to the Audi 
A3.The 16" and 17" splash plates have been adopted 
from the Audi A3. Break pad wear is measured in a 
conventional fashion on the interior lining of the left 
wheel brake. The 17" system is equipped with a 
vibration damper. The damper is attached to the 
brake caliper by the lower fastening bolt.

Brake system

Rear axle wheel brake

The brake calipers are identical in design and princi-
ple of operation to those on the Audi A3. The brake 
carriers have been modified since the Audi TT has 
wider rims than the Audi A3 and, because of this, 
the requisite clearance for the handbrake cable 
would not have been assured had the A3 brake car-
rier been adopted unchanged. 

381_017

Compared to the Audi A3, the brake calipers have 
been shifted 10 mm further inwards. Two new 16" 
and 17" splash plates are used. The brake hoses 
have been modified. In the Audi TT the transition 
point from brake hose to brake line is located on the 
side member (it is located on the subframe in the 
Audi A3) .
