Brakes upgrade (from A4 B7 1.8TQ to A4 DTM 2.0TQ)

[aloakos]

I've just upgraded my brakes from stock 1.8T to A4 DTM 2.0TQ.
The diameter is slightly larger but the thickness is more (new 320X30MM 5/112; PR-1LA, old 312X25 5/112)

Also the brake pad surface is 30% more.
The job is very easy and no special tools are needed. The only "catch" is the bleeding of the system, where two man are needed and o bottle of DOT4 fluid.

I used Ferodo DS2500 that have no warning cable so I had to cut old cables and connect them together in order to avoid brake pad warning in inst,cluster.

I use 17'' wheels from A4 B8 7.5Jx17 ET42 - 8K0601025K


Parts Used:
1 4F0615123 brake caliper housing; left 1
1 4F0615124 brake caliper housing; right 1

7 8E0615301AE brake disc (vented); punched; 320X30MM 5/112; PR-1LC 2

18 bracket; see illustration:; 611-20 2


The improvement is HUGE, especially in high speeds and in mountain roads.
Enjoy

Just an update.
The brakes I had installed were used so the thickness of used brake pads allowed the wheels to fit.
After renewing the brake pads the wheels wouldn't fit so I had to use a set of 10mm wheel spacers.
