Brake fluid trasfering to abs reservoir

[3gcvcd16]

I have had my 93 accord ex wagon for 4 years now and i have run into this problem i bleed the brakes with new fluids in the reservoir and with in a couple off days i loose it all cause it is transferring to the abs reservoir and is overflowing. My abs never worked cause of a bad wheel sensor and never cared to fix it, but this problem is killing me and i am going to sell the wagon and want to fix it... What can it be??-

You have a bad modulator. More specifically a blown solenoid seal. Is your abs functional?

My abs has not been working since i bought the car 4 years ago. Where can i find this modulator and solenoid seal

[sonikaccord]

The junkyard or the classifieds here. Or you can follow the abs delete DIY and eliminate it completely

Thanks for your help i would like to keep the abs cause i don't want to go to all that trouble removing it

I would like to replace the seal anywhere i can find a diy on how to fix this

I can post the rebuild instructions. If you choose to follow through, you can post a DIY.

Edit: you will also have to source o-rings for the pistons

The diy would be helpful. The seal you say i need to replace are just the piston o rings?

I have a similar issue. I'm leaking brake fluid out of my ABS reservoir fill opening. About half a reservoir every 6 months. The top is always wet and everything in the system is new except the module. My guess is when the ABS activates I purge fluid from the pressurized system into the ABS reservoir causing it to eventually overflow. Any ideas?

Pics are up, obviously.
@domesticated The pump is feeding back into the reservoir? Strange, maybe it's pushing past a piston seal. I'll have to look at the block diagram and see how the pump is connected.

Thanks for the images above, I'll get around to it this summer. Probably needs a cleaning and new seals anyway. But I was thinking it was moving past the seal somehow.

BTT....
Has anyone successfully been able to change any Seals or O-rings and correct this Brake fluid migration issue?

Mine is so bad at this point I have to transfer fluid back to the master cyclinder about once a week...lol

Thanks,
Mike

I have this problem as well on both of mine. At least with one of them the brakes still work, I just have to pay attention to the fluid. On the other, they barely work at all, even with a new master cylinder I have some spare pumps and modulator, but haven't had the time to try and see if they would work.

time to epoxy some brass barbs to the containers and run a transfer hose from the abs to the master lol throw a filter inbetween for scene points of your mod
