Defect
The hydraulic piston in the brake booster and the retaining spring that secures the pin joining the piston to the push rod are improperly shaped. The spring may dislodge and become trapped between the piston and cylinder, causing the piston to seize in the stroked position and the brake to drag. In the worst case, the overheated brake may catch fire.
Corrective action
On all vehicles, replace the complete brake booster assembly with a corrected part.
