from the looks of it you havent done anything regarding the breaking system.I will suggest you to upgrade them,Further more there is a high probability that the hand break doesnt work propwerly (common problem in the cars i have seen) if thats the cse imort genuine cables from abroad dont use the one you find from kabar they will stop working.
and dont forget to get all the gauges in full working order.test them 3-4 times atleast .
work done once properly is way better than khuwari
