both are fron CRX SI's.....brake master cylinders? Will the 88 SI work on a 90 SI? Thanks.

 

They all fit, but if you go 90 lx sedan I believe its the same size as a Da.
Correct me if im wrong

Yes you are wrong....very close but wrong. You want the 90-91 Civic 4dr EX it is larger and bolts right up. You stock one is 13/16 the EX one is 15/16.

 

I was told Lx so its an ex...oops

 

88 Si is the same as DX 13/16".

90 Si is 7/8".

it will bolt up. but the brake pedal travel will be longer.

 

thank for the in guys. I never knew different years had different pedal travel....

 

no, it just changes because of the different bore size doesnt match the piston size. 90-91 Si have large calipers and rear disc brakes.

but changing just the MC to a smaller bore size will take more pedal stroke for the same amount of volume. 7th grade math.
