I recently rebuilt the entire brake system on my ‘46. New master cylinder, all new wheel cylinders, new brake shoes, and all new brake lines and hoses. Bought all the parts from one of the major vendors.

About 90 days out, my new master cylinder failed. The vendor was very good about it and provided a replacement. Now, about 3 months later, my right rear wheel cylinder is leaking!! UGH!!

Is this common? Are the new replacement brake parts that inferior….or have I just had bad luck?
