Brake Master Cylinder: Replace it or not?
« on: November 24, 2012, 02:16:56 PM »
I'm in the process of doing a complete refresh on my '91 318is and am hopefully putting together one of my last parts orders. I'm wondering what the consensus is regarding reusing or replacing the brake master cylinder.  I didn't drive the car all that long before tearing it apart to begin repairing/rebuilding, but never had any problems or fluid leakage with the original braking system.  I am installing an UUC front big brake kit and replacing nearly every other component of the braking system (front and rear), with the exception of the hard lines and abs unit.  

I like new components with new fluid, but $300+ for one item is a bit steep if it's unnecessary.  On the other hand, I would rather do it right the first time and save myself the work in the future if it's something I'll have to replace anyways.

I don't know the current mileage as the odometer was nonworking when I purchased the car (I believe 130k plus, but can't remember off the top of my head).

If it makes any difference I will be using the car for daily driving, autox and a handful of track days each year and hope to see forced induction under the hood within a year or two.

Thanks,

Micah

Rock Auto has what appears to be a very complete rebuild kit for $49.95.
