I have been having some braking issues lately, and I realized that my ABS unit is leaking brake fluid.

So on saturday, I removed the unit and replaced a couple O-rings in the abs pump because I thought that the pump might be leaking. Everything was fine for a couple days, but today it began leaking again.

I felt under the abs modulator and the entire bottom was covered in brake fluid.... so I took the unit out again and I was still unable to figure out where exactly it is leaking from.

So I disassembled the entire thing, including the pump, reservoir, and the individual solenoids and cleaned the fluid off of everything. I put it back together and installed it in the car with some new fluid, but I left all the brake lines disconnected. I started the car and let it pressurize the accumulator. Then I took the ABS unit out and set it on the workbench and I am leaving it there overnight so I can hopefully figure out where it is leaking from.

Any of you experienced anything like this? It just started happening all of a sudden...

How much does it cost to replace the entire ABS modulator unit? I wonder what they go for new/used?

Any info will be appreciated.

Hi,
I have a '96 GSR, and I have also noticed in the past couple of weeks that my ABS unit is leaking. It is a very slow leak, and i am just now beginning to troubleshoot it. I started by buying some flare wrenches and tightened up the brake lines - might as well go for the obvious first. I am now monitoring it. I still don't know yet where the leak is coming from exactly. I am hoping it might be from the reservoir - that would probably be the cheapest...
I'll post up if/when I find out more.

Isn't the ABS modulator hella expensive? Like, $600 or so?!

 

I think it is closer to $1000
