Comments about Wearever Master Cylinder Master Cylinder - Remanufactured:

It seems that the rubber seals provided to hold the fluid cups - were oversize, I could NOT! get the brake fluid resevoirs on with new seals provided. I was able (after about a/an hour of trying to put on new seals) to use the original seals... PRESTO! brake fluid cups fitted right on (took about a minute). This is a very good master cylinder. I installed it and drove car all day: Do you have any tips on how to use those seals?Original equipment rebuild, fit, and function, PERFECT. The bleed kit provided helped speed the repair along, If I had not had trouble getting cups on this would be rated 5 stars. The included instructions did not include instructions to get core refund(nothing on paper work or maybe I missed it), so I called and was told to take it to a store - very easy, may be this should be printed on order sheet. I also liked how everything was in Computer at store. Core refund was short and sweet. Thanks L.J.
