Brake Master Cylinder

Anybody know if an ej9 1997 hatchback civic uses an ek4 brake master cylinder looking to convert the rear into discs, need to know if it need to be changed, any help would be appreciated.

The EJ9 master cylinder is not the same. The EK4 uses a 15/16 master cylinder. You can get away with using the standard EJ9 one but you will defiantly need to change the brake distribution valve to one from a honda with rear discs in order to make the rear disc conversion work properly.

still the question is if you have an abs do you have to replace an abs pump or not?
