Well, as the subject says, I have a '97 E36 320i, and since I drive it hard,
my brakes always get smoked after such driving, but the real problem is that
they stop braking efficiently, so sometimes it's even dangerous. A friend of
mine advises teflon-based brake pipes (where the fluid is) for a low-cost
solution (like because they don't get affected by heat and thus don't expand
and lose their pressure), and for high-cost solution a complete change of
brakes and putting the M3 brake system.
What do you say?
Better brake lines won't reduce fade (due to boiling brake fluid).
1) ensure that the brake cooling ducts are open and actually cool
the brake rotors.
2) put on ceramic pads
3) consider cross-drilled rotors.
No, the reason you have brake fade is either a) the type of pads you are
using or 2) the fluid is too old and has water in it.
My suggestion would be to skip the fancy brake lines and get a set of
good combo street/track performance pads and flush the brake fluid.
The stainless steel jacketed (Teflon liner) brake lines are more for
preventing one of the lines from failing during racing by being hot by
some track debris than they are for improved braking. People will try
to convince you that they will make the brakes more responsive because
they don't expand as much under pressure, but the stock lines don't do
that either, at least not if they are in decent shape.
well, there already are ducts for cooling the brakes, and wheels are 17" so
I might consider putting a 325 brakes, or change the fluid as Malt said. But
there shouldn't be a problem with brake pads, since they're new, I bought
them and installed last week, it's Lockheed. And, when I drive hard and
brake hard, they start smoking white smoke and smell bad, but also they lose
their efficiency and I have to press them even harder to stop.
BINGO! I think you have just diagnosed your own problem. Whenever
troubleshooting any kind of problem, be it automotive or electric,
electronic, whatever, always suspect the MRFWU.
If you just recently replaced the pads and now they are smoking (sign of
excess heat) and do not seem to stop the car fast enough, wouldn't you
suspect the new pads first?
Or was the problem there prior to the pad change last week?
MRFWU = Most Recently F***ed With Unit(s)
Brakes brake poorly whenever the car is driven hard. It's got nothing to do
with new pads, he braked poorly with old pads as well as with new ones.
Thus, I believe the problem generally is in - poor brake system which was
not designed for hard driving, in my opinion. After all, it is a 320i
limousine, not an M3 :-)
It's probably one of the "flaws", so now I must consider improving the
Maybe the best thing to do would be to buy new drilled front discs?
Your problem could be a simple as lousy pad choice. Try a set of
Repco/Axxis/PBR Metalmasters for a more aggressive street pad. I've
used them for years on OEM rotors and been quite satisfied. They're a
bit marginal on track, but for street use, I love 'em.
The other thing that occurs to me is that you may not have properly
bedded in your pads. If you glazed them, they're trashed already. If
you switch to Metalmasters, be *sure* to follow the procedures for
bedding them in.
(Been there; done that)
where I live there are no "metalmasters" etc., but only the most common
brands such as brembo, lockheed, etc.
might be, but I still think that problem is in poor cooling which may be
solved by either drilled discs or change of complete system :-(
because, pads I had before had shown similar behavior when pushed hard
