6.	Rear Suspension All Mounting - Tighten Under Vehicle's Weight

Raise the rear suspension with a floor jack to load the vehicle weight.

Tighten all mounting hardware to the specified torque.

7.	Rear Wheel Speed Sensor, Brake Hose Mounting Bracket, and Brake Line

Install the brake hose mounting bracket (A).

Install the wheel speed sensor (B).

Connect the brake line (C) to the wheel cylinder.

8.	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.

NOTE:

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.

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

x.sm.x1imm

Rear

Attach a length of clear drain tube (A) to the bleed screw (B).

Submerge the other end of the drain tube into a clear plastic catch bottle of brake fluid (C).

Have an assistant slowly pump the brake pedal several times then apply steady continuous pressure.

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.

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.

Check and refill the master cylinder reservoir tank to the MAX (upper) level line. Be sure to reinstall the master cylinder reservoir cap.

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.

9.	Rear Wheel

15mmumum

	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.

10.	Pre-Alignment Checks

For proper inspection and adjustment of the wheel alignment, do these checks:

Release the parking brake to avoid an incorrect measurement.

Make sure the suspension is not modified.

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.

Check the tire size and tire pressure according to tire information.

11.	Camber - 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.

Check the camber angle.

USA and Canada models

Camber angle:
	Except Si:
		Front:	0 ° 00 ’±30 ’
		Rear:	-0 ° 45 ’±45 ’
	Si (Without 18 inch wheel):
		Front:	-0 ° 04 ’±30 ’
		Rear:	-0 ° 52 ’±45 ’
	Si (With 18 inch wheel):
		Front:	-0 ° 18 ’±30 ’
		Rear:	-0 ° 45 ’±45 ’
(Maximum difference between the front right and left side: 0 ° 45 ’)

Mexico models

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.

12.	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.

Release the parking brake to avoid an incorrect measurement.

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.

13.	Test Drive

Test-drive the vehicle.

14.	Rear Stabilizer Link - Tighten

After 5 minutes of driving, torque the self-locking nut again to the specified torque.
