All,
I'm collecting parts to upgrade the front brakes of my '83 CGT to '87 4kq
specs. I have the calipers and pads, and I also have the 16V Scirocco
rotors (same bolt pattern as my hubs and wheels, but 256mm instead of
229mm).
The car is currently at the shop getting new bushings in the front end; I'll
swap the brake parts in when it comes back.
But I do have a question before diving in:
The calipers include just the piston portion; they do NOT include the
bracket or carrier that wraps around the outboard side of it. If you've
done the swap, or if you've recently done brake work, you'll know what I'm
talking about.
Does anybody (Huw? Alan?) know whether I will need to replace this with the
corresponding piece from an '87, or did you just drop the shiny new caliper
into place?
I'm assuming that a light coating of anti-seize on the sliding parts of the
caliper -- where it rides on the bolts that hold it to the upright -- will
help the floating caliper float, rather than stick (though I'll take GREAT
pains to make sure none of it gets on the threads). Yes? No? Better
ideas?
Finally: Are there any other parts I should try to locate before I pull the
car apart? I'm familiar with stock braking systems in general and with this
one in particular, but I've never done this update/upgrade before.
I succumbed to TRS-itis* in two areas: a) I bought the ATE Super Discs, or
whatever they're called -- the ones with the groove that looks like the Atom
Ant logo. Hey, they were on the '93 when I bought it and they look kewl
there, they'll look TWICE as kewl on the '83 with its open Konig wheels.
And b), I went with Mintex Red Box pads -- I've used MetalMasters since the
1980s on pretty much every car I've owned since then, so my feet are used to
the cold-stop characteristics (and I lived in California till a few months
ago, where "cold" means under 70 degreees F). A full report will follow
assembly and testing.
(* TRS, in case it's not on the Master Acronym List, stands for Trick
Racing, uh, Stuff. The "uh" and hestitation is important. :-)
