Thanks Jon.
The wheel-tire cost is something to consider for sure
and something I tend to forget about. How convenient. ha ha. ;)
At this point, a local vendor has what I think are new,
not remanufactured, newer style calipers. I installed a pair
on my '88 That bus has better braking than my '81
and what I'd consider to be "normal" by modern standards.
A *very* kind fellow Vanagon enthusiast set me up with known good
newer style steering knuckles, calipers, lower arms
etc. I'll install those along with the GW progressive springs
I just received. For the foreseeable future, I'll keep
the older brakes, in part because I want to see how much
better I can make them using well documented info
from this list. It's all been done before, but I'd like to learn
more and improve what's there.
To that end:
- try to find pads that have more "bite" (grab better at first application)
Excessive dusting or accelerated rotor wear are not a concern for me.
- install the silencer shims I found at van-cafe.
These may help the pads wear evenly. The last set wore at an angle
possibly due to lack of these shims?
- install new shoes, shim out lower anchors as needed
- rebuild a spare set of Girling calipers
with new pistons, seals.
A recently replaced failing master cylinder has certainly improved
the brakes.
Neil.
