IBrake Booster Test
Functional Test
1. With the engine stopped, press the brake pedal
several times to deplete the vacuum reservoir, thenpress the pedal hard, and hold itfor 15 seconds. lfthe pedal sinks, either the master cylinder is
bypassing internally, or the brake system (master
cylinder, lines. modulator, or calipers) is leaking.
2. Start the engine with the brake pedal pressed. lf thepedal sinks slightly, the vacuum booster is workingproperly. lf the pedal height does not vary, thebooster or check valve is faulty.
3. With the engine running, press the brake pedal
lightly. lfthe brake pedal sinks more than 1O mm
{3/8 in, ) in 3 minutes, the master cylinder is faulty.A slight change in pedal height when the Ay'C
compressor cycles on and off is normal. (The A,/C
compressor load changes the vacuum available tothe booster.)
Leak Test
1. Press the brake pedal with the engine running, thenstop the engine. lf the pedal height does not vary
while pressed for 30 seconds, the vacuum boosteris OK. lf the pedal rises, the booster is faulty.
2. With the engine stopped, press the brake pedal
several times using normal pressure. When thepedal is first pressed, it should oe row.
On consecutive applications, the pedal height
should gradually rise. lfthe pedal position does notvarv, check the booster check valve.
19-18
3. Disconnect the brake booster vacuum hose (check
valve built-in) (A) at the booster side.
5.
4.Start the engine, and let it idle. There should bevacuum available. lf no vacuum is available, thecheck valve is not working properly. Repiace thebrake booster vacuum hose and check valve, andrelesI.
Reconnect the brake booster vacuum nose.
Start the engine, and then pinch the brake boostervacuum hose between the check valve and thebooster,
Turn the ignition switch OFF, and wait 30 seconds,Press the brake pedal several times using normalpressu re,
When the pedal is first pressed, it should be low.On consecutive applications, the pedal height
should gradually rise.
. lf the pedal position does notvary, replacethe
brake booster.. lf the pedal position varies, replace the brake
booster vacuum hose/check valve assembly.

Conventional Brake Components
Rear Brake Disc Inspection
Runout
1. Raise the rear of the vehicle, and support it with
safety stands in the proper location (see page 1-8).Remove the rear wheels,
2. Remove the brake pads (see page 19-20).
3. Inspect the disc surface for damage and cracks.
Clean the disc thoroughly, and remove all rust,
4. lnstall suita ble f lat washers (A) and wheel nuts, andtighten the nuts to the specified torque to hold thebrake disc securely against the hub.
108 N.m (11.0 kgf.m,80lbf.ft)
Set up the dial gauge against the brake disc as
shown. and measure the runout at 10 mm (0.4 in.)
from the outer edge of the disc.
Brake Disc Runout;
Service Limit: 0.10 mm {0.004 in.)
lf the disc is beyond the service limit, refinish thebrake disc.
Max. Refinish Limit: 9.0 mm (0.35 in.)
NOTE:. lf the brake disc is beyondtheservice limitfor
refinishing, replace it (see page 18-26).. A new disc should be refinished if its runout isgreater than 0.10 mm (0.004 in.).
19-22
Thickness and Parallelism
1. Raise the rear of the vehicle, and support with
safety stands in the proper location (see page l-g).Remove the rear wheels.
2. Remove the brake pads {see page 19 20).
3, Using a micrometer, measure disc thickness ateight points, approximately 45'apart and 10 mm
{0.4 in.) from the outer edge of the disc.
Brake Disc Thickness:
Standard: 9.9-10.1 mm (0.389 0.397 in.l
Max. Retinishing Limit: 9.0 mm (0.35 in.)
Brake Disc Parallelism: 0.016 mm 10.0006 in.)
max.
4.lf the smallest measurement is less than the max.
refinishing limit, replace the brake disc (see page
18-26).
lf the disc is beyond the service limit for parallelism,
refinish the brake disc with an on-car brake lathe.
