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 describe a range of brake failures across this 2007 Mustang cluster. The most critical issue is complete loss of brake pressure, where the brake pedal goes to the floor with no resistance at low speeds. One owner at 3 mph in a drive-thru lane lost all braking and had to shift to Park to stop; another at 2,018 miles experienced the same after hitting a bump, requiring the emergency brake to prevent a collision. A dealership service writer confirmed this is a recurring defect on 2004 and 2007 Mustangs and diagnosed master cylinder failure.
Emergency brake problems run throughout the complaints. Several owners report the brake sticking or refusing to release after normal use, leaving their cars held in place on grades or slowing unexpectedly during driving. In cold weather, the e-brake freezes solid. One owner replaced the brake cables at $500 with no improvement.
Brake fluid leakage shows up in multiple reports: fluid weeping from the reservoir cap with persistent moisture buildup, and fluid leaking from the front driver side after going over a bump. One dealer inappropriately installed DOT 4 fluid instead of the DOT 3 specified in the owner's manual.
Caliper and rotor problems include undersized or misfit calipers, brake pad scratching rotors at 25,000 miles, and at least one caliper breaking unexpectedly—a mechanic reported seeing the identical failure on another Mustang, same side and location.
Dealerships have struggled: unable to reproduce failures during inspection, refusing repairs without recurrence, or addressing only secondary issues. Ford has similarly declined to repair some defects, claiming the incidents could not occur as described.

Failure modes owners describe
Emergency/Parking Brake Stuck or Not Releasing
Emergency brake does not release fully or freezes in place. Owners report the brake holding unexpectedly during normal driving, refusing to disengage after use, and in cold weather conditions freezing solid. One owner had to replace brake cables at $500; others report the vehicle remaining held on grades or slowing excessively.
When: Within 10 months of new purchase; recurring; cold weather trigger noted
Symptoms owners cite: Emergency brake does not release fully; Vehicle slows more quickly than normal; Vehicle remains in place on slight grade despite neutral selection; Parking brake freezes in cold weather below freezing; Parking brake fails to hold vehicle on grade (separate issue); E-brake becomes stuck after normal use
Repairs/costs cited: Brake cable replacement cited at $500; one owner replaced cables with no resolution of holding problem
Complete Brake Failure or Loss of Brake Pressure
Brake pedal loses pressure and travels to the floor with no resistance during normal braking. Occurs intermittently; dealers unable to reproduce the problem initially or during inspection. One owner reported this as a recurring defect in 2004 and 2007 Mustangs per dealership service writer. Master cylinder replacement was diagnosed as needed.
When: Early in ownership (2,018 miles on one vehicle; 15,300 miles on another); recurring episodes
Symptoms owners cite: Brake pedal travels to floor without resistance; Complete loss of brake power; Brake failure occurs at low speed (3 mph in drive-thru); Failure after going over bumps or road debris; Emergency brake needed to stop vehicle when pedal fails
Repairs/costs cited: Master cylinder replacement identified as necessary; one vehicle remained unrepaired due to safety concerns
Brake Fluid Leakage or Contamination
Brake fluid leaking from reservoir or cap area; moisture accumulating in fluid reservoir. One owner reported fluid leaking from front driver side area after going over a bump. Another reported continuous moisture buildup despite adequate fluid level. Dealer noted DOT 4 brake fluid used instead of recommended DOT 3 in owner's manual.
When: Early in ownership; 2,018 miles
Symptoms owners cite: Brake fluid leaking from reservoir cap; Moisture accumulating on reservoir; Fluid leaking from front driver side toward engine; Soft brake feel; Moisture returns after wiping
Repairs/costs cited: Dealer did not attempt to replace cap; fluid replacement not performed per reports
Recalls/TSBs owners mention: Dealer used DOT 4 fluid instead of DOT 3 specified in owner's manual
Brake Caliper or Rotor Defects
Calipers undersized or incorrectly fitted; rotors scratched by brake pads; calipers breaking unexpectedly. One mechanic identified calipers as not correct size and not wide enough. Rear passenger side brake scratching rotor at 25,000 miles. One driver-side rear caliper broke; mechanic reported seeing the same defect on another vehicle, same side and position.
When: 25,000 miles for rotor scratching; caliper breakage unspecified mileage
Symptoms owners cite: Brake pads scratching rotor; Calipers undersized or incorrect width; Caliper structural failure; Rear passenger side rotor damage at low mileage
Repairs/costs cited: Calipers, rotors, and pads identified as needing replacement; caliper breakage required caliper replacement
Throttle Control and Brake Interaction Issues
Engine RPM spikes unexpectedly when shifting from Drive to Park without driver input on accelerator. One owner reported RPM jumping from 600 to 6,000 RPM instantly. Another reported throttle stuck open with no brakes available and engine running at 7,000–8,000 RPM. Dealership suspected fly-by-wire, throttle body, or control flow issues; Ford denied the incidents were possible.
When: After freeway driving into rest stop; one incident at unspecified time
Symptoms owners cite: Sudden RPM increase (600 to 6000 RPM) when shifting to Park; Throttle stuck open; No brakes available during throttle event; Engine revving to 7,000–8,000 RPM uncontrollably
Repairs/costs cited: No repairs performed; dealership and Ford refused to repair, citing inability to reproduce
Recalls/TSBs owners mention: Ford stated incident could not have happened as described; refused repair without recurrence
Electronic Brake Light Shutdown
Opening the vehicle door causes the electronic system and brake lights to shut down. System resumes operation after a few minutes. Dealer replaced instrument panel and modules without correcting the issue.
When: At 6,700 miles; failure noticed at 40 mph
Symptoms owners cite: Electronic system shuts down when door opened; Brake lights shut down with electronic system; System recovers after few minutes
Repairs/costs cited: Instrument panel and modules replaced; defect persisted
Recalls/TSBs owners mention: Dealer attributed to rear axle assembly problem

How serious is the brakes problem on the 2007 Ford Mustang?
It's a meaningful issue. 14 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $450.
At what mileage does the brakes typically fail?
Across the 14 complaints that reported odometer mileage, most brakes failures cluster between 12,752 and 55,000 miles, with the median around 28,000. A quarter of owners report trouble before 12,752; a quarter make it past 55,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to brakes?
No active recalls currently cover brakes issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
