Why is my master cylinder leaking on my 87 Dakota?
Over the weekend I installed a new master cylinder and rear wheel cylinders on my 87 Dakota, trying to remedy a slowly sinking pedal while applying light to moderate pressure, like at a stop light. There was no loss of fluid, so I figured it was the MC. It was time to replace the shoes, so I did it all at once.

What causes a Jeep Cherokee engine to overheat?
There are several belts that may cause overheating just by being loose or worn out. Similarly, hoses can deteriorate or become loose. Belts like the serpentine belt may wear out. When it wears out, your water pump will not be able to do its job if water cannot be pumped in to cool the engine and radiator.
What causes a fluid leak in a cylnder?
But sometimes a leak at the vacuum booster input seal and/or pushrod misalignment can cause a fluid leak, so a closer inspection is needed to determine the cause. This seems to indicate that the brake vacuum booster could be causing the leak, but I don’t see how and that is why I am posting this.
