Brake Burnishing
The brakes should be properly burnished
prior to heavy track use. Excessive brake
noise may occur after the track burnish or
track use. Perform this procedure in a safe
manner on dry pavement, and in
compliance with all local and state
ordinances and laws regarding motor
vehicle operation.
How to Burnish the Brakes
Initial low temperature bedding:
• If your brakes already have 200 mi
(322 km) or more of city driving, skip
this step and go directly to the high
temperature bedding cycle procedure.
Otherwise, perform at least 30 stops
from 50 mph (80 km/h) at 1/3 g
deceleration with 1 mi (1.2 km) spacing
between stops. A deceleration gauge
can be accessed through the
TrackApps menu in your information
display.
High temperature bedding cycle:
• Beginning with cool brakes, perform 15
consecutive stops back to back,
accelerating at 3/4 throttle to 80 mph
(128 km/h) and braking to 20 mph
(32 km/h) at 1.0 g deceleration. The
brakes may omit an odor or smoke
during this part of the procedure.
Cool down:
• Cool the brakes down by driving one or
two laps, 5 mi (8 km), at 60 mph
(96 km/h) with minimal to no brake
usage.
Recovery low temperature bedding:
• Perform at least 30 stops from 50 mph
(80 km/h) at 1/3 g deceleration with
0.7 mi (1.2 km) spacing between stops.
A deceleration gauge can be accessed
through the TrackApps menu in your
information display.
