i have a ef with DA rear disc . will 99-00 si e-brake cables work?

 

NO.

if you have a crx then you NEED 91 crx si e-brake cables
if you have a civic hb or sedan you can

 

wait. you just confused me. if i have an ef hatch or sedan i can use the 99 si cables? or not?

 

yes. with because the HB and sedan are longer than the crx you can use the cables from the rear brake donor, in your case the 99-00 si. because the crx is shorter those cables are too long and will drag, in which case you WILL need the cables from a 91 crx si which are the correct length.

or to make it simpler:
88-91 Civic Sedan 90+ cables from donor car (minus del sol)
88-91 Civic HB 90+ cables from donor car (minus del sol)
88-91 Crx cables only from 91 crx si

i am not sure if the del sol cables will fit the crx. i know when my buddy attempted to put del sol e-brake cables from a del sol on his 90 HB they were way too short.
