We talked about it, but here is GM's guide to proper vehicle brake-in.
Starting and Operating
New Vehicle Break-In
Follow these recommended guidelines during the first 2 414 km (1,500 mi) of driving this vehicle. Parts have a break-in period and performance will be
better in the long run.
For the first 2,414 km (1,500 mi):
- Avoid full throttle starts and abrupt stops.
- Do not exceed 4,000 engine rpm.
- Avoid driving at any one constant speed, fast or slow.
- Do not drive above 129 km/h (80 mph).
- Do not tow a trailer.
- Avoid downshifting to brake or slow the vehicle when the engine speed will exceed 4,000 rpm.
- Do not let the engine labor. Never lug the engine in high gear at low speeds. With a manual transmission, shift to the next lower gear. This
rule applies at all times, not just during the break-in period.
- Do not participate in racing events, sport driving schools, or similar activities during this break-in period.
- Check engine oil with every refueling and add if necessary. Oil and fuel
consumption may be higher than normal during the first 2,414 km (1,500 mi).
- To break in new tires, drive at moderate speeds and avoid hard cornering for the first 322 km (200 mi). New tires do not have maximum traction and may tend to slip.
- New brake linings also need a break-in period. Avoid making hard stops during the first 322 km (200 mi). This is recommended every time brake linings are replaced.
- Should the vehicle be used for racing or competitive driving (after break-in), the rear axle lubricant must be replaced before hand.
My thoughts on break-in for all aspects of the car:
