What Causes a Clutch Master Cylinder To Fail

Yes, you can drive with a bad clutch master cylinder, but it depends on the level of the damage and the distance you intend to cover. Basically, if the clutch master cylinder were to fail, it could lead to a few different issues.

One of these problems is that you would have difficulty disengaging your transmission from gear because the piston in the unit won’t depressurize as needed when trying to release pressure on the clutch pedal.

Your car will also jerk and hesitate when you take your foot off the clutch, and it could make engine braking difficult.

Perhaps the most severe issue that can arise from a bad master cylinder is that of fluid leakage. This will cause transmission noises while driving and possibly even create an unsafe situation on highways as you would not be able to shift gears at all in this event.

Now, if you must drive with a bad clutch master cylinder, there are some tips that will help make your ride smoother, which include:

  • Make sure you refill your reservoir often
  • If you have an automatic transmission, be sure to use low gears during acceleration
