TRACK CAR --- ADM Sprinter with STD master cylinder & booster.

1. I 1st ran the car with RX7 caliper / Mini disc on the front ---- stock ADM Drum rear ---- under hard braking massive rear lock ups.

2. Then fitted JDM rear set up --- STD DISC & calipers , TRD 2 WAY diff ---- now the front brakes lock up , big time.

3. Just fitted Rear Nissan S13 disc kit --- using STD JDM rear calipers , have not used the set up in anger yet. But up and down the street if feels ok.

MY PROBLEM IS THAT I JUST NOTICED THAT STD MASTER CYLINDER IS LEAKING !

Did a search on MASTER CYLINDERS ----- lots of choices --- too much info --- the right one required seems to depend on what brake set up you have --- now not sure what to replace leaking unit with ?

So what will best suit my set up ???? Nissan r32 , PAJERO , STARION , TOTIKO , JDM STD ??????

ps --- Want to keep the STD booster !!!
