Need more info. 

Is it a Girling servo or one of the aftermarkets? Did you do anything to the master cylinder? Does the pedal return all the way? 

With the Girlings, the M/C pushes a slave piston in the booster that actuates an air/vacuum valve to activate the servo's main piston. If this valve doesn't release for some reason the servo could continue to apply pressure to the wheel cylinders. 

My SWAG with the available data is something wrong with the new servo (IFF you didn't mess with the M/C).

Hi List, 



Looking for some feedback on problem. 



I installed a new Brake Booster on my BJ8..works fine except when I take my 
foot off the brake, there is a 5 or 10 second delay before the brakes 
release entirely. Seems to hangup on both the front and back brakes. 



Thanks for the help.
