I stopped kind of hard and heard a loud pop and right away my break pedal went to the floor. it will still stop but it goes all the way down??? What should I do?
How can I tell if my break line is broken?? on 1991 Buick Riviera
If your brake line broke somewhere you will find brake fluid pouring out somewhere. Suspect this may be the master cylinder that gave out.
or possibly a brake caliper over extended inself. look for a large amount of fluid.
