Brake problems

On my 86 I have had to add brake fluid two times in the last two months. I have checked all the wheel cylinders checked the lines and have not figured out where I am losing fluid at. Has anyone else had this problem?

Check to see if fluid is leaking from the master cylinder into the brake booster.

What is the best way to check that? I would guess the MS would have to be removed.

What he said was that there's a gasket between the MC and booster, clean that area good with brake clean, re-fill, and drive it for awhile, checking often to see where it's leaking.And with the engine off, step on the brake peddle a couples of times, to see/find the leak. It could be leaking on the inside of the cab, check the carpet on the driver's side by the peddles

First, you need to create an account at an online picture hosting site. I really like photobucket.com, as do others. It is free, so it won't cost anything but a few minutes of your time to create an account. Upload your photos to that site and then just copy and paste the IMG code into the body of the message. The IMG code is listed below the picture after you upload, so it is really easy.

I found the problem, where the two line come from the front of the truck they go into some type of splitter/valve???. the fluid is coming from there. Anyone know what this is?

Its the LSPV. Any suggestions on replacing it with a rebuilt or put a splitter at the MC?
