Fellas thanks so much for putting up with our inquiries and more
specifically mine. Thanks for so generously sharing your knowledge. I have
the small car disc upgrade Front and back. I upgraded because I Do a lot of
mountain driving and when I originally got the van it was a death trap.
brakes suspension bushings were all in poor condition it was kinda
terrifying driving. I’m honestly not that impressed with the disc upgrade.
Definitely less brake fade but the wear on the rear pads was horrendous..
One side the pad was untouched the other side was totally warn. I almost
wanna go back to drums that are properly adjusted. Dennis is there anyway
to adjust the rears so that doesn’t happen or is that just what I signed up
for? I wonder if the new Burley Rear disc upgrade is any better? Not that
I’m dropping another g on brake upgrades just curious. Thanks again and
happy Mother’s Day to all the mothers. Peace Tom
