Bedding-In of New/Replacement Brake Pads
To ensure that brake pads and discs are correctly 'bedded-in' on new cars,
the factory road test the car and perform the following brake bedding-in
procedure:
1. Three light brake applications from 80-50 kph (50-30 mph) using normal
acceleration to 80 kph.
2. Three medium applications from 110-65 kph (70-40) mph using normal
acceleration up to 110 kph.
3. Two hard applications from high speed to 50 kph (30 mph), again using
normal acceleration.
4. Drive a further 8 km (5 miles) with minimal brake use.
5. Stop and allow the brakes to cool.
6. Drive a further 8 km (5 miles) back to the workshop with normal brake
use.
Aston Martin dealers are required to perform this routine each time brake
pads / discs are replaced.
Aston Martin require owners to perform this routine if pads or discs are
replaced by a non-franchised workshop who will not know of the correct
bedding in procedure.
Failure to bed-in the brake pads / discs will result in reduced brake
performance and possible brake judder or squeal.
