Defect
The manufacturing process for the brake master cylinder is improper, causing the rubber cup fitted to the secondary-side piston inside the cylinder to swell on some units. Continued use causes the rubber cup to sustain damage through sliding contact. In the worst case, hydraulic fluid leaks and braking force decreases.
Corrective action
On all vehicles, replace the master cylinder with a non-defective unit.
