Alright, I don't think the brake issue is exclusive to Punto 1.2s. The very popular Maruti Swift 1.2 too has this issue and the newer Swifts were plagued with this problem. Seems it's merely an ECU tweak/update that solved it for them. Here's the article: http://www.cartoq.com/maruti-fixes-swift-braking-problem/ The problem is exactly the same that I was facing - the brake pedal hardens at lower speeds and wouldn't work. What can I do to get the ECU tweaked/updated?
