Bedding in Ferodo DS2500 pads?

Recommended Posts

I fitted a set of Ferodo DS2500 pads to my car at the weekend, haven't driven the car yet, but what bedding-in process have people used.

 

I have tried 'searching' but there's lot's of threads about DS2500/DS3000 pads and haven't seen anything specific about bedding-in.

 

I got both front and rears from Tim Philips at Circuit Supplies in Leighton Buzzard, turned out we went to the same school, so did his wife who works there as well, so got a bit of extra discount.

He was very knowledgeable about different pads and compounds, He actually supplies Tuthils with the Ferodo's and has just shipped a big quantity to them for their Kenya Safari cars that are competing next month.

 

 

As I was picking them up I paid £108.26 in total.

 

Part No.'s for peoples reference were:-

 

Fronts - FCP11H

Rears - FCP2H

 

These are to fit standard 3.2 Carrera calipers.

Hi Steve,

 

I had this info stashed on my PC:

 

1) Perform 25 to 30 trial brake applications, each of approximately 4 seconds, using around 50% of normal race pedal pressure. To shorten the procedure applications can be made along the straights as well as through bends.

 

2) On completion of trial applications return to the pit lane. Inspect the surface of the brake pads from the two wheels which 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.

I got this from somewhere on the Internet ages ago - not sure if it's relevant to what you want but may be worth a read (or two).

 

BRAKE PAD BEDDING IN PROCEDURE

 

To ensure maximum performance and customer satisfaction, new brake pads must be bedded in upon installation. Correct bedding guarantees that new brake pads and new rotors work flawlessly together. In order to function optimally, organic brake pads must develop friction coal on its surface. This friction coal develops at a temperature of approximately 280°C (537°F). It is very important that this temperature is reached continuously and slowly. This gradual process generates temperatures that not only penetrate the surface of the brake discs and pads, but also distribute evenly through the whole disc and pad material. This is essential when using new brake discs, since the disc often shows signs of stress (due to the casting process and fast cooling) in the materials. A steady and careful warming and cooling process guarantees a good release of both materials.

 

The bedding in/break in procedure should be done as follows:

 

Drive at approx. 35 mph (60 kmh) for about 500 yards (solid front discs) to 800 yards (vented front discs) while slightly dragging the brakes (i.e. light brake pedal pressure). This process allows the brake temperature to slowly and evenly build up to 300°C (572°F).

Now, if possible, drive about 2200 yards maintaining the same speed without braking. This will allow the pads and discs to cool down evenly. After this cool-down, perform a normal brake application from 35 mph to 0. No panic stops!

Now, the friction surface has evenly developed friction coal, the pads have bonded with the disc surface, and tensions in the disc materials will have disappeared.

Only trained master mechanics should perform this procedure before delivering the vehicle to its owner. Do not expect your customer to properly finish your brake job!

This bedding process is only suitable for the front axle - not the rear. This is due to the brake force distribution of front and rear axles. In order to reach 300°C (527°F) on the rear pads you would have to drive several miles with dragging brakes. However, in that time the front brakes will be glowing red, overheating and thus destroying the front brakes.

Final note – don’t forget to clean hubs and check the wheel bearings. Also, the brake fluid should be replaced at least every 2 years.

Cheers Chaps,

 

Tim at Circuit Supplies did tell me how to bed them in but I could'nt remember what he said, (it's an age thing)

Fitted them Friday afternoon but haven't had time to drive it yet.

There is paperwork in the box so I'll check that as well.
