Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

Oil leak from the input rod: During the machining process of the input rod cylinder, a sharp protrusion was produced. This sharp protrusion scratched the packing seal, resulting in an oil leak. Brake pedal kickback: In some cases, the brake pedal may be depressed beyond the operational limit which will create scars on the end of the plunger inside the booster. The scars cause the oil passage to narrow, resulting in unbalanced pressure. The unbalanced pressure causes a kickback sensation to occur. The kickback sensation does not affect the braking function but could lead to the customer contacting the dealer about a possible brake malfunction.
