| Service Brakes problems |
The vehicle's rear brake lines (both left rear and right rear) had ballooning present. The issue was initially identified by an independent mechanic during brake pad and rotor replacement on all four wheels. The ballooning was subsequently confirmed during an inspection by a Subaru dealership technician. This issue posed a safety risk, as the compromised brake lines could rupture under braking pressure, potentially resulting in reduced or complete loss of braking ability and increasing the risk of a crash. To safely operate the vehicle, replacement of the rear brake lines was required. Per the dealership’s recommendation, the front brake lines were also replaced, as they advised that if the brake lines were from the same batch, there was a high likelihood of similar ballooning occurring in the front brake lines. No warning lamps illuminated.
