I bought 94 MX-3 GS auto last month

. It has a problem about brake.

When I brake, It needs a lot of distance to come to stop .

Then I changed rotors and brake pads for all wheels, but it's still the same.

Is the problem from Brake Master Cylinder???????

If the problem is from brake master cylinder, between the OEM Brake master and Tokio Brake master 601+1619, which one is the better one? I need some sugguestion. THANK YOU.......
