DIAGNOSIS
BRAKE SYSTEM TESTING
Brakes should be tested on a dry, clean, reasonably smooth and level roadway. A true test of brake performance cannot be made if the roadway is wet, greasy, or covered with loose dirt whereby all tires do not grip the road equally. Testing will also be adversely affected if the roadway is crowned so as to throw the weight so roughly that the wheels tend to bounce. Test the brakes at different vehicle speeds with both light and heavy pedal pressure; however, avoid locking the brakes and sliding the tires. Locked brakes and sliding tires do not indicate brake efficiency since heavily braked, but turning, wheels will stop the vehicle in less distance than locked brakes. More tire­to­road friction is present with a heavily­braked, turning tire than with a sliding tire. Because of the high deceleration capability, a firmer pedal may be felt at higher deceleration levels. There are three major external conditions that affect brake performance: S Tires having unequal contact and grip of the road will cause unequal braking. Tires must be equally inflated, and the tread pattern of the right and the left tires must be approximately equal. Unequal loading of the vehicle can affect the brake performance since the most heavily loaded wheels require more braking power, and thus more braking effort, than the others. Misalignment of the wheels, particularly conditions of excessive camber and caster, will cause the brakes to pull to one side.

S

Check for a binding pedal linkage and for an incorrect pushrod length. If both of these parts are in satisfactory condition, disassemble the master cylinder and check for an elongated or swollen primary cylinder or piston seals. If swollen seals are found, substandard or contaminated brake fluid should be suspected. If contaminated brake fluid is found, all the components should be disassembled and cleaned, and all the rubber components should be replaced. All of the pipes must also be flushed.

Improper brake fluid, or mineral oil or water in the fluid, may cause the brake fluid to boil or cause deterioration of the rubber components. If the primary piston cups in the master cylinder are swollen, then the rubber parts have deteriorated. This deterioration may also be evidenced by swollen wheel cylinder piston seals on the drum brake wheels. If deterioration of rubber is evident, disassemble all the hydraulic parts and wash the parts with alcohol. Dry these parts with compressed air before reassembly to keep alcohol out of the system. Replace all the rubber parts in the system, including the hoses. Also, when working on the brake mechanisms, check for fluid on the linings. If excessive fluid is found, replace the linings. If the master cylinder piston seals are in satisfactory condition, check for leaks or excessive heat conditions. If these conditions are not found, drain the fluid, flush the master cylinder with brake fluid, refill the master cylinder, and bleed the system. Refer to "Manual Bleeding the Brakes" or"Pressure Bleeding the Brakes" in this section.

S

BRAKE HOSE INSPECTION
The hydraulic brake hoses should be inspected at least twice a year. The brake hose assembly should be checked for road hazard damage, cracks, chafing of the outer cover, and for leaks or blisters. Inspect the hoses for proper routing and mounting. A brake hose that rubs on a suspension component will wear and eventually fail. A light and a mirror may be needed for an adequate inspection. If any of the above conditions are observed on the brake hose, adjust or replace the hose as necessary.

S

To check for brake fluid leaks, hold constant foot pressure on the pedal with the engine running at idle and the shift lever in NEUTRAL. If the pedal gradually falls away with the constant pressure, the hydraulic system may be leaking. Perform a visual check to confirm any suspected leaks. Check the master cylinder fluid level. While a slight drop in the reservoir level results from normal lining wear, an abnormally low level indicates a leak in the system. The hydraulic system may be leaking either internally or externally. Refer to the procedure below to check the master cylinder. Also, the system may appear to pass this test while still having a slight leak. If the fluid level is normal, check the vacuum booster pushrod length. If an incorrect pushrod length is found, adjust or replace the rod. Check the master cylinder using the following procedure: S Check for a cracked master cylinder casting or brake fluid leaking around the master cylinder. Leaks are indicated only if there is at least one drop of fluid. A damp condition is not abnormal.

