I put a new 19mm master cylinder from PMB on my car within the last two years.
The pedal had been getting a little more travel in it over the past week or two. Yesterday at the Autox the pedal got enough travel that it tripped the warning light on. Does this point to a failed master cylinder? If I pump the pedal it will build pressure and reduce travel. after this is done it doesn't seem to drift to the floor with continued pressure. I bought from PMB because I learned form Eric that the ones you by at FLAPS don't have the correct material in the seals and that a new one should last years. |

Discounting any external leakage, increased pedal travel during braking usually indicates an internal leak in the MC.
However, increased pedal travel during heavy braking (autoX use) usually points to boiling fluid and thus increasing pedal travel and softness. Sherwood |
