thx for your reply Izso, my case is like this kinda complicated, recently last month my brake failed reason is master cylinder pump leakage so changed it to a new set. servo still same didn't touch so i not sure servo got problem or not. after that ok for 1 week and then the pedal starts to behave weird again sometimes keep sinking sometimes not sinking so headache, after that they did a bleeding again, after bleeding still the same problem brake sinking, then perodua service center changed my abs pump to a new set. so far still can feel spongy but not so serious. and i just changed my brake pad few days back bendix general ct (for your info my previous original brake pad haven't change before since first day, means 3 years already still left 50%) my driving pattern not heavy footer and gentle soft brake style, after change brakepad the full bite is better already but still can't eliminate the sponginess when applying middle pedal pressure crapy feel. my model is 2015 manual myvi icon blue, car age 3 years 3 months. u been using improve braided hose is it ok? im impressed last for 10 years wow. recently have survey it too they quote me improve braided hose price around rm386 with gst not include installation fees yet. im so confuse now wanna install this item or not. yes true very depends on the installer and expertise. any shop recommended? by the way i googled can't find any brand named superstreet, only have supercircuit, is it supercircuit brand u mean?
