While driving the other day, all was fine. Suddenly the pedal goes to the floor! I pull over using the hand brake. I fool around in a open parking lot and the problem persist momentarily then suddenly dissappears. Now the brakes seem fine.
After limping home (with no more problems) I can see no obvious issues (i.e. plenty of brake fluid, no leaks or wetness anywhere including the m/c). Although, I am probably over due in replacing the brake fluid. Also, when I say the pedal went to the floor, it wasn't like I was stepping on air, but my braking power probably went down to about 25%. Clearly it is time for some brake work, but how much and where to start? Is it possible for the m/c to fail intermittently? signed lucky |

Hmmm interesting and scary (IMG:style_emoticons/default/ohmy.gif) puzzle.....
1) Pedal went to the floor just once and it works now and before. 2) The handbrake was able to actuate the inner piston on at least one rear caliper. 3) You're overdue for a fluid change. 4) No obvious leaks I have two guesses: 1) Some crud got into a seal in the MC. This allowed the fluid to bypass and caused the pedal to go to the floor. The crud cleared and now the system works again. Could also have happened with just a bad seal that is on its way out. 2) There really is a leak and you just didn't find it. I don't like this answer that much since the leak would have to have been temporary since the brakes work now.... I'm betting that MC is ready for a good reconnoiter. |
