Just before the Canada trip at the end of July, I
replaced the front rotors (Brembo solids, not
drilled/slotted) and pads on the '72 E. They were
fine on the trip (about 1800 mi.) but just recently
started squealing at low speed, slow stops.
Pads/rotors have maybe 2000 - 2200 mi. on them at this
point. Any suggestions on curing?
Also, starting to think about winter projects. Is it
worth changing the old flexible brake lines to
stainless steel braided?

I had the same problem with the stock brakes, sometimes they woudl squeal in
a highly enmbarassing attention attracting manner… as if my loud exhaust
isn’t enough… never figured out why… coulnd’t find a pattern like
temperature, pressure, etc…
Brake lines ? the ss braided ones are so cheap, it’s not even worth not
doing it. Less chance of one bursting, no risk of fluid being trapped and
draging the brakes…

Pascal’s comment has me thinking about exhaust sound levels.
my 62 has a stock exhaust and although I really like the tone, I would prefer
a little more volume. Anyone running a stock type exhaust without either the
primary muffler or the resonators?
No, but I have a Falcon Stainless Steel system – stock
configuration – and I find it makes quite a loud sound.
Pleasant, but not so great for long highway trips. You could
try a stainless system. I have had it about 18 years and it’s still
like new, that SS is really the only way to go for a long term
exhaust system.

Scott, I ran with only the resonators, could only stand it for
three days, sounded fine at idle but accelerating it was too loud
but at 2500RPM it would start this weird harmonic howling scream, had 18"
straight through glasspacks put in place of the muffler’s and it sounds very
nice, had a nice hum at 3000RPM
then went to Webers and it got quieter, makes no sense to me
because it sounds the same at other speeds, Manuel
Squeal is usually just brake dust. Take out the pads, wash everything down
with brake parts cleaner. If the pads are glazed, either rough them up with
sandpaper or replace. That should do it.

Mike,
As usual, thanks for a straightforward response with a
simple solution. Still trying to figure out what
exhaust resonators have to do with squealing brake
pads.

“Less chance of bursting, perhaps, but there’s a standard rubber hose under
the braid…so the line can still collapse with age.”
To which Jerry replied:
“Hmmm… I believe mine have teflon hose inside…”
As indeed do those I fitted to my bike and those sitting in the garage
waiting to be installed on the E. These are Goodridge (which, because I
purchased them in the UK are also TUV approved) and are most definitely not
rubber.
However, I have covered mine with black heat shrinkable sleeving because I
don’t like the appearance of the stainless braid and it is a real b_gg_r to
clean, not that I actually do much in the way of cleaning (covered the ones
on the bike in heat shrinkable sleeving too, as otherwise it has a tendency
to file off part of the aluminium front forks…).

No, But I have heard straight pipes with just resonators; it is LOUD.
There is also a “big bore” stainless system from one of the vendors.

I wrestled with this for months. My last set of brakes squealed like a
banshee. Highly embarrassing, especially in parking garages where the
sound reverberated for 10 seconds. I tried repeated cleanings,
different brands of anti-squeal goop on the backs of the pads, and tried
a suggested from a lister to bevel the corners of the pads. Nothing
worked. I’ve always wondered whether drilled/vented rotors would help
with this issue, but never got around to trying it.
For other reasons, I had to install a new set of rotors and pads, and
for now the noise is gone. My fingers are crossed, but I fear it will
one day return. The only bright side was that it only seemed to be
really horrible when they were dead cold. After 10-15 minutes of
driving, the sound would always go away.

I had replaced the front calipers with rebuilt calipers on my 240Z a few
months ago and almost immediately they started squealing on every stop.
I knew that the rotors were worn as I could feel a definite ridge on the
outside where the pads don’t touch.
I finally replaced the rotors a few weeks ago and magically the squeal
went away too.
I think it is a combination of glazed rotors and pads that causes the
squeal.
Anyone try just buffing the rotor surface with some #400 wet or dry
paper to see if that makes it go away?
When I put the e-type back together, the rotors looked very good, just
rusty. I bead blasted them and completely rebuilt the calipers myself
and have never had any problems or noise with them.
Steve,
On the late style front or rear calipers, I like to coat the edge of each
piston (where they make contact with the brake pad) with a very thin coating
of liquid gasket maker or silicone sealant. In the case of the latter, let
it set up for about 5 minutes before putting everything in position and
buttoning up. I have never experienced squeal after such
treatment…non-Jaguar cars included.
Regards,
Stefan

FWIW, when I was a young apprentice mechanic, one of the old-timers told me
this trick for eliminating brake squeal. He would drill several tiny holes
in the brake pads and place a piece of mechanical pencil lead (graphite)
into the holes. Apparently the small amount of lubrication solved the
problem. I’ve never tried this myself.
