Power brake master and slave who is best 1970 ?

[Bob B.]

Happy Fathers Day all, hope you are enjoying a day with your Vette.
I am doing a on frame restoration of a very nice yellow 70 Convertible, almost a survivor. Both the master and slave power brake units need to be replaced inop/rusted / replaced over the years. Who sells a very good unit and dates them ???
Yeah, I know but I am going to DRIVE this one all the proper dated cores I have found are too far gone rusted
March 28, 1970 build if you have a GOOD rebuildable core power brakes std
THANKS Bob

Bob ,Dewey’s Booster, rebuilds them if you have your original booster. he is good and prices are great he should be listed in driveline. if your master cylinder is original lonestar can resleeve the master and install a rebuild kit.

GM casting number 5460348 master cylinder cores are not that hard to find. You want one with bleeder valves for a 1970. Lonestar can probably supply one already sleeved and rebuilt.

This master cylinder is also reproduced under the GM Restoration Parts Program so it can be had in new condition with all the original markings and features. I think they can also be dated as you wish. The downside, if it bothers you, is that I believe the castings are of Chinese origin. The big difference, though, as far as I'm concerned is that I believe the reproduction castings are grey iron. Originals are malleable/ductile iron, a stronger and better material. However, for a master cylinder it probably really does not matter that much.
