I have a JDM Nissan Sunny to which i have upgrade the front brakes to AD22VF and looking to do the rear disc conversion soon
The car come with a 3/4 Master cylinder which is not adequate i want to do the 15/16 but have a little concern my model uses the 4 pipe Master and proportional valves and i got a 2 pipe 15/16 Master from a friend can it work
don't know how i would work out the proportion
