Title: Rallye S brake system
Post by: simonpen on 15 September, 2020, 04:31:53 PM
My very knackered rear callipers have 35mm pistons. I was expecting 33mm. Did the S have larger pistons? ta

Usually, yes 35 mm. The 33 mm size was normally fitted to the 1.2 coupe, Andrea

Aren't the Dunlop pistons always measured in inches (marked on the top ) ?

Also, does anyone know the diametre of the master cylindre for the "S" - is it 19mm ? I think my non servo GT has an 18mm bore

Thankyou Andrea, perhaps I was thinking of my earlier car. My master cylinder is 19mm.

Originally all fulvia rallye S and GTE both had 19 mm brake master cylinders (plus servo). Other S1 cars had 18 mm (non servo).Andrea
