How to Reduce Thermal Conductivity Of Heat To Brake System Fluid
Feb 17, 2012 2:23:16 PM
There is a identical effective way for car enthusiasts to reduce the brake fluid temperature overall during periods of high performance force, and it involves making material changes to the brake caliper components .
There are several different types of metals that can be used as a connective between brake pads and brake organization fluid, and it is the properties of the metals that will affect the thermal transplant of heat from one to the other .
We are going to review the diverse materials normally used in brake caliper components in this article, and discuss thermal barriers that can be used to further shield heat transfer to a brake systems fluid .
Stock Caliper Metals Used
Stock brake caliper pistons that come from the factory are made from steel as a rule of ovolo. You might find that stainless steel is being used in some high end performance vehicles. additionally, you might besides find performance calipers systems that include a stainless steel heat barrier being used to far insulate a hot brake rotor from its brake line fluid. By using stainless steel steel as an mediator, a driver can efficaciously reduce the total of hotness transfer from diggings to fluid by american samoa much as 50 % .
Ventalated Titanium Caliper Piston
To go one step further, titanium can be used in the manufacture of bracken caliper pistons to maximize thermal estrus transfer retardation. extra properties that make titanium a good choice include its ductile potency and lightweight properties. sometimes, an stallion brake caliper piston is cast in titanium ; other times, piston calipers are merely coated in titanium oxide .
If a driver does not want to purchase a set of high conclusion brake caliper systems that utilize titanium coated piston calipers, they may actually go in and crown tip their brake caliper pistons with titanium to reduce thermal heating system transfer. This method, however, lone results in a partial profit from the use of titanium as a thermal barrier .
Titanium Heat Shields
If bracken calipers are not coated with titanium, then titanium heat shields can besides be use, to “ harbor ” heat from affecting the brake fluid. These heat shields are cut to be approximately the same size as the brake pads themselves, and are used like a shim that fits between the pads and the pistons .
By using titanium thermal heat shields, one can actually reduce the amount of heat transference to the rotor by angstrom much as 50 % .
titanium is a thoroughly choice for use as a heat shield because of its lightweight properties and its resistance to corrosion. typically, a titanium hotness shield will only add 5 ounces of weight unit per rack, so the drawbacks of using them are minimal .
