I bought a '92 lx Brake proportioning valve by mistake and i need to know if it will fit my 93 lx!?

 

There should be no issues as both cars have the same brake system?

 

The 92 through 95 are basically identical cars.

You could have your parts supplier look up the part number for the 93 valve and see if it is the same part as the one you bought.

 

all 92-95 EX sedans have ABS
92-95 civic LX that have optional ABS also have rear discs
a few 94-95 EX coupes have ABS

they are called EX-A & LX-A
A meaning for ABS (says in the honda owners manual!)

...that being said. If your '93 LX has ABS and the '92 LX that you got the part from had ABS you sould be good to go. But, all the proportioning valve does it distribute a percentage to the front/back brakes, say 70% to the front brakes and 30% to the back brakes. Do you have pictures or the listing you got it from. Also, a snapshot of your would be helpful.
