Brake Bleeding
Brake Bleeding Information
WARNING!
When bleeding the brake system, wear safety glasses. A clear bleed tube must be attached to the bleeder
screws and submerged in a clear container filled partially with clean brake fluid. Direct the flow of brake fluid
away from yourself and the painted surfaces of the vehicle. Brake fluid at high pressure may come out of the
bleeder screws when opened.
CAUTION:
Before removing the master cylinder cap, wipe it clean to prevent dirt and other foreign matter
from dropping into the master cylinder reservoir. Use brake fluid or an equivalent from a fresh,
tightly sealed container. Brake fluid must conform to DOT 4 specifications.
NOTE :
During the brake bleeding procedure, be sure the brake fluid level remains close to theMAXlevel in the master
cylinder fluid reservoir. Check the fluid level periodically during the bleeding procedure and add brake fluid as
required.
NOTE :
Do not pump the brake pedal at any time while having a bleeder screw open during the bleeding process. This will
only increase the amount of air in the system and make additional bleeding necessary. Do not allow the master
cylinder reservoir to run out of brake fluid while bleeding the system. An empty reservoir will allow additional air into
the brake system. Check the fluid level frequently and add fluid as needed. The following wheel circuit sequence for
bleeding the brake hydraulic system should be used to ensure adequate removal of all trapped air from the hydraulic
system.
Brake Bleeding Procedure
The following wheel circuit sequence for bleeding the brake hydraulic system should be used to ensure adequate
removal of all trapped air from the hydraulic system:
• Left rear wheel
• Right front wheel
• Right rear wheel
• Left front wheel
Manual Brake Bleeding
NOTE :
To bleed the brakes manually, the aid of a helper will be required.
Fill the brake master cylinder reservoir to the proper level with brake fluid.

Downloaded from www.Manualslib.com manuals search engine NOTE :
Never allow the brake master cylinder to empty of brake fluid while bleeding the brake system.
Attach a clear plastic hose to the bleeder screw and
feed the hose into a clear jar containing enough fresh
brake fluid to submerge the end of the hose.
1. Turn the ignition switch off.
2. Have a helper pump the brake pedal three or four times and hold it in the down position.
3. With the pedal in the down position, open the bleeder screw at least one full turn.
4. Once the brake pedal has dropped, close the bleeder screw. After the bleeder screw is closed, release thebrake pedal.
5. Repeat the above steps until all trapped air is removed from that wheel circuit (usually four or five times).
6. Bleed the remaining wheel circuits in the same manner until all air is removed from the brake system. Monitor the fluid level in the master cylinder reservoir to make sure it does not go dry.
7. Check and adjust brake fluid level to the MAXmark.
8. Check the brake pedal travel. If pedal travel is excessive or has not been improved, some air may still be trapped in the system. Re-bleed the brakes as necessary.
9. Test drive the vehicle to verify the brakes are operating properly and pedal feel is correct.
Pressure Brake Bleeding
NOTE :
Follow pressure bleeder manufacturer’s instructions for use of pressure bleeding equipment.
Fill the brake master cylinder reservoir to the proper level with brake fluid.
Attach the pressure bleeding equipment to the master cylinder.
NOTE :
Never allow the brake master cylinder to empty of brake fluid while bleeding the brake system.
Attach a clear plastic hose to the bleeder screw and
feed the hose into a clear jar containing enough fresh
brake fluid to submerge the end of the hose.
1. Turn the ignition switch off.
2. Open the bleeder screw at least one full turn or more to obtain a steady stream of brake fluid.
3. After approximately 120-240 ml of fluid has been bled through the brake circuit and an air-free flow is main- tained in the clear plastic hose and jar, close the bleeder screw.
4. Repeat this procedure at all the remaining bleeder screws.
5. Check and adjust brake fluid level to the MAXmark on the reservoir.

