LEAKY BRAKES!! ?? What is this \'eye\' for? again, on a 1984 S-10....but probably on others too. Was bleeding the brakes last night and saw some drips coming down from above on the master cylinder. Got to looking and it is coming out of this 'eye' http://community.webshots.com/photo/80502944/105202399vgrQpq http://community.webshots.com/photo/80502944/105202384YcXRCr It appears to be a rubber 'eye'. Why would it leak from there...do I just have to replace that whole dist. block?? Thanks!
