Ferodo DS 2500 brake pads for Alfa 33 (907).
DS 2500 pads are among the best high performance track day pads in the business.
They are also suitable for some light duty front and many rear pure race applications.
The DS 2500 pads offer excellent refinement for such a high performance pad. The main characteristics are:
- track day and light race use for all vehicle types
- road style refinement but with race material ability to withstand heat with respect to life and friction coefficient
- average friction coefficient of 0.42 over a working temperature range of 20°-500°C
DS 2500 pads are not recommended for street use and may only be used in combination with high-carbon sports brake discs.No homologation, not street legal.
The price is for the complete axle (4 pads).Variant 1:
for Alfa 33 from 1990 on with Bendix / Lucas-Girling-calliperVariant 2:
for Alfa 33 from 1990 on with ATE-calliperImportant information: bedding of race pads
The aim is to bring the pads to full race temperatures, but slowly (too quick bedding results in glazing). This is done by a series of laps where full speeds may be attained but lighter braking pressures are used (i.e. the driver applies the brakes earlier). It is important that the pads are allowed to cool after the bedding process before racing. Ideally the pads will arrive at temperatures in excess of 500°C during the bedding. Smoking pads during the cool-down are not a cause for concern.
Perform at least 15 trial brake applications, initially with reduced pressures (50% of the normal that might be used for that same brake application were it to occur under race conditions) building up to full decelerations after the 15 applications. To shorten the procedure applications can be made along the straights as well as at corners.
On completion of the trial applications, return to the pit lane. Inspect the surface of the brake pads from the two wheels that have been working the hardest. There should be evidence of contact over the full pad area, but without glazing. The pads are now ready to race. Whilst it is recommended that pads are inspected after bedding, if time does not allow this and paragraph 1 has been carried out appropriately, so long as a short period of time has elapsed to allow the brake system to cool (ideally to below 100°C – this might take in excess of five minutes), the pads will be ready to race.
