so i drove my 88 sq this morning she was fine. then in the afternoon i drove her again my brake pedal became stiff after the first stop. then it became regular again so on and so forth. i was wondering if anyone had this happen to better help me pinpoint my problem. shes my daily driver so i need to find problem and fix within a days worth of work hopefully on saturday night or sunday. i checked my lines they seem fine no disconnection by the way. thanks!!
