is there a picture for drum brakes- how to replace them

Welcome to 10w40.com.

To remove drum brakes:

1. remove the lug nuts and pull the wheel off the hub.
2. Be sure to inspect the rear wheel axle gaskets and wheel seals for leaks.
3. One of the most important safety inspections to be made is that of the brake drum.

* first, visually Inspect The Brake Shoes , as installed on the car. their condition can many times reveal defects in the drums.
* If the linings on one wheel are worn more than the others, it might indicate a rough drum. Uneven wear from side to side on any one set of shoes can be caused by a tapered drum.
* To finish your brake inspection, you'll have to clean the brake parts using the instructions below.
* Clean the backing plates, struts, levers, and other metal parts to be reused using a water-dampened cloth or a water-based solution. Wet cleaning methods must be used to prevent asbestos fibers from becoming airborne.
* Carefully examine the raised shoe pads on the backing plate to make sure they are free from corrosion or other surface defects that might prevent the shoes from sliding freely. Use fine emery cloth to remove surface defects, if necessary. Clean them thoroughly.
* Check to make sure that the backing plates are not cracked or bent. If so, they must be replaced.
* Make sure backing plate bolts and bolted-on anchor pins are torqued to specifications.
* If replacement of the wheel cylinder is necessary, it should be done at this time. To determine Wheel Cylinder condition, carefully inspect the boots. if they are cut, torn, heat-cracked, or show evidence of excessive leakage, the wheel cylinders should be replaced.
* If more than a drop of fluid spills out, leakage is excessive, replacement is necessary.
* Disassemble the adjusting screw assembly and clean the parts in a suitable solvent.
* Make sure the adjusting screw threads into the pivot nut over its complete length without sticking or binding.
* Check that none of the adjusting screw teeth are damaged.
* Lubricate the adjusting screw threads with brake lubricant.
* Examine the shoe anchor, support plate, and small parts for signs of looseness, wear, or damage that could cause faulty shoe alignment.
* Check springs for spread or collapsed coils, twisted or nicked shanks, and severe discoloration.
* Operate star wheel automatic adjusters by prying the shoe lightly away from its anchor or by pulling the cable to make sure the adjuster advances easily, one notch at a time.
* Adjuster cables tend to stretch, and star wheels and pawls become blunted after a long period of use.
* For rear-axle parking brakes, pull on the cable and shoe linkage to make sure no binding condition is present that could cause the shoes to drag when the parking brake is released.
* To complete the drum brake inspection, examine wheel bearings and hub grease seals for signs of damage. Replace if necessary.

TO REPLACE:

* Reassemble the brakes in the reverse order of disassembly .
* Try the fit of the brake drum over the new shoes.
* If not slightly snug, pull it off and turn the star wheel until a slight drag is felt when sliding on the drum.

* A brake preset gauge makes this job easy and final brake adjustment simple.
* Then install the brake drum, wheel bearings, spindle nuts, cotter pins, dust caps, and wheel/tire assemblies, and make the final brake adjustments as specified in individual instructions in the vehicle's service manual.
* Torque the spindle and lug nuts to specifications.

Good luck.
