I have a 1992 ford f150 4x4 I was going to school this morning everything was fine, coming home my break pedal would be stiff like normal in some areas and the other time the break pedal would go all the way to the floor with little to no resistance. Any Ideas.

master cylinder or wheel/caliper cylinder going bad.

leak of brake fluid from rusty lines.

flex lines may be bad on the inside and giving way.

best of luck

iv checked all the lines no wet spots, iv checked each wheel no stains. me and my dad have come to the conclusion either master cylinder or brake booster. so we said screw it buy both hope it fixes the problems.

tks for the points
