Comments about Carquest Wearever Master Cylinder - New:

Casting has a smaller reservoir opening; original debris screens will not go all the way in without modification. This creates a bit of a chore while bleeding the brakes because you tend to have fluid squirt out the top unless the caps are refitted prior to the attempt. Even then, the caps will be wet & tend to drip when refilling is necessary during bleed process. Seems like something the factory messed up on. However it is a new part and replaced the original which was necessary. I'm not sure that a rebuilt original would have been better, time will tell as far as longevity goes. Installed on a 40 year old Datsun Z; I'm sure I'll have another opportunity to replace this as it seems to come up once a decade or so.
