Brake Help
Hi
getting all my parts together for new brakes on my 85 GSL-Se, but I dont know what part this is in this picture (circled).
thanks
ok, so i found the FSM (thanks fox) and it appears to be the differential proportioning valve.
called parts store, they dont have anything like that.

#1 - Welcome aboard! #2 - that's a very clean SE engine bay! #3 - the distribution block stays put when you change the Brake Master Cylinder - why are you trying to replace it?
There's no need to replace that block unless it's cracked, heavily corroded, or leaking and can't be fixed. In truth, the lines there are never disconnected, so should never come into play, and there's no proportioning function to that block - it's only there to break the one line into several so that each wheel gets equal line pressure. Depending on how you're tackling your brakes, you may want to spend some time identifying the problems you have before just replacing parts. Typically, you'll find that brake calipers will leak from the pistons when they need to be rebuilt. A Master Cylinder will just stop braking (*as the fluid is bypassing the internal piston) and can be rebuilt with either a new piston inserted from inside the vehicle at the firewall (IIRC...) or by replacing the Master Cylinder as a complete assembly - your best, most reliable solution.
The rear brake calipers will need some ingenuity to rebuild fully, as the parking brake mechanism can be hard to disassemble if you don't know how it's put together. Aside from that, the entire braking system is straight-forward. Post back with your symptoms, and good luck,

#3 - brakes do not work - pedal travels to floor and i get nothing. figure i would just replace everything brake related while i was at it and draining fluids. however if this part in question has no other function than to divert fluids i see no need to change. Have new MC, brake lines and speed bleeders ready to go, will be adding calipers and pads to cover everything (while i dont see any leaks- just figured i'd do the messy work once and be done).
