Ferodo Racing Pads

Ferodo brake pads for use in race cars date all the way back to 1926 where they were successfully used in a land speed record run of 169 mph. Today Ferodo racing brake pads are used frequently in the most popular forms of Motorsports both on the track and off the track in cars, karts and motorcycles, with the manufacturing of pads kept in-house to ensure premium quality and consistent braking to provide users with the best possible experience. The DS Range of pads have a coding system which tells the user which compound of pad they are, the part numbers usually begin FCP followed by numbers and then suffix, the range of suffix's consist of the following, a typical pad number would be for example FCP1307H and they would be identified as the DS2500 compound.

  • H = DS2500
  • C = 4003
  • R = DS3000
  • W = DS11.1
  • Z = DSUNO
Ferodo DS2500 are amongst the most popular brake pad for track days and light race use on the front axle, they are also used in pure race vehicles on the rear axle, Average friction coefficient of 0.42 over working temperature range of 20°-500°C. Ferodo 4003 has been developed specifically for lighter race cars such as Formula 3 and Formula Ford / Renault, the compound has very short bed-in times but has excellent bite with low drag the pad has average friction coefficient 0.46 over the working temperature range of 200°-450°C. Ferodo DS3000 is a heavy duty all-round material with short bedding in periods with an average friction coefficient 0.48 over the working temperature range of 200°-650°C used in multiple applications including Group N, Touring Cars, Rally Cars and hill climb. Ferodo DS11.1 Ceramic technology belonging to the chemical family of Siloxane which unlike other compounds these do not decompose at high temperatures and keep on working at the most extreme temperatures encountered in Motorsport braking systems. The pads have an average friction coefficient 0.46 over the working temperature range of 200°-700°C, they are very long life and kind to the discs and can be found on Touring Cars, GT Cars and Single Seat race cars. Ferodo DSUNO is Ferodo's latest in heavy duty race materials for use in Formula, GT and Touring Cars and Rally, this compound has replaced the DS2.11 and has reduced wheel lock when compared to other pads of this friction which is average friction coefficient 0.48 over the working temperature range of 200°-700°C according to Ferodo this is the ultimate feel good pad, which are kind to the brake discs and have a long life.

Brake Fluid

Brake Fluid should be replaced every 2 years and is not mileage dependent, meaning even if you have driven your car for 1 year or more the fluid should still be replaced every 2 years, why? OK, brake fluid is hygroscopic which in laymen terms means it absorbs water from the atmosphere, this absorption deteriorates the fluid by lowering the boiling point of the brake fluid it can also cause an increase in volume within your brake system causing complete brake lockup in rare circumstances. The lower the boiling point of the brake fluid the more likely the chances of vapour lock when this occurs the fluid boils separating the oxygen from the water (just like boiling your kettle) the oxygen now in the brake system greatly reduced the hydraulic efficiency of your brake system, this will be felt as a "Spongy Pedal" feel and you will also notice the brake don't work as well as they should. This is because the pressure in your hydraulic system being applied by your brake master cylinder / brake pedal is being absorbed by the oxygen, the reason being oxygen is compressible and when confined behaves almost spring like where as brake fluid is designed not be compressible. A very easy way to understand this is, if you had a solid steel bar and pushed from one end parallel to the bar the other end would move at exactly the same timing and distance, however if you divided the solid bar and placed small balloons filled with air between each pocket and carried out the same test, the bar at the very front would not move immediately and would not travel the same distance as the rear. The most common type of brake fluid is DOT4 but there is also DOT 3, DOT5 and finally DOT5.1 these fluids are different and its important that you understand why, these can be separated into 2 groups,

  1. Glycol (polyethylene glycol) Based
  2. Silicone (diorgano polysiloxane) Based
Glycol based fluids are the hygroscopic type which means they absorb water as discussed above, where as Silicone based fluids contain at least 70% by weight of a diorgano polysiloxane when replacing DOT 5 fluid extra care should be taken as this fluid does absorb air this is known as hydrophobic the most critical point however is Silicone based fluids and Glycol based fluids should NOT be mixed. Below is the common boiling points for the fluid types.
Type Dry boiling point
DOT 3 205 °C (401 °F) 140 °C (284 °F)
DOT 4 230 °C (446 °F) 155 °C (311 °F)
DOT 5 260 °C (500 °F) 180 °C (356 °F)
DOT 5.1 260 °C (500 °F) 180 °C (356 °F)
Available from our stock are DOT  4 and DOT 5.1, we have standard replacement Mintex DOT 4 available in half litre and 1 litre's and for the DOT 5.1 we have Ferodo racing fluid, which can be used on the road and track.