Description
The calipers are a single piston type. The calipers are free to slide laterally on the anchor, this allows continuous
compensation for lining wear. The calipers are directly bolted to the wheel hub with mounting bolts. The brake rotor
dust shield is mounted to the hub.
Operation
When the brakes are applied, fluid pressure is exerted against the caliper piston. The fluid pressure is exerted
equally and in all directions. This means pressure exerted against the caliper piston and within the caliper bores will
be equal. Fluid pressure applied to the pistons is transmitted directly to the inboard brake pad. This forces the pad

the caliper to slide inward on the slide pins. This action brings the outboard brake pad lining into contact with the
outer surface of the disc brake rotor.
Removal & Installation
1. Using a brake pedal holding tool, depress the brake pedal past its first 25 mm of travel and hold it in this posi-tion. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid to
drain out of the master cylinder reservoir when the lines are opened.
2. Raise and support the vehicle.
3. Remove the wheel mounting nuts and the tire and wheel assembly. (Tighten: Wheel mounting nuts to 110 N·m)
4. Using a large C-clamp (2), push the caliper piston to an adequate depth to remove the brake caliper
(1) from the brake disc.
5. Remove the front brake hose from the front brake caliper. (Tighten: Front caliper brake hose to 19 N·m)
6. Remove the front caliper guide pin bolts (1). (Tighten: Front caliper guide pin bolts to 23 N·m)
7. Slide the front brake caliper from the disc brake adapter bracket and remove.
8. Installation is in the reverse order of removal.
Installation Notes:
• Completely retract the caliper piston back into the bore of the caliper.
• After installation, bleed the caliper as necessary.
Rear Brake Caliper
Description
The rear disc brakes consist of fixed single piston style calipers and solid rotors. The rear caliper is mounted to the
rear wheel hub. The calipers are directly bolted to the wheel hub with mounting bolts. The disc brake rotor dust shield
is mounted to the hub. The brake rotor has a built in drum used for the parking brakes. The parking brake shoes are
mounted to the wheel hub.

Inspection
Excessive runout or wobble in a rotor can increase pedal travel due to piston knock-back. This increases guide pin
sleeve wear due to the tendency of the caliper to follow the rotor wobble.
Braking Surface Inspection
Light braking surface scoring and wear is acceptable. If heavy scoring or warping is evident, the rotor must be resur-
faced or replaced. Excessive wear and scoring of the rotor can cause improper lining contact on the rotor’s braking
surface. If the ridges on the rotor are not removed before new brake pads are installed, improper wear of the shoes
will result. Some discoloration or wear of the rotor surface is normal and does not require resurfacing when linings
are replaced. If cracks or burned spots are evident, the rotor must be replaced.
Rotor Minimum Thickness
Measure the rotor thickness (1) at the center of the
brake pad contact surface. Replace the rotor (2) if it is
worn below minimum thickness or if machining the rotor
will cause its thickness to fall below specifications.
CAUTION:
Do not machine the rotor if it will cause the rotor to fall below minimum thickness.

brake rotor.
• Check and adjust the brake fluid level in the reservoir as necessary.
• Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the
brake pads.
• After installation and before moving the vehicle, pump the brake pedal several times to set the pads to the
brake rotor.
Inspection
Visually inspect brake pads for uneven lining wear. Also inspect for excessive lining deterioration. Check the clear-
ance between the tips of the wear indicators (if equipped) on the pads and the brake rotors. If a visual inspection
does not adequately determine the condition of the lining, a physical check will be necessary. To check the amount
of lining wear, remove the disc brake pads from the vehicle. Measure the brake pad minimum thickness. Brake pads
must be replaced when usable material on a brake pad lining measured at its thinnest point measures one millimeter
or less. Replace both disc brake pads (inboard and outboard) at each caliper. It is also necessary to replace the pads
on the opposite side of the vehicle as well as the pads failing inspection to maintain proper braking characteristics.
If the brake pad assemblies do not require replacement, be sure to reinstall the brake pads in the original position
from which they were removed.
