SOURCE: front wheel bearing replacement on 2003 Pontiac Montana

Sometimes you will need special removal tools, depending on the vehicle. I'd suggest only having a mechanic replace them for you.
If you want to check what side is bad, just jack up one front wheel
at a time and grab the wheel with 2 hands and wiggle it up and down
and right to left , to see how much play is there. You will be able to
tell which side is worse, by how much more play one side has over the
other, if just one side is bad.Good luck.

I have an 01 GMC Jimmy 4.3L 4WD & we are trying to bleed the brakes but the scanner says my vehicle is going 3MPH so we manually bleed the brakes but the pedals still easily is pushed to the floor.


Bad master cylinder . What are you using a scan tool for ? No need Unless your Installing a new Electro-Hydraulic Control Unit (EHCU) or new Brake Pressure Modulator Valve (BPMV).
Hydraulic Brake System Bleeding (Manual)
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.
Place a clean shop cloth beneath the brake master cylinder to prevent brake fluid spills.
With the ignition OFF and the brakes cool, apply the brakes 3-5 times, or until the brake pedal effort increases significantly, in order to deplete the brake booster power reserve.
If you have performed a brake master cylinder bench bleeding on this vehicle, or if you disconnected the brake pipes from the master cylinder, you must perform the following steps:
3.1. Ensure that the brake master cylinder reservoir is full to the maximum-fill level. If necessary add GM approved brake fluid from a clean, sealed brake fluid container. Refer to Fluid and Lubricant Recommendations.
If removal of the reservoir cap and diaphragm is necessary, clean the outside of the reservoir on and around the cap prior to removal.
3.2. With the rear brake pipe installed securely to the master cylinder, loosen and separate the front brake pipe from the front port of the brake master cylinder.
3.3. Allow a small amount of brake fluid to gravity bleed from the open port of the master cylinder.
3.4. Reconnect the brake pipe to the master cylinder port and tighten securely.
3.5. Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.
3.6. Loosen the same brake pipe to purge air from the open port of the master cylinder.
3.7. Tighten the brake pipe, then have the assistant slowly release the brake pedal.
3.8. Wait 15 seconds, then repeat steps 3.3-3.7 until all air is purged from the same port of the master cylinder.
3.9. With the front brake pipe installed securely to the master cylinder, after all air has been purged from the front port of the master cylinder, loosen and separate the rear brake pipe from the master cylinder, then repeat steps 3.3-3.8.
3.10. After completing the final master cylinder port bleeding procedure, ensure that both of the brake pipe-to-master cylinder fittings are properly tightened.
Fill the brake master cylinder reservoir with GM approved brake fluid from a clean, sealed brake fluid container. Ensure that the brake master cylinder reservoir remains at least half-full during this bleeding procedure. Add fluid as needed to maintain the proper level.
Clean the outside of the reservoir on and around the reservoir cap prior to removing the cap and diaphragm.
Install a proper box-end wrench onto the RIGHT REAR wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve.
Submerge the open end of the transparent hose into a transparent container partially filled with GM approved brake fluid from a clean, sealed brake fluid container.
Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.
Loosen the bleeder valve to purge air from the wheel hydraulic circuit.
Tighten the bleeder valve, then have the assistant slowly release the brake pedal.
Wait 15 seconds, then repeat steps 8-10 until all air is purged from the same wheel hydraulic circuit.
With the right rear wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right rear hydraulic circuit install a proper box-end wrench onto the LEFT REAR wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
With the left rear wheel hydraulic circuit bleeder valve tightened securely, after all air purged from the left rear hydraulic circuit, install a proper box-end wrench onto the RIGHT FRONT wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
With the right front wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right front hydraulic circuit, install a proper box-end wrench onto the LEFT FRONT wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
After completing the final wheel hydraulic circuit bleeding procedure, ensure that each of the 4 wheel hydraulic circuit bleeder valves are properly tightened.
Fill the brake master cylinder reservoir to the maximum-fill level with GM approved brake fluid from a clean, sealed brake fluid container.
Slowly depress and release the brake pedal. Observe the feel of the brake pedal.
If the brake pedal feels spongy, repeat the bleeding procedure again. If the brake pedal still feels spongy after repeating the bleeding procedure, perform the following steps:
21.1. Inspect the brake system for external leaks. Refer to Brake System External Leak Inspection.
21.2. Pressure bleed the hydraulic brake system in order to purge any air that may still be trapped in the system.
Turn the ignition key ON, with the engine OFF. Check to see if the brake system warning lamp remains illuminated.
Important: If the brake system warning lamp remains illuminated, DO NOT allow the vehicle to be driven until it is diagnosed and repaired.
If the brake system warning lamp remains illuminated, refer to Symptoms - Hydraulic Brakes

1996 camery station wagon , 4 wheel disc brakes. need to replace brake lines in the rear. what is the name of the junction block , with the actuator in the rear? All 4 rear lines go to and leave this...


Hello, first you Toyota has dual braking system. It goes like this: Left front brake with right rear brake, the right front brake with left rear brake. This a braking safety system that has been incorporated in auto/trucks for a few years now. If brake line is broken. loose wheel caliper, blow caliper piston, any thing that happens to the brake system. You will still have two wheels that have their hydraulic system. Also, the emergency brake will a manual system for the rear wheels.


