Description of the problem | Brake booster had a vacuum leak. My car was outside the existing vin list for recalls and/or "customer satisfaction program". Vacuum leak and stiff pedal was most evident at low speeds (near idle and at high vacuum conditions) ford would not replace my booster. I replaced it myself and found that the oem booster had rusted, where the master cylinder seal (square cross-section o-ring) met, causing the leak and poor braking at low speeds. Master cylinder was in good condition, with no apparent leak - inside of booster was dry and clean. Replacing both the master cylinder and the booster has cured the problem. Problem was first noticed when parked - if my foot was on the brake, maintaining force, when i turned the ignition off, the vacuum immediately bled off of the brake booster, causing the pedal to rise and stiffen. Inspection of the booster prior to replacement did not give any evidence of an obvious problem (that is, no hissing or leaking sounds were present) the problem became more apparent over time (over the past 18 months) and got to the point where i felt that i did not have sufficient braking power to stop the vehicle at lower speeds - thus, my decision to replace the booster and master cylinder. In the last few weeks, the leak must have been getting worse, because the pedal was getting harder and harder to push down, with pedal effort increasing as the vehicle speed dropped (like approaching a stop sign) i am strong enough to push hard - but a small or frail person encountering this problem may not be able to stop in time. |
