Re: [Peugeot-L] 84 505 STI: some brake questions / response

Peat,

        I'm not sure what you mean when you refer to the new valve "piston length" being "pushed all the way in." The end of the new cylinder/valve (that is machined and is clearly the point of adjustment) that I bought protrudes out of the new cylinder a tiny bit and is flush with the end of the little rubber cap. I tried to push it in with my thumb, but it seemed quite reluctant to travel. I haven't pulled the old one yet, but when I do I will break loose the adjuster making sure to keep it exactly where it is now.

        So I assume, from what you are saying that it is okay to drive to, at least my friend's welding shop (where they have a drive up lift)? I am curious how an improperly adjusted proportioning valve could affect the front brakes though, and cause them to lock. Thank you for the response.
