Is it easy? Mines leaking. Would it also be ok to get a remanufactured one from Napa cause a new one is pretty pricey?

It'* not a tough job to actually swapping it out. The work is before and after the job...

Make sure to bench bleed the master cylinder before you mount it in the car. There'* most likely a procedure included in the literature that comes with it.

Then, after it'* mounted, bleed each wheel...starting with the wheel furthest from the master cylinder first.

yea i did mine with basic hand tools in about an hour
