I have a 1993 Honda Accord Lx with locking brakes and i was wondering if it is possible to transfer the anti-lock brakes from the EX over?

 

These would be a major project w/ many challenges. It would be cheaper and easier to trade for a car w/ ABS.

Some of jobs:
1) Modulator installation and tubing runs to be spliced into existing system
2) Wiring harness swap from donor vehicle to have the interfaces for ABS control module and ABS modulator. This activity would be especially challenging and may involve a large number of changes.
3) Installation of ABS control module (not sure where it was on 93 Accord, under dash on later models).

good luck

 

you don't want to swap ABS. For one it's a HUGE PITA 2nd it's costly when your gas cyl goes bad (and it will) Actually all of the ABS guys disable ABS. I looked into this too when I was swapping my rear disc brakes from my 94 ex to my 93 lx. It's not even worth it. But if it something you want to do you will need...

All the ABS components (computer/rotors/sensors)

you will need to under dash wiring harness from the ABS car. It’s the only way to get the correct wiring for the ABS computer. Then you will need to wire up ALL sensors for the rotors. I'm sure there is more that you would have to do but that’s all I can think of off the top of my head.

This will cost you more than it's worth to swap over. But you can just swap the rear disc brakes over to your 93 and don't use ABS. That’s what I did
