Brake Booster Inspection
Functions Tgst
1. With the engine stopped, depress the brake pedal
several times to deplete the vacuum reservoir, then
depress the pedal hard and hold it for 15 seconds. ll
the pedal sinks, either the master cylinder is
bypassing internally; or the brake system (master
cylinder, lines, modulator proportioning valve, orcaliper) are leaking.
Start the engine with the pedal depressed. lf thepedal sinks slightly, the vacuum booster is operat-
ing normally. lf the pedal height does not vary, the
booster or check valve is faulty.
With the engine running, depress the brake pedal
lightly. Apply just enough pressure to hold back
automatic transmission creep, lf the brake pedal
sinks more than 25 mm (1.0 in.) in three minutes,
the master cylinder is faulty. A slight change inpedal height when the A,,/C compressor cycles on
and off is normal. (The A/C compressor load
changes the vacuum available to the booster.)
Leak Test
1. Depress the brake pedal with the engine running,
then stop the engine. lf the pedal height does not
vary while depressed for 30 seconds, the vacuum
booster is OK. lf the pedal rises, the booster is
fau lty.
2. With the engine stopped, depress the brake pedal
several times using normal pressure. When thepedal is first depressed, it should be low. On con-
secutive applications, the pedal height should grad-
ually rise. lf the pedal position does not vary, check
the booster check valve.
Boostor Ch€ck Valve T6st
1. Disconnect the brake booster vacuum hose at the
booster,
Start the engine and let it idle. There should be vac-
uum available. It no vacuum is available. the check
valve is not working properly. Replace the brake
booster vacuum hose and check valve, and retest.

Check the brake disc for damage and cracks.
Make sure that the pad retainers are installed in the
correct positions.

Install the brake pads and pad shims on the caliper
bracket. Install the inner pad with its wear indicator
facing downward.
r When reusing the pads, always reinstall the
brake pads in their original positions to prsvent
