for 5 days i look into the internet and i cannot find any info how to upgade a sierra 2wd cosworth master brake cylinder and parts codes.
I have changed the standard electric master cylinder to a standard sierra servo assistant and 22mm brake cylinder.I have focus rs brembo 4 pots front brakes and 4wd rear brakes.My pedal needs a lot of travel to brake.As i made a search to upgrade this problem is to put bigger diameter master brake cylinder,maybee from rs turbo.Is it direct fit or i need also the servo assistance?Where can i find used or new item and what is the finis code?Or something else for upgrade?
Please help as braking is very serious
