  Q: How to remove and install a power brake booster unit?

  A: In all probability, you will have to call for periodic inspection of the vacuum hose and the case as a condition for satisfying the power brake booster unit's needs. For this reason, whenever there is a problem it is necessary to buy a new or factory rebuilt unit since one has to utilize special tools in order to disassemble the power unit. First, take out the nuts that hold together master cylinder and booster in the engine compartment taking care not to bend or twist any of the Brake Lines so as not damage them or cause leakages; after that disconnect vacuum hose from power brake booster by removing clip which connects power brake push rod at top of passenger compartment's pedal brake on floor then pull away from firewall until clear from engine bay. Thereafter, proceed with unfastening nuts connecting booster with fire wall carefully taking away this unit free from firewall through engine bay. If you need remove bolts holding it to stop your vehicle- place new one in right position replacing glued nuts before locking brake pedal again; install vacuum hose with master cylinder; finally test its working before moving car into regular service mode.
