INFORMATION

BMW brake discs/rotors are stamped with a Minimum Thickness. The stamped minimum thickness is used to determine whether the brake

discs/rotors require replacement during a brake service, such as pad replacement. However, some motor vehicle inspection procedures require the

measurement of brake discs/rotors. An additional minimum thickness specification for the purpose of motor vehicle inspection is provided in the

Technical Data section of the Repair Manual. Examples of the two specifications are described in this bulletin.

The Stamped Minimum Thickness (MIN TH) is utilized as described below:

New brake pads may only be installed if the brake disc thickness is greater than or equal to the minimum brake disc thickness (MIN TH) [not

including M vehicles].

In the case of M vehicles and perforated (cross-drilled) brake discs, new brake pads may only be installed if the brake disc thickness is greater than

the minimum brake disc thickness (MIN TH).

The Minimum Thickness for general inspection (Motor Vehicle Inspection) is defined as follows:

Nominal size thickness minus 2.4 mm (not applicable to perforated brake discs and M vehicles)

M vehicles and perforated (cross-drilled) brake discs: Nominal size thickness minus 1.6 mm

Note:

The nominal size thickness refers to the width of a new rotor.

Always refer to the Repair Manual for model-specific information.

All

INFORMATION

The need to perform a wheel alignment is generally dictated by a component replacement, such as a steering gear, or to address a customer

complaint related to a vehicle's handling characteristics.

Many wheel alignment machines use a multicolored display to indicate alignment measurements, such as camber and toe. Some machines will

display a reading in a red font to indicate that an adjustment is recommended. However, a red display in and of itself does not indicate that the

621

vehicle falls outside of the alignment specifications. Since many of the alignment specifications include a tolerance or variation, always refer to the

alignment specifications in the Repair Manual.

Please note that brand new vehicles and vehicles which have been suspended on a lift may exhibit some deviation from nominal specifications, due

to the fact that the suspension has not fully settled.
