Brake System - Bleeding (Natural Gas Model) |
|
|
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.
|
|
Do not reuse the drained fluid. Use only new 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 gets in the
brake fluid.
|
|
|
|
The reservoir connected to the master cylinder must be
at the MAX (upper) level mark at the start of the bleeding
procedure and checked after bleeding each wheel. Add fluid
as required.
|
|
|
|
There are three different methods used for bleeding brake
systems. The method shown here is the preferred manual method
for removing the air from the system. For pressure or vacuum
bleeding, refer to tool manufacturer's instructions included
with the tool.
|
|
|
1.
|
Make sure the brake fluid level in the reservoir tank (A) is
at the MAX (upper) level line (B).
|
|
|

|
2.
|
Start the bleeding at the driver's side of the front brake system.
|
|
NOTE: Bleed the calipers in the sequence shown.
|
|
|
Front

Rear
|
|
3.
|
Attach a length of clear drain tube (A) to the bleed screw (B).
|
|
4.
|
Submerge the other end of the drain tube into a clear plastic
catch bottle of brake fluid (C).
|
|
5.
|
Have an assistant slowly pump the brake pedal several times then
apply steady continuous pressure.
|
|
6.
|
Loosen the bleed screw slowly to bleed the fluid into the plastic
catch bottle. The brake pedal will travel toward the floor as the
fluid is bled from the system.
|
|
7.
|
When the brake pedal reaches the floor, have the assistant hold
the pedal in that position, then tighten the bleed screw. The brake
pedal can now be released.
|
|
8.
|
Check and refill the master cylinder reservoir tank to the MAX
(upper) level line. Be sure to reinstall the master cylinder reservoir
cap.
|
|
9.
|
Repeat steps 5 thru 8 until the brake fluid in the clear drain
tube appears fresh and there are no air bubbles in the fluid.
|
|
10.
|
Repeat this procedure for each brake in the bleeding sequence.
|

|
1.
|
Install the rear wheel.
|
|
NOTE: Before installing the wheel, clean the mating surfaces
between the brake disc or the brake drum and the inside of the wheel.
|
|
|
|
For proper inspection and adjustment of the wheel alignment,
do these checks:
|
|
1.
|
Release the parking brake to avoid an incorrect measurement.
|
|
2.
|
Make sure the suspension is not modified.
|
|
3.
|
Make sure the fuel tank is full, and that the tire repair kit,
the spare tire, the jack, and the tools are in place on the vehicle.
|
|
4.
|
Check the tire size and tire pressure according to tire information.
|
|
|
|
Use commercially available computerized four wheel alignment
equipment to measure wheel alignment (caster, camber, toe, and turning
angle). Follow the equipment manufacturer's instructions.
|
|
1.
|
Check the camber angle.
|
|

| |
Si (Without 18 inch wheel):
|
| |
|

|
| |
|

|
| |
|
Front:
|
-0 ° 18 ’±30 ’
|
| |
|

|
|
(Maximum difference between the front right and
left side: 0 ° 45 ’)
|
|
|
|
|

|
Camber angle:
|
| |
Front:
|
0 ° 20 ’±30 ’
|
| |
Rear:
|
-0 ° 22 ’±45 ’
|
|
(Maximum difference between the front right and
left side: 0 ° 45 ’)
|
|
|
|
|
|
If the measurement is within specification, measure
the toe-in.
|
|
|
|
If the measurement for the front camber is not
within the specification, go to front camber adjustment.
|
|
|
|
If the measurement for the rear camber is not
within the specification, check for bent or damaged
suspension components.
|
|
|
|
| 13. |
Rear Toe - Inspection |
|
|
Use commercially available computerized four wheel alignment
equipment to measure wheel alignment (caster, camber, toe, and turning
angle). Follow the equipment manufacturer's instructions.
|
|
1.
|
Release the parking brake to avoid an incorrect measurement.
|
|
2.
|
Check the toe.
|
|
Rear toe-in: 2+2-1 mm (0.08+0.08-0.04 in)
|
|
|
If adjustment is required, go to the rear toe
adjustment.
|
|
|
|
If no adjustment is required, go to front toe
inspection.
