2.2.9
Inspect bolts for cracks, thread damage or corrosion, and replace, if
necessary.
2.3 Reassembly
2.3.1
If removed, press anchor bolts (9-100 or 10-100) (see Figure 1) into
brake and install washers (9-30, -30A or 10-30) and nuts
(9-25 or 10-25). Torque nuts to 90 in-lbs.
2.3.2
Install inlet and bleeder fittings.
2.3.3
Lay the cylinder on a firm surface.
2.3.4
For piston installation, lubricate the piston, O-ring, and piston bore
with a small amount of MIL -H-5606 hydraulic fluid. Place piston in
bore and rotate to seat drag ring and insure that piston and seal are
in proper alignment.
2.3.5
Install O-rings into cylinder O-ring grooves.
2.3.6
Insert the pistons until the O-rings (9-55, -55A or 10-55, -55A)
prohibit further insertion. While applying pressure with your thumbs,
rotate the piston in a clockwise direction. After O-ring squeeze is
overcome, the piston will slide freely into the bore. Push piston flush
to cylinder face.
NOTE:
If considerable effort is required, remove piston and inspect bore and
pilot bore area for damage. If the bore is damaged, check the
corresponding area of the piston for damage. Repair, if necessary,
and repeat the above procedure.
2.3.7
Install pressure plate assembly by aligning anc hor bolt holes with
anchor bolts and slide onto cylinder. The pressure plate must float
freely on the anchor bolts.
2.3.8
Install brake assembly to torque plate by aligning anchor bolts with
torque plate holes and sliding brake assembly onto torque plate (it
must slide freely).
2.3.9
Install washers, cylinder tie-bolts, and insulator shim. Install back
plate assemblies between brake disc and wheel flange, and align with
tie-bolts. Torque bolts to 85-90 in-lbs.
2.3.10 Reconnect hydraulic lines and bleed system. Check pedal for proper
feel and travel.
