Aftermarket MBC
My master brake cylinder to my '87 daily driver needs rebuilt or replaced. I am leaking a reservoir full in two days time. My first inclination is to go with the OE rebuild kit avaialble on e-Bay for about $85 I think. But, then I read that if there is any corrosion in the MBC body that it should be entirely replaced and I won't know that until I pull it all loose. Are there any good brands available thru NAPA or Car Quest etc. that are reliable and a better value than shelling out around 200 clams for Nissan? This will be my first MBC rebuild but, I'm not too worried about that. Thanks in advance.Everything is Meaningless. -

Rebuilt is hit or miss like anything, sometimes they rebuild corroded cores too by honing them out a little… best thing to do is crack it open first and then decide, I'm guessing rebuilding would be fine -

The Nissan rebuild kit is NOT $200. Open it up and decide. Rebuilding them is cake. Just make sure to have a few cans of brake clean and a pipe brush to clean out the bore to inspect for scoring/corrosion. Most of the time the lip seals on the pistons wear out and leak.

One more question. I looked in the FSM and in the Haynes and neither manual mentions how to remove the reservoir. Does it simply pry out? Thanks.Everything is Meaningless. -

Yeah, it pops out.
I can't find it now but, i posted photos awhile ago of the rebuilt BMC i got from NAPA.
It was a oem Nissan core.
