[skyline21]

Any sifu-sifu there can help me to solve my brake issue? I'm on evo 3 brake booster and master pump but after I installed the frt 4 pot caliper the pedal become lower position than before when you step it.

Any idea????

Skyline21,

Is the Evo 3 master pump twin servo ?
I experienced the same too. Changed from single to twin servo after using 4 pot, need to floor the brake pedal further down then only it can stop. I felt the brake is way of too soft. What did ur mechanic says ?

I also same configuration like you.My mechanic say is norm but I felt not rite:hmmmm: I think should be the master pump. I don't what is compatible beside EVO3? Do you have any idea? Any sifu to refer?I ever hear some people saying tat A32 servo can resolve the problem....Whether is correct or not I really hv no idea.

it can be adjusted but the thing is it must be just nice other it may cause ur brake jam. I think nothing much difference even adjusted and seems nothing much can be done.

Not sure abt A32 but let see the comments from others.

Recently I did a bleed to the brake system. Looks like it back to normal but it still under observation. Let you all noe again the result.
