Dodge Grand Caravan brake hydraulic failure with no pedal resistance until floor on Dodge Grand Caravan

Some Dodge Grand Caravan owners report experiencing brake hydraulic failure characterized by a lack of pedal resistance until the pedal reaches the floor. This issue may stem from rubber line failure, where cracked or expanded rubber brake lines absorb hydraulic pressure instead of transmitting it to the calipers, resulting in a soft or spongy pedal. Additionally, some owners have identified brake fluid leaks as a potential cause, which allows air to enter the system and further contributes to the soft pedal feel. Problems with the ABS Hydraulic Control Unit (HCU) can also affect braking performance by disrupting the pressure differential to the rear wheels, leading to diminished pedal resistance. Furthermore, even after replacing the master cylinder and bleeding the brakes, some owners notice that the pedal remains soft and travels further, indicating ongoing hydraulic issues. It is vital for owners experiencing these problems to seek professional assistance promptly to diagnose and resolve the underlying issues, ensuring the safety of the vehicle and its occupants.
