3. Apply vacuum slowly and continuouslv whilewatching the gauge. The vacuum should stabilizemomentarily at 0.7 - 2.0 kpa (5 - 1S mmHg, 0.2 _ 0.6in.Hg).
lf the vacuum stabilizes (valve opens) below0.7 kPa (5 mmHg,0.2 in,Hg) or above 2.0 kpa(15 mmHg, 0.6 in.Hg), install a new valve and retest.

Inspection and Replacement
1.
Nsvgr u9e an air hose or dry brush to clean brake
assemblies.
Use an OSHA approved vacuum cleaner to avoid
broathing brake dust.
Loosen the front wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the front wheels.
Remove the caliper bolt, and pivot the caliper up
out of the way. Check the hoses and pin boots for
damage and deterioration.

4. Using vernier calipers, measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thickness:
Standard: 10.5 - 11.5 mm {0.,11 - 0.45 in)
Servics Limit: 1.6 mm (0.06 in)
lf the brake pad thickness is less than the service
limit. replace the front pads and shims together as a
set.
Clean the caliper thoroughly; remove any rust, and
check for grooves and cracks.
Check the brake disc for damage and cracks.
Install the pad retainers.

Disassembly/Reassembly
. Never use an air hose or dry brush to clean brake assemblies.
. Use an OSHA approved vacuum cleaner to avoid breathing brake dust.
. Contaminated brake discs or pads reduce stopping ability.
. When reusing the pads, always reinstallthe brake pads in their original positions to prevent loss ol braking efficiency.
CAUTION:
. Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid does contact the paint, wash it off imme-
diatelY with water.
NOTEI
. To prevent spills, cover the hose joints with rags or shop towels.
. Clean all pans in brake fluid and air dry; blow out all passages with compressed air.
. Before reassembling, check that all parts are free of dust and other foreign particles.
. Replace parts with new ones whenever specified to do so.
. Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
. Do not reuse the drained fluid.
. Always use Genuine Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and decrease the
life of the system.
. Coat the piston, piston seal, and caliper bore with clean brake fluid.
. ReDlace all rubber oarts with new ones whenever disassembled.
. After installing the front brake caliper do the following.- Check for leaks at hose and line joints and connections, and retighten if necessary.- Check the brake hoses for interference and twistinq.