Why do you need to change your auto brake lines? That valve you are talking about is a load stabilizer valve. It used to limit the amount of hydraulic fluid as more load is place in the rear of your Toyota. Example. by press on the brake pedal, it activates hydraulic pressure to the four wheel disk braking system. The braking system needs to stabilize the hydraulic pressure to the wheel to keep the vehicle moving in a forward motions. Now, by loading the rear of the vehicle this transfer the load disposition of the vehicle by making it heaver in the rear. Therefore, the load compensator valve limit the amount of hydraulic pressure to the rear brakes.



Another thing to remember about this rear load valve, they will get plugged. and the vehicle will not have enough braking pressure for the rear wheels. I hope I answer you question about this load portion valve in the rear of Toyota. GB...stewbison

The Auto 4 wheel drive is controled by an electronic silinoid. If the silinoid is going bad it will cause it to shift in and out of 4 wheel drive. I hope this helps you out, and if you have any more questions please feel free to ask.

try checking your silinoid. Some of these newer vehicles have an electronic silinoid that is responsible for engaging your transfer case into four wheel drive. Also if you have push button or shift on the fly four wheel drive your switch may have gone bad. I hope this helps you.

Brake light stays on in dash 96 ford thunderbird


Hi, there are 3 things that can cause the light to stay on.
One is the parking brake switch, which may have shorted internally or to chassis ground. The switch is above the parking brake pedal. If the connector is still on the switch remove it. If the light goes out, replace the switch.

The second is the fluid level in the master cylinder reservoir. Check fluid level. If good, check the sensor by taking the cable off. If that puts the light out, replace the sensor.

The third is the pressure differential warning switch. The switch turns on when there is a brake failure. You would probably know if this happened. If not, check all wheels for brake fluid leaks. If you have a leak and need help with repair procedures, please get back to me. If you have completed repairs, please read the procedures below from autozone.com to reset the warning switch.

Please let me know if you have any questions and thanks for using FixYa.


From autozone.com:
A pressure differential warning valve is incorporated in the hydraulic system. The signal from this valve consists of a warning light on the dashboard activated by a differential pressure switch located below the master cylinder. The signal indicates a hydraulic pressure differential between the front and rear brakes of 80-150 psi, and should warn the driver that a hydraulic failure has occurred.
After repairing and bleeding any part of the hydraulic system the warning light may remain on due to the pressure differential valve remaining in the off-center position. To centralize the valve a pressure difference must be created in the opposite branch of the hydraulic system that was repaired or bled last.
Front wheel balancing of cars equipped with disc brakes may also cause a pressure differential in the front branch of the system.


VALVE CENTERING PROCEDURE

  1. Turn the ignition to either the ACC or ON position.
  2. Check the fluid level in the master cylinder reservoirs. Fill to within 1 / 4 in. (6mm) of the top if necessary.
  3. Depress the brake pedal firmly. The valve will centralize itself causing the brake warning light to go out.
  4. Turn the ignition off.
  5. Prior to driving the vehicle, check the operation of the brakes and obtain a firm pedal.

this problem is only caused by one thing on this late model car, that is a leaking hydraulic control valve in the ABS unit, this allows brake pressure to be applied to the caliper pistons without any input from the driver.

Recently service 4 wheel drive lamp came on. And brake slide when


Check the electro-hydraulic control unit mounted on the left side frame underneath the cab. Its made up of the brake pressure modulator valve (bpmv) and the electronic brake control module (ebcm). This controls hydraulic pressure to the brake calipers to prevent wheel lock up. Also check the abs sensor mounted on the transfer case.

ABS brake module sounds like a motor running and won't stop unless battery is disconnected. what is fix?


I would pull the fuse for the ABS hydraulic pump and then put it back in and see what happens. Don't ever recall a pump running. Dealer may need to hook up scan tool for diagnostic fault codes, DTCs.



Principles of Operation
The ABS control module receives wheel speed readings from both front wheel speed sensors and the rear differential speed sensor, and processes this information to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth of the ABS sensor indicators as it passes through the wheel speed sensor's magnetic field.
The ABS control module continuously monitors and compares the rotational speed of each wheel speed sensor indicator and, when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper(s). This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS control module returns the solenoid valves to their normal position, and normal (base) braking resumes.
The ABS control module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS control module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the pump motor is turned on for approximately one-half second. Any malfunction of the ABS system will cause the ABS to shut off; normal power assisted braking, however, remains.
Inspection and Verification — Scan Tool Communications Check
  1. Verify the customer concern by carrying out the Drive Cycle Test.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

Brake line diagram


Brake Lines and Hoses
Double-walled steel line is used in the hydraulic lines between the brake master cylinder and the front tube connector, and between the brake master cylinder and the flexible brake hose at the rear wheels.
Double-flared brake lines provide good leak-proof connections.
When replacing hydraulic brake lines, hoses, or connectors, tighten all connections securely. After replacement, bleed the brake system; refer to Section 206-00 .
The wet appearance of the outer cover of the rubber brake hose is referred to as "sweating." This is a normal condition for neoprene rayon braid hose and is not a sign of leakage or cause for replacement of the hose.
