PCCB iron disc replacement

Ever since the disc brake was invented vibration and pulsation caused by thermal expansion has been a major issue giving rise to warped discs - until now?

PFC has released new V3 disc and hat technology. The advanced design features a patented attachment design that uses a retention ring that holds the hat and disc together.

The ring means no need for torque wrenches, and no hassle. The ability to change a disc quickly and efficiently saves time and effort. As well as being convenient, the new V3 technology is much lighter than previous designs, making it easier to put on and pull off, and making the vehicle lighter.

This V3 disc retention method is based on the use of a two-turn retaining ring, which is held in a groove in the hat that overlaps the disc flanges – effectively locking the disc to the hat.

● Exceptional manufacturing standards - Run out less than 0.0254mm, Thickness variation less than 0.00762mm. Surface finishes less than .7 microns.When used in conjunction with Z rated fast road/track day pads, component life and on track performance markedly improved over competitors pads.

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. True racing only brake calipers generally come with titanium caliper pistons for one reason. Titanium as a material has low thermal conductivity. This means that it is very bad at transferring heat, which is fantastic if you are trying to keep your fluid cool.

The Girodisc solution to help prevent fluid boiling is to use a thin titanium shim placed between the pad back and the pistons, to keep the braking heat from transferring into the pistons and fluid. Here is a comparison of materials and their relative thermal conductivity ratings:

Titanium 6AL-4V 6.7 W/mk
Steel 52 W/mk
Aluminum 130 W/mk

You can see that Titanium will transfer far less heat than steel and especially aluminum. For cars that are going to see hard or multiple track days, these shims are cheap protection from losing the pedal due to boiling at the wrong time and making the day very expensive.

Water jet cut to exact size, no cutting, grinding, or swearing involved.

Price is per axle (four pieces)
