Hi guys I'm looking for help from the Cinq/sei section,I bought a Bravo HGT rear brake set up conversion for my Cinquecento project but I noticed one of the sliders was a bit wobbley! I pulled it out and sure enough it's different to the other slider on the hanger,is it supposed to be like this? if not does anyone know where it's from? The one on the right is the wobbly one which ssems to be stepped,where as the one on the left is the same thickness the whole length but has 3 flats? Thanks Guys!
