I've been reading for the last 4hours looking up information about rear drum to rear disc conversion. I have a 96 4D Civic Lx with GSR swap. I have Del Sol rear disc conversion in the back but i don't think the previous owner changed the Master Cylinder and the Prop valve. So my RR(right rear) brakes locks up some times(only when i press the brakes) and it seem from my research that it has to do with the prop valve.

I have access to a 98 4D Civic Ex automatic. I believe its ABS and i was wondering if i could take the prop valve off this car and use it with my 96 civic. Or do i have to buy a 40/40 NON ABS prop valve and if so what cars have this kind. I know i can use the Master Cylinder off the this EX for my LX. Just not sure if this brake prop valve will work.

Sorry im new to this website and if i missed a thread that had more info i apologize and i'll continue looking but much appreciate the help.

 

Get a prop valve fromany 96-00 civic, DX coupe/hatch, CX, SI, HX

 

Thank you i will look for one!
