REMOVING REAR BRAKE DRUM SUB-ASSEMBLY
1. Release the parking brake and remove the rear
If the rear brake drum cannot be removed easily,
do the following:-
2.Remove the hole rubber and insert a screwdriver
through the hole into the backing plate, and hold the
automatic adjust lever away from the adjuster.
3.Using another screwdriver, contract the brake shoe
by turning the adjuster.
4. Take out the brake drum from the flange.
5. remove the shoe hold down spring cup, shoe hold down spring, pin and front side brake shoe.
6. Remove the tension spring. Remove the shoe return spring from the rear brake shoe and remove the parking brake shoe strut set.
7. Remove the shoe holding spring cup, shoe hold spring, pin and rear brake shoe.
8. separate the parking brake cable.
9. Remove the automatic adjust lever tension spring and remove the automatic adjust lever.
10. remove the C-washer and remove the parking brake shoe lever.
NOTE: Do not use any solvent like gasoline to wash the brake parts.
Always wear safety goggles and mask before using compressed air.
Remove the oil or any other coating on the surface's where the brake shoes or pads make contact. This area should be cleaned before installing brake shoes/pads. As for the sand paper for the surface, it is a good idea to lightly sand the contact surface, but just lightly. What is also important is applying anti squeal to the backside (metal side) of the brake pad before installing, and also apply a small bit of grease where the brake shoe hits the backing plate (high spot on the backing plate, there is most likely four raised areas total for each side) on the rear brake assembly....just a small amount will keep the rears from making noise also.
Assuming you have drums in the back,you don't get much in the way of squealing.
I would say the quality of the brake lining is not what you want.
Also you need a clean machined surface on the drums
I would possibly turn the drums, light skim cut,if never done since new
I would use 60 then and 80 grit sand paper on the linings
You need all brakes parts to move correctly,no rust anywhere
and things lubed
Check the parking cables for releasing
If you still have issues,then it is the brake material.
I would only do this work myself
I have never had a brake issues at all, in 47 years
All brake issues are done professionally. Not knocking them,
I just never have issues.
Type of brake shoes there using, the more metallic compound on the shoe will make them Squeal and just takes time for the brake shoes and drums to wear there self to a point where they will not squeal any more. The high Metallic brake shoes will last longer but make more noise, I did a break up grade on my Jimmy with ceramic brake pads and vented rotors. At first before there were broken in, stopping distance was bad and brakes was loud, but now it's like dropping an anchor LOL. Keep me posted and give it a few miles of stop and go traffic.
you mean parking brake cable? loosen parking brake cables put drums on , and adjust shoes till they lightly drag, now apply brakes a few times and check the adjustment again, if all ok, now adjust park brake cables, you want to adjust so park pedal goes 5-8 clicks till the wheels are "locked up" and the wheels spin free with the park brake off
Remove the drum retaining nuts, if equipped, and remove the brake drum.
If the drum will not come off, pry the rubber plug from the backing plate. Insert a narrow rod through the hole in the backing plate and disengage the adjusting lever from the adjusting screw. While holding the adjustment lever away from the screw, back off the adjusting screw with a brake adjusting tool. Be careful not damage the notches in the adjusting screw or the self-adjusting mechanism will not function properly.
Inspect the brake drum for scoring and wear. Replace or machine as necessary. If machining, observe the maximum diameter specification.
If a new drum is being installed, remove the protective coating from the drum using brake cleaner. Sand the drum lightly and wipe with a cloth soaked in denatured alcohol.
Adjust the brake shoes according to the procedure in this Section.
Install the brake drum and the wheel and tire assembly.
I was once told that the squeeling comes form the edges of the brakle pads vibrating when you stop. To fix it, remove the drum and sand off the edges of the brake pad. If you want to get serious, taper the edges of the pads with a grinder. Some Brake pads and shoes come tapered right out of the box. Be conservative only remove a little bit of material.
The squeal is usually the tell tales that make a noise when the front or rear disk pads are worn to where they need replacing. However, with drum brakes, that is an indication of totally worn out shoes, or a broken part. STOP driving the car, go to a mechanic (or friend) and have them checked.
