Some Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00. The brake rotors should only be machined if directed by the WSM because one or more of the following conditions are present on the braking surface: scoring, excessive corrosion/rust or pitting, bluing/discoloration and/or heat spots. For additional information, refer to WSM section 206-00.

What stands out
No new NHTSA brakes complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners of 2007 Lincoln MKX vehicles consistently report brake booster failure as a critical safety issue. The symptom pattern is clear: brake pedal becomes hard to depress or goes completely to the floor, requiring extreme force to slow the vehicle or stop it. One owner had to stand on the brake pedal while driving children to school; another reported the car rolling slowly even under maximum braking force. A dealership replaced one booster for $786 out of warranty. A few owners describe stiff pedals from new, while others report failure appearing around 113,000–140,000 miles.
The master cylinder also shows up as a failure point. In one case, a dealer initially dismissed a pedal-to-floor condition as normal until the customer pushed back. Even after replacing the master cylinder, the pedal remained soft, pointing the technician toward the vacuum system as the actual culprit.
One owner experienced an ABS warning light illumination during braking at highway speed (75 mph, 140K miles), though the vehicle did not lose all stopping power in that instance. Another owner describes a total loss of brake pressure—which they call vapor lock—that resulted in a crash.
The common thread is loss of brake assist function, making the vehicle unsafe for families and heavy traffic. Some owners chose to avoid highways out of safety concerns.

Failure modes owners describe
Brake Booster Failure
Brake booster loses effectiveness, causing the brake pedal to become hard to depress, unresponsive, or requiring extreme force to engage brakes. In some cases accompanied by stiff pedal feel and air pressure noises from the booster.
When: Mileage ranges 113,832 to 140,000; some owners report issue from new (2007 purchase). Failure can occur during normal city driving, highway speeds, or while stationary.
Symptoms owners cite: Hard, stiff brake pedal requiring excessive force to depress; Brake pedal slow to respond or hesitant to engage; Vehicle continues to roll slowly even with hard brake pressure; Air pressure noise or hissing/screeching sound from brake system; Engine vibration or near-stall when brakes applied at stop; Brake booster cannot be depressed below certain point without locking feel
Repairs/costs cited: Lincoln dealership replacement cost reported at $786.00 by one owner. Brake light switch replacement also recommended by independent mechanic in one case alongside booster replacement.
Recalls/TSBs owners mention: Owner in narrative #4 contacted manufacturer and was informed their VIN was not included in NHTSA Campaign 19V904000 (Service Brakes, Hydraulic). Manufacturer notified in at least one case (narrative #5) but no TSB or recall activity documented in these narratives.
Master Cylinder Failure
Brake master cylinder loses hydraulic pressure, causing brake pedal to travel all the way to the floor without generating stopping force. Dealer initial misdiagnosis as normal behavior delayed diagnosis.
When: Condition intermittent, recurring over several days before diagnosis and repair.
Symptoms owners cite: Brake pedal goes to floor when depressed while vehicle standing still; No brake pressure or resistance felt at pedal; Condition recurs after initial master cylinder replacement, indicating possible vacuum system involvement
Repairs/costs cited: Master cylinder replaced at dealership. Vacuum system replacement initiated after pedal-to-floor condition persisted post-repair.
Vacuum System Failure (Brake Booster Supply)
Loss of vacuum supply to brake booster, preventing booster from multiplying pedal force. Identified as root cause after master cylinder replacement did not resolve pedal-to-floor issue.
When: Identified during warranty troubleshooting; exact mileage not stated.
Symptoms owners cite: Brake pedal goes to floor after master cylinder replacement; Loss of brake assist function
Repairs/costs cited: Vacuum system replacement in process per dealer.
ABS System Fault
ABS indicator light illuminates randomly during braking, though no actual stopping failure reported in this case.
When: At approximately 140,000 miles while driving 75 mph.
Symptoms owners cite: ABS indicator light illuminates randomly when brake pedal depressed
Repairs/costs cited: No repair performed.
Recalls/TSBs owners mention: Owner spoke with manufacturer; VIN not included in NHTSA Campaign 19V904000 (Service Brakes, Hydraulic).
