Soft Brake Pedal Diagnosis
A consistently soft brake pedal indicates a problem in the hydraulic brake system, often due to air in the lines, a fluid leak, or a failing master cylinder. This reduces braking performance and poses a safety risk.
Diagnosis Details
Possible Causes
Air in the brake lines (contaminated fluid or improper bleeding)
Brake fluid leak (at calipers, wheel cylinders, or lines)
