INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

Check the inner wall of cylinder for corrosion, wear, and damage. If a malfunction is detected, replace cyl-
inder body.

Minor flaws caused by corrosion or a foreign material can be removed by polishing a surface of the inner
wall with a fine sandpaper. Replace cylinder body, if a malfunction is detected.
To r q u e M e m b e r
Check for wear, cracks, and damage. If a malfunction is detected, replace applicable part.
Piston
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.
Check piston surface for corrosion, wear, and damage. If a malfunction is detected, replace applicable part.
Sliding Pin, Sliding Pin Bolt, and Sliding Pin Boot
Check sliding pins and sliding pin boots for wear, damage, and cracks. If a malfunction is detected, replace
applicable part.
ASSEMBLY
1. Apply polyglycol ether based lubricant to the piston seal, and
install them to the cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply rubber grease to piston boots. Cover the piston end with
piston boot, and install cylinder-side lip on piston boot properly
into groove on cylinder body.
CAUTION:
Do not reuse piston boot.
3. Apply brake fluid to piston, and press piston into cylinder body
by hand to assemble piston-side lip on piston boot properly into
a groove on piston.
CAUTION:
Press piston evenly and change pressing point to prevent
inner wall of cylinder from being rubbed.

DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cracks, and serious damage. If a malfunction is detected,
replace applicable part.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
NOTE:
Make sure that wheel bearing axial end play is with in the speci-
fication before measuring runout. Refer to FA X - 4 , "
On-Vehicle
Inspection" .
3. If runout is outside limit, find the minimum runout point by shift-
ing the mounting positions of disc rotor and wheel hub by one hole.
4. If runout is still outside the limit after performing the above operation, replace or lathe the disc rotor.
[When lathing, use the Pro–Cut PFM On–Car Brake Lathe (Tool No. 38–PFM90.5) or equivalent.]
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side standard, replace disc rotor.

DISASSEMBLY
1. Insert a piece of wood as shown in the figure, blow air in through
the flare nut mounting hole, and remove the piston and piston
boot. If the four pistons do not all come out at the same time,
press the piston(s) that have come out a ways into the cylinder
body and blow air in again.

CAUTION:

Be careful not to damage cylinder inner wall.

Never remove the four bolts from the inner and outer
sides of the caliper. Do not tighten them further, either.
CALIPER INSPECTION
Caliper
CAUTION:

Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

Check for corrosion, wear, or damage to the cylinder inner wall, and replace the caliper if there are
any non-standard conditions.
Piston
CAUTION:

Since the piston surface is plated, do not repair using sandpaper.

Check piston surface for corrosion, wear, and damage. If any non-standard condition is detected,
replace applicable part.

Thickness Inspection
Using a micrometer, check thickness of the disc rotor. If thickness is
outside the standard, replace disc rotor.
Brake Burnishing ProcedureNFS000AX
Burnish the brake pad and disc rotor mutually contacting surfaces of disc rotor according to following proce-
dure after refinishing or replacing disc rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:

Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.

Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.Standard

WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne
particles or other materials.
CAUTION:

While removing cylinder body, never depress the brake pedal because the piston will pop out.

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of the caliper assembly. In this case, hang cylinder body with a wire so as not to
stretch brake hose.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shims and shim covers as a set when replacing brake pads.

Keep disc rotor clean of brake fluid.
