03' LX470 Brake Problem

[BReynolds]

I'm in a remote area of Montana and am having a hard time finding someone to help in repairing a leak. It appears that brake fluid is coming out between black plastic plate with electrical connections and aluminum housing.
Is it possible to fix something like this without removing entire master cylinder assembly?
Thanks in advance.

The leaks seems to be coming next to the black electrical box and housing. Is it ok to remove black box while unit is still installed?
Thanks

I have no experience with this ABS/VSC box there might be a danger of losing some of the internals ie little ball bearings and such. It is a pain to remove the entire unit but not impossible after you do it once you could probably do the removal in twenty to thirty minutes. First time maybe in an hour, lots of things to be careful about. For me most of the drama is in the interior footwell where my flexibility shows its true limitations. This seems like a project you would want to tackle on a nice clean table. My two cents.

you will have to take the entire unit out to serice it. It is not that difficult to take out.

There are few flters and O-rings. If you pull the plastic housing off the aluminum body, you might loose internal components. Take the whole assembly out and replace the ewashers. I saw a video posted by a guy in Africa servicing these O-rings, so we should have parts to fix it. If the OEm pump is near 250K miles, then it's best to get a brand new OEm master pump assembly.

Thank you for the response. I hope I can find the washers as the brake assembly is in proper working order with only 145k on it.

In Alder and nobody around here knows how to work on them.
