Buick Rendezvous brakes not functioning despite new brake line installation on Buick Rendezvous

Some Buick Rendezvous owners report experiencing brake issues even after installing new brake lines, such as a soft brake pedal that may indicate a brake fluid leak, allowing air to enter the system and resulting in a spongy feel. Additionally, some report a pulsating brake pedal, which could be due to warped or unevenly worn brake rotors. Owners may also notice that the ABS light is illuminated, signaling a malfunction in the anti-lock braking system and potentially leading to brake failure if the BRAKE light is also on. Furthermore, a firm brake pedal that subsequently goes to the floor could suggest problems with a leaking master cylinder. It is advisable for owners facing these issues to seek a thorough inspection to identify the root cause of the braking problems.
