# PARKING BRAKE ADJUSTMENT PROCEDURE REVISION

#### VEHICLES AFFECTED: 1984 Fiero

The parking brake adjustment procedure for the 1984 Fiero found on page 5-13 of the Fiero Service Manual has been revised. The new procedure is as follows:

When the parking brake is in the released position tension measured in the cables at location D is 555N +/- 15N. The method of adjustment is as follows:

#### NOTE: All retainers should be installed before proceeding.

1. Hold the threaded portion of cable A to prevent cable twist during adjustment and tightening.

2. With park brake handle fully released, take up slack in cable E at point D.

3. Apply tension preload to cables by adjusting nut B to provide 555N on cables.

4. Cycle the park brake handle three times, returning cable to the released condition before each apply. After the third apply return cable system to released condition and note that the caliper park brake pull levers are against caliper stop bosses and no cable slack exists at point D. If cable slack is present, readjust cable tension to remove slack without the park brake levers moving off the caliper stops.

#### NOTICE: One tool that is available to measure the cable tension at point D is BT3375K and may be purchased from;
