Brake Disc Bedding
NOTE: Ideally new brake discs should only be bedded in with used bedded pads
Brake discs must be bedded in to allow heat stabilisation and improve resistance to cracking. Cracks
and disc failure can occur during the first few heavy stops if bedding in is not carried out therefore
McLaren Customer Racing recommends the following procedure for disc bedding:
1.
For a minimum of 15 km, use brakes gently at first from initially low speeds, progressively raising
speed to normal racing speed but still using gentle brake application
2.
For the final 2 or 3 applications, the brakes can be used fairly heavily
3.
Thermal paint is recommended to monitor brake temperature. If AP Racing thermal paints are
used, then the following is optimal:
a.
Green paint (430 °C) should have turned fully white
b.
Orange paint (560 °C) should have partially turned white on the edges of the discs
c.
Red paint (610 °C) should not have turned white
4.
Allow brakes to cool
Brake Pad Bedding
NOTE: Ideally new brake pads should only be bedded in with used bedded discs
The following procedure has been formulated to allow the best possible bedding of friction material
to disc, and also to thermally condition the iron rotor. This should leave the brake system in a suitable
position to begin track running. The procedure will take approximately 30 minutes. At no point should
ABS be used when bedding. Brakes should be below 40°C when starting this procedure.
1.
6 x 160kph to 60kph with 40% braking effort
2.
3km of cooling
3.
6 x 160kph to 60kph with 80% braking effort
4.
3km of cooling
5.
2 -3 full ABS braking events to confirm the pads are fully bedded and that the steering is straight
under braking.
