    Hey guys,
    for anybody who uses their car for track days, we have Titanium brake caliper heat shields available for most Ferrari (and other applications). One face of the shield is coated with a Ceramic thermal Barrier Coating for added protection.

    Helps keep the heat out of the caliper pistons to prevent brake fluid boil.

    Consider it cheap insurance when you are approaching the first turn at the end of a long straightaway.

    Cheers,
    Eric




    Girodisc Announce Ceramic Thermal Barrier Coated Titanium Heat Shields

    COSTA MESA, CA – May 2005 – Girodisc announces its line of Ceramic Thermal Barrier Coated Titanium Heat Shields for selected vehicles. These Shields are designed to greatly reduce heat transfer into the brake caliper pistons and brake fluid, thereby reducing the chance of fluid boiling and brake system failure.

    The problem of brake fluid boiling is simply traced to heat transferring from the rotors and pads directly into the fluid through the caliper pistons. When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid. This air is compressible of course, and the brake pedal goes to the floor instead of moving the caliper pistons. Production cars tend to suffer from this on track days more as they don't usually have the extensive cooling duct and exotic brake materials as true racing cars.

    The Girodisc solution to help prevent fluid boiling is to use a thin, ceramic barrier coated titanium shield placed between the pad back and the pistons, to keep the braking heat from transferring into the pistons and fluid. The thermal protection from this combination is significant and proven.

    HOW DOES IT WORK?
    Titanium as a material has low thermal conductivity. This means that it is very bad at transferring heat - which is good if you are trying to keep your fluid cool. Titanium has a rate of thermal conductivity that is about 10 times less than that of steel.
    The Girodisc heat shield is also coated with a ceramic thermal barrier on one side. This is the same material used to protect aluminum piston crowns in high boost motors. The Ceramic thermal barrier has a thermal conductivity rate that is 50 times less than steel.

    For cars that are going to see hard or multiple track days, the combination of these materials in one shield is a proven method and cheap protection from brake failure due to fluid boiling.

    To find out more, contact Girodisc at (949) 350-6194 or email info@************. More information is available on the web site: www.************.

    We used to make these out of carbon fiber. It's cheaper and they conduct less heat. You simply get a sheet of solid carbon fiber (a single layer will do), lay your pad over it and trace out the shape. Get your CF snips and cut it out. Insert between the pad and caliper. The resin will get sticky with the high heat but we'd never had any problems other than that. We used it on SCCA ITS and GT1, GT4 cars. We also used them on FF2000 (Formula Continentals) and Formula Atlantics.

    Did you just say "yawn"..?

    You may be familiar with a method to protect the fluid from boil...to many here this may be new and useful info.

    Using carbon is also effective as a heat shield, however once the epoxy bakes out the carbon shim will soon deteriorate. We are using Titanium as a LIFETIME of the car product. Buy it once, use it forever. If somebody such as yourself wants to cut carbon shims with pad changes, more power to you.

    I welcome all information and ideas to be posted. I suggest next time you leave your "yawn" attitude out of the conversation. Not everybody reading this is the racing technology "guru" you must be.

    True I shouldn't have said yawn. But, I think this has been discussed on the forum before. I could be wrong, so I'll appologise and adjust my attitude.


    You are correct that the CF will not last a lifetime.

    While not a "guru" as we're on the subject of better braking I'll include another trick. Elimination of firewall flex. As we all know braided brake lines help decrease braking distances by increasing pedal response and feel (they'll eliminate that "squishiness") by helping eliminate the flex and line bulging/expansion. On older cars this performance increase is even greater as older brake lines are softer than when new. But, did you know that when you stomp on the brakes hard your firewall may also be flexing and in doing so may be adding to this "squishiness" and preventing you from getting 100% from your brake system? You can actually see the flex with the naked eye in some cases.

    On my MR2 Brad Bell racing has come up with a brace (they're also made by other firms for other cars) that will all but eliminate the flex. Flex was reduced from .077 & .072 to .022 measurement. That may not sound like a lot but it makes a lot of difference with brake modulation and being able to control the pedal accurately. I'd think that the older tube frame cars with very simple fire walls would benefit greatly from a bracket such as this.

    No worries, everyone has an off day. Thanks for the post.

    Its likely that every subject has been posted here a few times. But I gotta keep getting the message out to those who might want to know, without knowing what they were looking for.

    The firewall brace is a very nice part. Often times a road car will have a thin guage sheet metal firewall bulkhead to mount the booster/MC assembly with no further support. Your brace goes a long way to keep this area stable and give a much more consistent pedal.

    Cheers-
    Eric

    Has anyone tried the titanium or the rubber coated shims? If so, is the pedal feel still firm or does firmness suffer as a result of using these?

    Worked very well for me. Ti shims w/no coating. Porterfield pads and dot 4 fluid in a '77 euro 308 w/stock brakes. I drove the wee out of it until a deer ran out...
