I have an '87 Turbo with 52,000 original miles on it and it is slightly leaking some brake fluid. It looks to be leaking at the back of the brake master cylinder where it connects to the brake booster. The brakes still function very well but now with a squishy pedal.

Should I presume I am in need of a new brake master cylinder? Otherwise, is there a gasket that goes in between the master cylinder and the booster that might be bad? Or is it a seal in the actual master cylinder thus would need rebuilding or replacement?

I am not super familiar with the availability of options for certain years of Turbo II but I am assuming my Turbo II lacks ABS and an adjustable suspension (no powersteering, no power door locks, cloth seats) thus making the following part what I would need: http://shop.advanceautoparts.com/web...1289061004____

You have answered your own question, expecially at the end.

 

Did this end up being the solution? I have the same issue on my TII

 

yes, its very common.

 

The one thing that confuses me is my manual says that with my turbo model with no ABS, it should have two hydraulic lines coming off it, but the one in my car (which looks original) has three lines, one on each side and one out the bottom.

 

pick up a subaru wrx booster and master cyl if you haven't done this yet i did mine not too long ago it bolts right up and a major difference. not very complicated and they are less expensive and more plentiful then fc boosters.

 

the ABS car has two lines the non ABS cars have three. the listings are confusing, but basically there are only 5 masters.

89-91 turbo.
87-88 ABS without AAS GXL only
87-88 ABS with AAS GXL only
86-88 non ABS with AAS GXL only

and 86-91 no ABS, no AAS. FB02-43-400C

 

Ahh, ok thanks for the info, I ordered the non ABS turbo reman and swapped it out no problems. The reservoir was a little tough to get into the new master cylinder but putting it in a vice and rocking it slowly while pushing down eventually got it. The brake fluid must have been leaking for a while cause it ate away the paint on the booster housing where it was dripping.

 

What do you guys use to clean the brake fluid off of everything? I was thinking brake parts cleaner but it says on the can that it will eat paint and plastic, so I ended up using electronic contact cleaner. Seemed to work ok.
