Rear Brakes
For those of you who want to know. The 84 Mazda B2000 rear brakes have only 2 wheel cylinders. One on each side. The one on the drivers side has a brake line that goes in and one that goes out and over to the passenger side. The only bleeder is on the passenger side. Anyone wanting to upgrade to get rid of 4 wheel cylinders should seriously look at the middle model B series trucks. It is a lot cheaper to rebuild or replace 2 wheel cylinders rather that 4, not to mention availability. Hope this helps at least one of our members, Charles

Upgrade?
Thanks for the info, Charles--but there must be a reason our repu's came with four rear wheel cylinders...? Sure, the newer setup is simpler and easier to fix and bleed, but what might the benefits be of the original pain-in-the-ass setup? There must've been a reason they built 'em that way...

I think the old Couriers from the same time period as our REPUs had two wheel cylinders on each side in front. I'm not sure about the back. There was a reason. What is the payload capacity of the B series pickups? I bet it's lower than the REPU. Only larger heavier duty trucks had dual wheel cylinders, at least back in the day. Maybe brake tech has come a long way since then?

Hopefully...
...brake tech., and not just make-it-cheaper tech! Sad to say, but all too often that seems to be the case... perhaps justified by not only lesser capacity, but lesser performance stats. in general? Any case, nice that they went heavy-duty on our trucks!

Assuming that you can get the parts, the cost/work involved isn't worth the effort of conversion. I figured the double cyl. bit was to equalize the wear all over the shoes, as well as make a more even contact with the drum. A better system, but more complex for the factory to assemble...and bean counters rule the auto industry!
