According to the mechanic, the Cinquecento banjo bolts will not fit the brake pipes. I can infer, from this, presume, the 126 brake pipes are not compatible with the Cinquecento banjo bolts. He says he needs to buy new banjo bolts. Is it two M10 x 1mms Banjo bolts to suit the calliper thread at the flexi hose inlet as per Rusty's suggested required parts?
