Went up to use the TN this weekend and noticed fluid on the right side of the drivers platform. Upon closer investigation, it appears the rear seal on the right brake plunger has given it up as fluid is leaking when the pedal is depressed.
Can anyone give me advice/direction on fixing this? Is the rear seal the culprit? I'm hoping I don't have to pull the dash apart to get to this, as when I pull the rubber boot back, it looks like there is a retaining ring keeping the internal components intact. I'm hoping the bad seal is the rear seal and located just behind this, but not sure.
Looking at the on-line parts diagram, it looks like I may have to replace the entire hydraulic pump assy. - hopefully not.
Any guesses on why this seal went bad on a TN75 with less than 200 hours on it? Maybe this is normal - but doesn't seem like a part that should go bad.
If I do get the seal replaced, will I also need to bleed the brakes?
Brakes are currently working OK, except for the leak.
