Depress brake pedal multiple times with engine off. Check for no change in pedal reserve distance. Depress pedal and start engine. If pedal slightly goes down, operation is normal. Start engine and turn off after 1-2 minutes. Depress brake pedal slowly multiple times. If pedal goes down further first time but gradually rises after second or third depression, booster is airtight. Depress brake pedal while engine is running, then stop engine with pedal depressed.

Lincoln Navigator Brake Booster

Lincoln Navigator cars contain the Brake Booster which is of significant influence as it lessens the force that a driver employs while pressing the brake. It enlarges the hydraulic pressure from the master cylinder by employing a vacuum chamber, and this intensifies the force that a driver applies on the brake pedal. There are two main types of boosters used in Navigator vehicles: includes vacuum-operated boosters and hydraulic boosters. Vacuum boosters work on the difference of vacuum pressure existing inside the engine and atmospheric pressure while hydraulic boosters work on fluid pressure to help in the application of brake. These booster are rather dependable but may wear out from time to time and would have to be replaced. Lincoln Navigator boasts of different performance brake boosters and power brake conversion kits to maximize simple as well as effective braking for any car.
