New brake pads must be burnished
before racing or other competitive
driving.
Caution
Performing the brake burnish
procedure on a base brake system
can result in brake damage.
Caution

should be completed before
performing the brake burnish
procedure, otherwise damage may
occur to the powertrain/engine. See

force to increase. This could extend
stopping distance until the brakes
are fully burnished.
When this procedure is performed as
instructed, it will not damage the
brakes. The brake pads will smoke and
produce an odor. The braking force
and pedal travel may increase. After
the procedure, the brake pads may
appear white at the rotor contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor
vehicle operation.
Brake Burnish Procedure (V-Series
and Y4Q only)
1. Apply the brakes 25 times
starting at 100 km/h (60 mph) to
50 km/h (30 mph) while
decelerating at 0.4 g. This is a
medium brake application. Drive
for at least 1 km (0.6 mi)
between applying the brakes.
This first step may be skipped if
there are more than 320 km
(200 mi) on the brake pads.
2. Repeatedly apply the brakes from
100 km/h (60 mph) to 25 km/h
(15 mph) while decelerating at
0.8 g. This is a hard brake
application, without activating
the Antilock Brake System (ABS).
Drive for at least 1 km (0.6 mi)
between stops. Repeat until the
brake pedal travel starts to
increase. Depending on
conditions, this should take no
longer than 25 brake
applications.
3. Cool down: Drive at 100 km/h
(60 mph) for approximately
15 km (10 mi) without using the
brakes.
4. Apply the brakes 25 times from
100 km/h (60 mph) to 50 km/h
(30 mph) while decelerating at
0.4 g. This is a medium brake
application. Drive for at least
1 km (0.6 mi) between
applications.
