Always use a ball joint remover to disconnect a ball
joint. Do not strike the housing or any other part of
the ball joint connection to disconnect it.
1. Install a hex nut (A) or the ball joint thread protector onto the threads of the ball joint (B).
NOTE: Using a hex nut, make sure the nut is flush
with the ball joint pin end to prevent damage to the
threaded end of the ball joint pin.
2. Apply grease to the ball joint remover on the areas shown (A). This will ease the installation of the tool,
and prevent damage to the pressure bolt (B)
threads. 3. Loosen the pressure bolt (A), and install the ball
joint remover as shown. Insert the jaws carefully,
making sure not to damage the ball joint boot.
Adjust the jaw spacing by turning the adjusting bolt
(B).
NOTE: Fasten the safety chain (C) securely to a
suspension arm or the subframe (D). Do not fasten
it to a brake line or wire harness.
4. After adjusting the adjusting bolt, make sure the head of the adjusting bolt is in the position shown
to allow the jaw (E) to pivot.
5. With a wrench, tighten the pressure bolt until the ball joint pin pops loose from the ball joint
connecting hole. If necessary, apply penetrating
type lubricant to loosen the ball joint pin.
NOTE: Do not use pneumatic or electric tools on
the pressure bolt.
6. Remove the ball joint remover, then remove the nut from the end of the ball joint pin, and pull the
ball joint out of the ball joint connecting hole.
Inspect the ball joint boot, and replace it if
damaged.

System Communication
18-60TPMS
System Description (cont’d)
Control Unit
(With Radio Frequecy Antenna)
Tire Pressure Sensor
(Sensor-transmitter with acceleration sensor)
 When the vehicle is traveling more than 45 km/h (28 mph), an RF (radio frequency) band wave signal is transmitted
from each tire pressure sensor to the control unit.
 When the wheels rotate, and the tire pressure sensors momentum is detected, switching them from sleep mode to normal function (awake) mode. After the vehicle is stationary for 5 minutes, the sensors switch from normal
function mode back to sleep mode to extend their battery life.
 Each tire pressure sensor has its own ID to prevent jamming by similar systems on other vehicles. After memorizing all the sensor IDs, the control unit recognizes only those specific signals.
 An ID cannot be memorized automatically. The control unit knows which ID belongs to each tire pressure sensor. This recurring ID confirmation prevents any confusion in the system as a result of normal tire rotation.
NOTE: Be careful not to bend the brackets on the TPMS control unit: Misalignment of the control unit could interfere
with sending and receiving signals.

NOTE: Make sure the TPMS control unit mounting
bracket is not bent or twisted as this may affect its
communication with the tire pressure sensors.
1. Turn the ignition switch to LOCK (0).
2. Remove the driver’s dashboard undercover (see page 20-103).
3. Disconnect the TPMS control unit connector (A).
4. Remove the TPMS control unit (B) from the bracket (C).
NOTE: To disconnect the TPMS control unit from its
bracket, insert a small flat-tipped screwdriver
between the TPMS control unit and the bracket
shown in (D) to release the hook, then slide out the
TPMS unit.
5. Replace the bracket if necessary. 6. Install the new TPMS control unit in the reverse
order of removal.
NOTE: Make sure the TPMS control unit is properly
installed. You will hear a click when the TPMS
control unit is securely mounted on the bracket.
7. Connect the HDS, and memorize the tire pressure sensor IDs using the TPMS sensor initializer tool
(see page 18-52).

NOTE:
 Do not reuse the drained fluid. Use only clean Honda DOT 3 Brake Fluid from an unopened container.
Using a non-Honda brake fluid can cause corrosion
and shorten the life of the system.
 Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
 Do not spill brake fluid on the vehicle, it may damage the paint; if brake fluid does contact the paint, wash it
off immediately with water.
 The reservoir connected the master cylinder must be at the MAX (upper) l evel mark at the start of the
bleeding procedure, and checked after bleeding each
wheel location. Add fluid as required.
1. Make sure the brake fluid level in the reservoir (A) is at the MAX (upper) l evel line (B).
2. Have someone slowly pump the brake pedal several times, then apply steady pressure.
3. Start the bleeding at the driver’s side of the front brake system.
NOTE: Bleed the calipers in the sequence shown. 4. Attach a length of clear drain tube (A) to the bleed
screw (B), then loosen the bleed screw to allow air
to escape from the system. Then tighten the bleed
screw securely.
5. Refill the master cylinder reservoir to the MAX (upper) l evel line.
6. Repeat the procedure for each brake circuit until there are no air bubbles in the fluid.

to hold the brake disc securely against the hub.
6. Set up the dial gauge against the brake disc as shown, and measure the runout at 10 mm (0.39 in.)
from the outer edge of the brake disc. 7. If the brake disc is beyond the service limit, refinish
the brake disc with a Honda-approved
commercially available on-car brake lathe.
NOTE: If the brake disc is beyond the service limit for refinishing, replace it (see page 19-21).
 If the brake disc is replaced with a new one, check the new disc for runout. If the new disc is
out of specification, refinish the disc.

Functional Test
Leak Test
19-26 Conventional Brake Components
Brake Booster Test
A
1. With the ignition switch in LOCK (0), press the
brake pedal several times to deplete the vacuum
reservoir, then press the brake pedal hard, and hold
it for 15 seconds. If the brake pedal sinks, either the
master cylinder is bypassing internally, or the
brake system is leaking. Inspect the brake hoses
and lines (see page 19-37).
2. Start the engine with the brake pedal pressed. If the brake pedal sinks slightly, the vacuum booster is
operating normally. If the brake pedal height does
not vary, do the brake system test (see page 19-4).
1. Press the brake pedal with the engine running, then stop the engine. The brake pedal height should not
vary while pressed for 30 seconds.
 If the pedal height rises, go to step 6.
 If it does not rise, go to step 2.
2. Start the engine and let it idle for 30 seconds. Turn the ignition switch to LOCK (0), and wait
30 seconds. Press the brake pedal s everal times
using normal pressure. When the pedal is first
pressed, it should be low. On consecutive
applications, the pedal height should gradually rise.
Does the pedal rise on each consecutive
application?
 If it rises the booster is OK.
 If it does not rise, go to step 3. 3. Disconnect the brake booster vacuum hose (A) at
the booster. The check valve is built into the hose.
NOTE: If the check valve is faulty, replace the brake
booster vacuum hose/check valve as an assembly.
4. Start the engine, and let it idle. There should be vacuum available.
 If no vacuum is available, the check valve is not working properly. Replace the brake booster
vacuum hose and check valve, and retest.
 Ifthereisvacuum,gotostep5.
5. With the ignition switch in LOCK (0), reconnect the vacuum hose to the brake booster.
6. Start the engine, and then pinch the brake booster vacuum hose between the check valve and the
booster.
7. Turn the ignition switch to LOCK (0), and wait 30 seconds. Press the brake pedal several times
using normal pressure. When the pedal is first
pressed, it should be low. On consecutive
applications, the pedal height should gradually rise.
 If the pedal position does not vary inspect the seal between the master cylinder and booster. If
the seal is OK, replace the brake booster.
 If the pedal position varies, replace the brake booster vacuum hose/check valve as an
assembly.
