Soft Brake Pedal During Hard Braking - 2020 Jeep Wrangler
A soft brake pedal during hard braking indicates a potential issue with the brake hydraulic system, such as air in the lines, a failing master cylinder, or a brake fluid leak. This condition reduces braking performance and can lead to brake failure, especially under heavy braking.
Diagnosis Details
Possible Causes
Air in the brake lines (contaminated or low brake fluid)
Failing master cylinder (internal bypass or worn seals)
Brake fluid leak (at calipers, wheel cylinders, or lines)
