Booster Operation InspectionS7RS0B4106016
There are two ways to perform this inspection, with and
without a tester. Ordinarily, it is possible to roughly
determine its condition without using a tester.
NOTE
For this check, make su re that no air is in
hydraulic line.

Check Air Tightness
1) Start engine.
2) Stop engine after running for 1 to 2 minutes.
3) Depress brake pedal several times with the same load as in ordinary braking and observe pedal travel.
If pedal goes down deep the first time but its travel
decreases as it is depressed the second and more
times, air tightness is obtained.
4) If pedal travel doesn’t change, air tightness isn’t obtained.
NOTE
If defective, inspect vacuum lines and sealing
parts, and replace any faulty part. When this
has been done, repeat the entire test.

Check Operation
1) With engine stopped, depress brake pedal several times with the same load and make sure that pedal
travel doesn’t change.
2) Start engine while depressing brake pedal. If pedal travel increases a little, operation is satisfactory. But
no change in pedal travel indicates malfunction.
Check Air Tightness Under Load 1) With engine running, depress brake pedal. Then stop engine while holding brake pedal depressed.

2) Hold brake pedal depressed for 30 seconds. If pedal height does not change, condition is good. But it isn’t
if pedal rises.

CAUTION!
• Clean around caliper with brake fluid before disassembly.
• Be careful not to damage inside (bore side) of cylinder.

1) Remove piston with air blown into flexible hose bolt installation hole.
WARNING!
Do not apply too highly compressed air
which will cause piston to jump out of
cylinder. Place a cloth (1) to prevent piston
from damage. It should be taken out
gradually with moderately compressed air.
Do not place your fingers in front of piston
when using compressed air.

2) Remove cylinder boot.
3) Remove piston seal using a thin blade like a thickness gauge, etc.
4) Remove bleeder plug and cap from caliper.

Assembly
Assemble parts in reverse order of disassembly,
observing the following instructions.
CAUTION!
• Wash each part cleanly before installation in the same fluid as the one used in master
cylinder reservoir.
• Never use other fluid or thinner.
• Before installing piston seal or cylinder boot to cylinder, apply brake fluid to them.
• Install a new piston seal into groove in cylinder securely making sure that it is not
twisted.
• Before installing caliper to carrier, check for slid pin smooth movement in thrust
direction.
• After reassembling brake lines, bleed air from them.

• Install piston seal, boot and piston to caliper referring to the following instructions.
1) Replace with a new piston seal (1) at every overhaul. After applying rubber grease (included in repair kit)
or brake fluid, fit piston seal (1) into groove in
cylinder taking care not to twist it. 2) Before inserting piston (1) into cylinder, apply rubber
grease (included in repair kit) or brake fluid to new
boot “a” and install it onto piston as shown.
3) Fit boot as it is in figure into boot groove in cylinder with fingers.
4) Insert piston into cylinder by hand and fit boot in boot groove in piston.
