Master Cylinder/Brake Booster
Pushrod Glearance Adjustment
NOTEr
. The master cylinder pushrod-to-piston clearancemust be checked and adjustments made, if neces_sary, before installing the master cylinder.. ABS type is shown, conventional brake type is similar.
1. Set the special tool on the master cylinde. body; push
in the center shaft until the top of it contacts the endofthe secondary piston by turning the adjusting nut.
Without disturbing the center shaft's Dosition, installthe specialtool upside down on the booster.Install the master cylinder nuts, and tighten to thespecified torque.
Connect the booster in-line with a vacuum gauge O _
101 kPa (0 - 760 mmHg, 30 in.Hg) to the booster,sengine vacuum supply, and maintain an enginespeed that will deliver 66 kpa (500 mmHg, 20 in.Hg)vacuum.
With a feeler gauge. measure the clearance Detweenthe gauge body and the adjusting nut as shown.

NOTE: lf the clearance between the gauge bodyand adjusting nut is 0.4 mm (0.02 in), the pushrod-to-piston clearance is 0 mm. However, if the clear_ance between the gauge body and adjusting nut is0 mm, the pushrod-to-piston clearance is 0.4 mm(0.02 in) or more. Therefore, it must be adjusted andrechecked.
6. lf clearance is incorrect, loosen the star locknut, andturn the adjuster in or out to adjust.
NOTE;
. Adjust the clearance while the specified vacuumis applied to the booster.. Hold the clevis while adjusting.

Disc Runout Inspection
1.Loosen the front wheel nuts slightly, then raise thevehicle, and suppon it on safety stands. Removethe front wheels.
Remove the brake pads (see page 19-24).
Inspect the disc surface for damage and cracks.Clean the disc thoaoughly, and remove a

rust.
Use wheel nuts and suitable plain washers to holdthe disc securely against the hub. then mount a dialindicator as shown. and measure the runout at10 mm (0.4 in) from the outer edge of the disc.
Brake Disc Runout:
Service Limit:0.10 mm {0.00,t in)
5. lf the disc is beyond the service limit, refinish thebrake disc,

Inspection
1. Loosen the front wheel nuts slightly, then raise thevehicle, and support it on safety stands. Removethe front wh6els.
2. Remove the brake pads (see page j9-24).
3. Using a micrometer. measure disc thickness aterght points, approximately 45" apart and 1o mm{0.4 in) in from the outer edge of the disc. Replacethe brake disc if the smallest measurement is lessthan the max. refinishing limit.
Brake Disc Thickness:
Standard: 8.9 - 9.1 mm (0.350 - 0.358 in)Max. Rsfinishing Limit: 8.0 mm {0.31 in}

NOTE; This is the maximum allowable differencebetween the thickness measurements.
4. lf the disc is beyond the service limit for Darallelism.refinish the brake disc.
NOTE; See section 18 for brake disc replacement.
