  • BRAKES – REDUCED POWER ASSIST DURING OPERATION IN FREEZING AMBIENT TEMPERATURES – LIGHTNING MODELS ONLY
Publication Date: DECEMBER 17, 2001

FORD:
1999-2001 F-150

ISSUE:

Some Lightning model vehicles may exhibit a reduced power assist after the first two or three brake applications during operation in freezing ambient temperatures. This may be caused by current production routing of the brake booster vacuum hose allowing water to collect in the hose which can freeze in cold ambient temperatures.

ACTION:

Verify condition only occurs during freezing ambient temperatures. Replace existing brake booster hose with a new design service part. Refer to the following Service Procedure for details.

SERVICE PROCEDURE

  1. Remove existing brake booster hose and discard.
  2. Install new brake booster hose (1L3Z-9C482-AA). Secure new hose by inserting retainer (included) into the upper hole on the driver’s side of the cowl trim panel (Figure 1).
  3. Road test and verify brake effectiveness.
