Comments about Carquest Wearever Master Cylinder - New:

I bought this part because it was new and not rebuilt. The part is a little bulkier and heavier than stock. I also does not look like a stock unit as it has a bolt on top instead of a bail wire like the stock unit. This master cylinder works just like a master cylinder should, it was easy to bench bleed and it mounted just like it should on the studs. As long as you are not after a show piece this unit should work better than the rebuilt unit. I will buy this unit again when the need will arise because it seems like a decent value.

      Hi 82yota! Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.

    Does this Cardone 13-1505 master cylinder have built-in Residual Pressure Valves.
    If it does, what are the pressures?

    Is this master cylinder designed so my front or rear brakes are connected to a specific Port?