WARNING LAMP OPERATION
This brake system uses a BRAKE warning lamp located in the instrument panel cluster. When the ignition switch is in the START position, the BRAKE warning lamp should glow and go OFF when the ignition switch returns to the RUN position. The following conditions will activate the BRAKE lamp: S Parking brake applied. The light should be ON whenever the parking brake is applied and the ignition switch is ON. Low fluid level. A low fluid level in the master cylinder will turn the BRAKE lamp ON. EBD system is disabled. The light should be ON when the EBD system is malfunctioning.

9. Test Description The number(s) below refer to step(s) on the diagnostic table. 1. When the ignition is turned ON, the brake warning lamp should initially illuminate and then dim for ABS equipped vehicles. This is done as a bulb check. On vehicles that are not equipped with ABS, the brake warning lamp should only illuminate when either the brake fluid reservoir is low or the parking brake is applied. The brake fluid level switch is a normally open switch. If the brake warning lamp is off after disconnecting the switch, the brake fluid level switch is stuck closed. 12.

19.

24. 30. 32.

7.

If the brake warning lamp is still on after disconnecting the parking brake switch, there is a short to ground in the wire to the parking brake switch. If the other checks have been properly performed and the brake warning lamp is off after disconnecting the electronic brake control module (EBCM) J1 connector, the EBCM is faulty. If the brake warning lamp does not operate while performing any of the functions, the fault should be in the ignition feed to the circuit. This step determines if the problem is in the ignition feed to the circuit or in the instrument cluster. The brake warning lamp should illuminate when jumpering the parking brake connector to ground. If the brake warning lamp is on after jumpering the brake fluid level switch terminals, the switch is faulty.

6. Slowly push and hold the brake pedal one time.

7. 8.

9.

Loosen the front brake line at the master cylinder to purge air from the cylinder. Tighten the brake line (as in step 5), and then release the brake pedal slowly. Wait 15 seconds before proceeding to the next step. Repeat the sequence, including the 15­second wait, until all the air is removed from the master cylinder bore.

Notice : Care must be taken to prevent brake fluid from contacting any painted surface to prevent damage to the paint finish. 10. After all the air has been removed at the forward connection(s), bleed the master cylinder at the rear (cowl) connection(s) in the same manner as with the front connections.

Important : For vehicles equipped with a non­antilock braking system, the bleeding sequence is as follows: right rear, left rear, left front and right front. For ABS vehicles, refer to Section 4F, Antilock Brake System for the correct sequence and bleeding procedure. 11. Attach a transparent tube over the valve. Allow the tube to hang submerged in brake fluid in a transparent container.

12. Slowly push and hold the brake pedal one time. 13. Remove the bleeder valve dust cover and loosen the bleeder screw to purge the air from the cylinder. 14. Tighten the bleeder screw.

Tighten
Tighten the bleeder screw to 8 NSm (71 lb­in). 15. Slowly release the brake pedal. Wait 15 seconds before proceeding with the next step. Important : Rapid pumping of the brake pedal pushes the master cylinder secondary piston down the bore in a manner that makes it difficult to bleed the system. 16. Repeat the sequence, including the 15­second wait, until all the air is removed. It may be necessary to repeat the sequence 10 or more times to remove all the air. 17. Locate the front bleeder caps. 18. Proceed to bleed the front brakes following the appropriate sequence, beginning with step 12. 19. Check the brake pedal for sponginess. Repeat the entire bleeding procedure to correct this condition. 20. Replace the bleeder valve dust cover.

PRESSURE BLEEDING THE BRAKES
Notice : Pressure bleeding equipment must be of the diaphragm type. It must have a rubber diaphragm between the air supply and the brake fluid to prevent air, moisture, oil, and other contaminants from entering the hydraulic system. Contamination could lead to deterioration of the braking components and loss of braking action. 1. Disconnect the master cylinder electrical connector. 2. Remove the master cylinder reservoir cap.

3. 4.

5. 6. 7.

Connect the bleeder with the adapter to the master cylinder reservoir. For vehicles with the antilock braking system (ABS), locate and remove the hydraulic modulator bleeder valves. Refer to Section 4F, Antilock Brake System. Charge the bleeder ball to 140 to 172 kPa (20 to 25 psi). Connect the line to the adapter. Open the line valve. Raise and suitably support the vehicle.
