Tech Tip: Mini Cooper Rear Brake Calipers Sticking

The rear brake calipers on any Cooper or Cooper S produced up to August 2004 may stick and cause the wheel to slightly drag when turning. This can be seen when the vehicle is suspended on a lift and is more likely to occur on the right side than on the left side.

The rear brake calipers on any Cooper or Cooper S produced up to August 2004 may stick and cause the wheel to slightly drag when turning. This can be seen when the vehicle is suspended on a lift and is more likely to occur on the right side than on the left side. The cause is residual handbrake braking torque from unfavorable routing of the handbrake cable. If this condition is noted, modify the curvature of the handbrake cable elbow.

Service Procedure:
1. Do not replace the handbrake cable or brake caliper.
2. Lift up the vehicle.
3. Slightly bend the handbrake cable elbow down to widen the angle (See arrow, Fig. 1).
4. Check to ensure free movement of the wheel (no binding or dragging when turning).
5. Repeat the bending of the elbow as necessary.

Note: Do not bend the handbrake cable elbow with excessive force.

This high-voltage system was a solution for the power required for loads such as electric power steering. It got as far as an SAE standard so OEMs and suppliers could implement these systems. What happened? The simple answer is that engineers improved how 12-volt power was managed in the vehicle.
