5. Install and adjust a NEW stop lamp switch. See: Lighting and Horns/Brake Light Switch/Service and Repair/Stop Lamp Switch - Installation.
NOTE: Make sure the output rod (3) of the brake booster is in position and retained by a output rod retaining ring, by looking into the
boosters master cylinder mounting hole. This position will enable the output rod to enter inside of the master cylinder plunger sleeve
during installation. Proper position is obtained when the output rod is centered perpendicular to the master cylinder mounting hole.
NOTE: Prior to installing the master cylinder assembly (1) check that there is a vacuum seal present at the shoulder of the master cylinder
flange and its neck. A square seal must be present to ensure vacuum integrity with the booster.
NOTE: Take precautions to locate the master cylinder plunger over the booster output rod, before installing the master cylinder. If correctly
fitted the master cylinder should slide easily onto the booster output rod before the mounting studs are engaged in the flange holes of
the master cylinder.
6. Gently install the master cylinder (1) on the booster mounting studs and tighten the nuts (2) to 10 Nm (90 in. lbs.).
7. Install the IPM (4) back in place and install the fasteners for the IPM (4).
8. Install the left front wheel well.
9. Install the vacuum hose to the check valve (2).
