Re: Brake leak

If it's not coming from the master cylinder or its lines above it, it's the combination valve itself.

Re: Brake leak

So, are we looking at the proportioning valve in those pics?

Rotated 90 degrees (opposite directions) from vertical in each respective pic?

So, basically you are showing us a tilted and close-up view of this?:

I think I'd want to know what the master cylinder assembly above it looks like.

It could be something as simple as you spilled brake fluid when you were refilling the reservoir after the light on your dashboard came on.

If you wipe the fluid off that area, does it reappear?

Re: Brake leak

replace the prop valve , the lites on because thu fluid spits out thru the leak .and sucks air in so change the valve and bleed the breaks ,that should do it

Re: Brake leak

Because of thread differences, 82-88, won't fit late 89 to 92 cars. I'd recommend replacing with the combination valve appropriate to your car (for example, pick one one from a drum car is you have drums brakes).
