General Maintenance & Repairs - Fenco brake master cylinder

hey everyone I am think my Master cylinder may be bad. Luck for me It has a lifetime warranty. Problem is that it is a LUK brand which autozone (where i bought it) no longer carrys them. They will give me a Fenco brand if I bring mine in. Anyone ever used a fenco Master cylinder?

I've got some Fenco products on my DD truck. Only part I had problems with was the power steering pump, shaft was too large for the pulley.
