SOURCE: the brake light on the

There is a level switch in the master cylinder if the fluid level is low it will turn on the light and If you pressure or vacuum bleed the brakes you will center the proporting valve switch that warns of low brake pressure in either Front or rear.
Vacuum bleeding I have found to work the best.
Make sure the Park brake lever is all the way released. If you find this informationn helpful please leave me a favorable rating and by all means contact me if I can be of any further help.

SOURCE: how to remove the rear drum off a GMC W4500

This is a full floating axle. The drum and the hub come off together. The axle must be pulled by removing the bolts or nuts on the hub center.Then the large nuts behind it must be removed. Now the hub and drum assembly can be removed. If you've already done that and the drum still won't come off back off the brake adjuster as far as possible. A ridge of rust sometimes forms inside the lip of the drum that will keep it from sliding off until the shoes are backed off. Very worn shoes can also literally wear grooves into the drum and make it impossible to remove until the adjusters are backed all the way off. If everything is rusted solid and you can't get anything to move check with the owner and, if it's O.K. with him, take the sawsall or the torch and cut the lower part of the backing plate out of your way. Then cut the adjuster in half. Now the drum will come off.

1999 Ford E350 van problem: brake pedal is soft; have replaced master cylinder, rear wheel cylinders, rear brake shoes and drums, front calipers, rotors and discs; have bled master cylinder before...


Good question, on the antilock system is a bleader too and bleade it the same way you bleade the caliper. After all is done adjust the rear brakes, they should have a drag to them.

How to remove brake rotors on a 1996 ford explorer


How to replace the rear brake pads on a 1995 through 2001 Ford Explorer The system utilizes a drum-in-hat type rear brake rotor. The integral drum allows the use of a drum-and-shoe type parking brake system. All other components are similar to their front disc brake components Remove the two bolts on either side of the brake hose with the rubber boots. Do not remove the four bolts where the axle ties in. The two bolts to be removed require a 10mm socket/wrench. Loosen the pads from the caliper Rotor Removal In order to take the rotors off (replace with new or have them machined), it is best to loosen the emergency brake shoes. To do this, behind the rotors, in the back there is a rubber plug, remove that and you can use a screw driver to engage the teeth of the adjusting screw, turn it clockwise to loosen, usually 10-20 teeth. Usually this means turn it downward. After this, it may still be difficult to get the rotors off without tapping them. Use a rubber mallet and hit them from behind. Before really whacking the rotor, make sure you have loosened the adjusting screw enough. It may take heavy swings of the rubber hammer to do this. It will eventually break loose. Parking Brake You might want to check the parking brake while you are here. To remove:
  • Remove the rear disc brake rotor.
  • Remove the outboard return spring.
  • Remove the adjusting screw spring.
  • Remove the rear brake shoe hold-down spring and pin.
  • Remove the brake shoe adjusting screw and nut.
  • Remove the front brake shoe hold-down spring and pin.
  • Remove both parking brake shoes and the inboard return spring.
  • Check the parking brake lever for excessive wear and replace as necessary.
To install:
  • Position the front parking brake shoe to the backing plate and install the hold-down pin and spring.
  • Install the rear parking brake shoe with the inboard return spring.
  • Position the brake shoe adjuster screw and nut on the shoes and install the rear shoe hold-down pin and spring.
  • Install the brake shoe adjuster spring.
  • Install the outboard return spring.
  • Adjust the parking brake shoes and install the rotor, caliper and wheel.
  • Lower the vehicle and tighten the wheel lug nuts to 100 ft. lbs. (135 Nm).
ADJUSTMENT
  • Measure the inside of the drum portion of the rear brake rotor
  • Remove the rear disc brake rotor.
  • Using Brake Adjustment Gauge D81L-1103-A or equivalent, measure the inside diameter of the drum portion of the rear disc brake rotor.
  • Subtract 0.020 in. (0.508mm) from the first measurement, adjust the brake shoes to that size
  • Adjust the parking brake adjuster screw until the outside diameter of the parking brake shoes measures 0.020 in. (0.508mm) less than the drum measurement.
  • Install the rear disc brake rotor.
Reassembly Reassembly is easy. Put new or machined rotors back on by sliding them over the lugs (they should slide on easily.) Loosen bleeder valve (having a catch bottle handy is good). Push calipers in slowly (using a c-clamp or large channel lock pliers), close bleeder valve. Put on pads. Lubricate metal clips with small amount of anti-seize. Re-adjust the emergency brake by turning the opposite direction from loosening. Refill the brake master cylinder

Spongy brake pedal even after ABS bleed and base brake bleed.


Did you adjust the rear shoes out? If the rear drum brakes are out of adjustment they will give you a lot of pedal travel. If the pads are worn have no fear of that U-CLIP brake spring, just change one shoe at a time. Take the spring off one side, change the shoe, put the spring back on the post and do the same to the other shoe, no problem.
