Hi all,
I recently took delivery of the ECS stage 2 big brake it. I've got a
bunch of questions and I'm hoping for some BTDTs.
1) I have the "big blacks", not the "big reds". As I understand it these
calipers are from the 928 GTS, and are identical to the 993tt calipers,
except that they are configured for trailing (behind the axle) mounting.
The ECS invoice has the cryptic phrase "Calipers do need swapped." I
assume they are talking about the leading/trailing issue. However,
the calipers appear to already be in the correct orientation for
leading-edge mounting. Please see this picture for (at least what
I believe to be) the driver's side caliper:

Please correct me if I am wrong!
BTW, the boxes the calipers came in have the Porsche part number
928 351 423 03.
2) I want to replace the bolts which attach the ECS bracket to the spindle.
Is N 901 740 01 the correct Audi part number?
3) Loc-tite on all the bolts? What torque is recommended for the
caliper to bracket bolts? I assume the bracket to spindle bolts
take the same torque as (hopefully) published in the Bentley.
3) The ECS invoice also says "check caliper hold down bolts to confirm
that length is not too long" -- are they talking about their supplied
bolts (caliper to bracket), or the ones that mount their bracket to
the spindle? I guess I should call them on this one...
4) Is the splash shield retained with the big brake setup? If so, do I
need to modify it?
5) I bought a power bleeder and two liters of ATE super blue. Is two
liters enough? What is the preferred bleeding order -- I am going
to do a complete flush.
6) Besides the adhesive-backed clips that go into the pistons, is there
anything else I should do on the squeal-reducing front?
Thanks in advance for your help, and sorry for putting so many questions
in one message. I have done a few brake jobs, but this is the first time
with non-original parts, so I'm a bit of a newb. Plus I will be borrowing
a garage that's an hour away to do this work, so I really want to get it
right the first time!
