I forgot to get back to you on those shields for the PBR twin piston Mustang/Corvette calipers.They definately work as I haven't boiled my fluid...

Track Wisdom

"Fluid fade... happens when the temperature of the caliper cylinder (or the piston) reaches the boiling point of the brake fluid and tiny bubbles of compressible gas form in and are diffused through the previously incompressible brake fluid. The pedal then goes to the floor, giving rise to frantic pumping of both the brake pedal and the driver's heart[...] Basically, if the pedal goes all soft and horrible you [...] have boiled the brake fluid. The only cure is to either upgrade the fluid or keep it cooler. This can be achieved either by increasing the cooling to the caliper or by insulating the caliper pistons."

-- Carroll Smith, Engineer to Win

How do brake heat shields reduce brake maintenance?

Our brake heat shields help to reduce your maintenance time and effort in a number of ways:
  • Brake fluid is protected from heat cycling with the use of our heat shields. Heat cycling causes a brake fluid to degrade over time, in extreme cases (boiling) it can be ruined very quickly. Hard Brakes heat shields allow you to go longer between intervals for flushing and/or changing brake fluid.
  • Brake caliper piston seals and boots are susceptible to excess heat, which can cause them to melt and eventually become brittle and cracked. When this happens to caliper seals it can cause loss of pressure and require an extensive caliper rebuild. When the piston boots become worn they can allow debris to enter the piston chamber which can cause a seized piston and severe loss of braking. The result is another caliper rebuild, if you are lucky, or a complete replacement.

Our heat shields are not as glamorous as a carbon fiber wing or a shiny chrome air intake system, but they do help to provide real protection for the most important part of your car, the brakes. In addition to saving time and money on the maintenance of the braking system, our heat shields also help prevent expensive off-road mishaps that can severely damage the rest of your car.
