I had a brake problem. I use proton satria 1st model. I've put mivec half cut. the first workshop was to install my brakes in reverse. but it has been restored. in that it began to brake crazy. sometimes high. sometimes tight. sometimes low. I already change the master pump, brake kits and brake service. good for a while. after that he be returned. I was dizzy. I asked all of the pro in this case can give you some tips and ideas to solve my problem. Thank you. Sorry if my english language broken.
