Re: Renault rx4 brake problem
I'll check later. Hissing while pedal is pressed, or constantly?
Listen for a constant hiss whilst the engine is idling.
Once the servo is charged - stop the engine and each time you should hear a genle hiss each time the pedal is depressed. It usually stops after 3- 5 presses until the servo is empty of vacuum.
