Hi All,
I converted my 427 Tri-Power from manual brakes to servo assist about 5 years ago. The kit included a new master cylinder and new servo unit.
The problem I'm having is unpredictable. The brakes can work fine for a few days then the pedal pressure can go way up as though the servo wasn't working. This can last for a while then back to normal.
Any advice would be very helpful.
Thanks, Peter
