Doin the restore on the 71 and im putting my brake system back together. The booster looks to be ORIGINAL, along with the master cylinder. The MC may have been replaced but its hard to tell. The Booster is definetly OG.

Should i replace these? The brakes worked great when i took them off the truck. Just wanted to get some opinions.

If they are possibly original....replace em'. Why build something nice that you can't stop??

IMO

It doesn`t take long for a booster or m/c to look old.They may not be that old.But,if this is a restoration I`d go ahead and change to have it all fresh.It`s not a whole heap of money to do.Also,with brakes,I go the thorough route unless in a pinch.With hydraulics it`s best to change cylinders at the same time to avoid a weakness.

I'm going to go the other direction on this one. With the poor luck I've had and seen with parts store replacement parts like master cylinders, I think if it worked fine before.....I'd keep it! I've seen so many "new" and "rebuilt" MCs be bad right out of the box over the years. Just a thought.

I would replace everything with new parts and not go cheap for sure cheaper is not always better..Do it once perfect.

Next question would be the place to buy.. I have all the options of Napa, Schucks, Olympic, and carquest. Where do i want to get em from?

REPLACE at least the master cylider if i had brake fuild in it before and it sat with none in it for a while the seals are going to be ruined why chace it when you can get a new mc at the parts store for 14 buxs i installed one about 2 years ago was anew mc from advance auto parts this was a new unit not rebuilt and it is till working fine

Id say replace the M/C and the wheel cylinders at the very least. If the Booster goes out it will still stop itll just take a bit more effort. Good luck.
