Re: 1990 allante brake booster
There is no booster per SE. It has an electric hydraulic booster pump. Each time the car is started this pump activates to raise the pressure in the system. That pump is activated electrically thru a relay mounted in behind the radiator overflow tank on the inner fender edge. That relay can fail. That pump is shared with late 80's Chrysler rear wheel drive cars. You must swap over the wiring plug to make it work. Have you read the tutorial on www.allantesource.com to confirm what's wrong?
