I need replacement bands for shoes that are frayed

Remove rear wheels and the brake rotors. parking/Emegency brake shoes are inside these rotors. Check shoes if worn, replace them Your Emergency brake is self adjustable.

OPERATION
A hand operated lever in the passenger compartment is the main application device. The front cable is connected between the hand lever and the rear cables with an equalizer.

The rear cables are connected to the actuating lever on each primary brake shoe. The levers are attached to the brake shoes by a pin either pressed into, or welded to the lever. A clip is used to secure the pin in the brake shoe. The pin allows each lever to pivot independently of the brake shoe.

To apply the parking brakes, the hand lever is pulled upward. This pulls the rear brake shoe actuating levers forward, by means tensioner and cables. As the actuating lever is pulled forward, the parking brake strut (which is connected to both shoes), exerts a linear force against the secondary brake shoe. This action presses the secondary shoe into contact with the drum. Once the secondary shoe contacts the drum, force is exerted through the strut. This force is transferred through the strut to the primary brake shoe causing it to pivot into the drum as well.

A gear type ratcheting mechanism is used to hold the lever in an applied position. Parking brake release is accomplished by the hand lever release button.

A parking brake switch is mounted on the parking brake lever and is actuated by movement of the lever. The switch, which is in circuit with the red warning light in the dash, will illuminate the warning light whenever the parking brakes are applied.

Parking brake is self-adjusting when the lever is pulled. The cable tensioner, once adjusted at the factory, should not need further adjustment under normal circumstances.
REMOVAL

1. Raise and support the vehicle.
2. Remove the tire and wheel assembly.

1. Remove the disc brake caliper.
2. Remove the disc brake rotor.

Brake Shoe

1. Disassemble the rear park brake shoes.

CLEANING - REAR DRUM IN HAT BRAKE
Clean the individual brake components, including the support plate exterior, with a water dampened cloth or with brake cleaner. Do not use any other cleaning agents. Remove light rust and scale from the brake shoe contact pads on the support plate with fine sandpaper.

INSPECTION - REAR DRUM IN HAT BRAKE
As a general rule, riveted brake shoes should be replaced when worn to within 0.78 mm (1/32 inch) of the rivet heads. Bonded lining should be replaced when worn to a thickness of 1.6 mm (1/16 inch) .
Brake Shoe

Examine the lining contact pattern to determine if the shoes are bent or the drum is tapered. The lining should exhibit contact across its entire width. Shoes exhibiting contact only on one side should be replaced and the drum checked for runout or taper.

Inspect the adjuster screw assembly. Replace the assembly if the star wheel or threads are damaged, or the components are severely rusted or corroded.

Discard the brake springs and retainer components if worn, distorted or collapsed. Also replace the springs if a brake drag condition had occurred. Overheating will distort and weaken the springs.

Inspect the brake shoe contact pads on the support plate, replace the support plate if any of the pads are worn or rusted through. Also replace the plate if it is bent or distorted.

INSTALLATION

NOTE: On a new vehicle or after parking brake lining replacement, it is recommended that the parking brake system be conditioned prior to use. This is done by making one stop, from 25 mph on dry pavement or concrete using light to moderate force on the parking brake lever.

1. Reassemble the rear park brake shoes.

a worn clutch shoe or brake band is the most common cause, remove the side cover and actuate the brake, if you can wiggle the shoe or turn it at all then its for sure the shoe or band

could be several problems, The blade could be worn, tires worn, axles loose and the front pulley support could be bent. I would try and watch to see what wheel it starts coming off of and then concentrate on that to find the problem. Let me know if you need more assistance.

Remove valve body and clean

Could be several things: The calipers (for disc pads) or wheel cylinders (for shoes) are worn and dirty and are sticking. These would need to be rebuilt or replaced. You could check it by jacking up the car, applying the brakes then see if the wheels move freely after letting off the brake. Could also be warped rotors (if pads). Or, I had a car that brakes locked up and I realized that the new shoes I had put on had gotten oil on them somehow. I put a 2nd new set on and fixed the problem.

Yes you can get a replacement watch band here:
www.casiowatchesusa.com -

If you need to screw the band adjustment in that far chances are that there is no friction material left on the band. If you keep driving like that the band will begin to eat into the drum and shed fine metal (like what happens to worn brake shoes when they eat up the drum) which can and will contaminate the remainder of the internal hydraulics and do even more damage. Nothing worthwhile you can do to fix the problem short of replacing it with a scrapyard unit (including converter) or having yours rebuilt.

Check and see if one of the guides is out of alignment or if the blade is worn. Either one can cause the problem since you already checked the tension and guides. If the guides are worn they won't hold the blade true.

Sounds like your brake pads/shoes need replaced. When the brake linings wear out, you have metal to metal when you step on your brake pedal. You may have to replace rotors/drums due to severe scarring.
