[don t. - 72gmc]

New brake system...front to back...left to right... on a 70 GMC. 4 drums if it matters. Im an old guy, always used Dot-3. Went to my local auto parts store. No plain old Dot-3. For all intents, only synthetics. Didn't buy any. Hope someone can educate me on the new stuff.

Thanks much...Don.
