For 1.8 ts with non vented discs ( I mean come on Alfa
I had warped discs and so I had to try something to upgrade the standard set up .
Changed the pads ,Ferrodo DS pads front (comes with pad sensors) and rear.
Tarox Sport Japan drilled/groved Discs.
Brake fluid changed.
I do fast (80-ish
) speeds on the A3 about 20 mile trip one way, mostly 5th gear work continuous non stop.
I find that the improvement is very noticeable certainly less warped feel.
The pedal "feel" much improved. (poss due to new fluid/pads)
As I don`t brake so often ( no stop/start motoring) the pads tend to squeal more, some hefty brakeing cures this but will come back.
The brake discs also make a noise when pedal applied ( sounds like a whooshing noise) poss due to the drilled holes?
Would I refit these items again?
Might try Tarox pads (might stop squeal).
Smaller number of grooves ( 4-6) on next Discs.not drilled.
On reflection my previous 146 1.7 16v had superior brakes, ie vented discs though earlier ABS system. I could brake with great confidence at very high speeds and very heavily int sharp bends.
The above mods make the braking set up on my 156 acceptable BUT I haven`t tried the DS2500 pads or 2.0 set up to see if that set up is better than the 1.8ts.
AutoItalia did a test with a 156 1.8 ts which gave the resulting brakeing distance and pedal pressures using various standard/after market set ups.
very useful, if you can find the article read first before buying ANY new brakes. I cannot remember which issue it was in , some one on the forum might.
I hope this is of some use.
