Purpose of deglazing the brake drum - 2002 Pontiac Sunfire

Remove brake pads..front. Deglaze discs and pads and use created on the back of the pads.
Discs must be grease free.
When installed and sensor fitted, ensure sliders are free before pumping brake pedal a few times.
Road test and remember to bedcin brakes again for 500 miles

The linkage could need to be adjusted. Or the brake shoes inside the rear drums are worn out and need to be replaced. If you accidentally drive the brake on. It doesn't take long to wear those brake shoes out. You can normally smell them when that happens. On today's vehicles they are actually designed with 3 different brake systems. Front brake disc and rotors, rear disc and rotors, and inside the rear brake rotor their is a small brake drum where the emergency brake shoes are located. The only purpose for the shoes and drums is emergency brake only (normally). Hope this helps.

Lisle tool 50600 Back Single Spring Brake Tool is made just for this purpose. Makes it a piece of cake. Nightmare to do without it.

Yes this may sounds like the brakes have glazed over. This best way to fix this is to replace the pads and get the drum skimmed. At a local dealer, they will put the drum on a special lathe, and take a very small cut from the inside diameter of the drum. They will also measure the drum first, to see how viable it is to skim or wether full replacement is your best and cheapest option. After skimming it will have the finish comparable to a brand new drum. Also check the operation of the slave cylinder (what operates the pads) to be sure that is working correctly. Goodluck! Let me know how you got on.

Welcome to FIxYa.com

Due to the regulation on asbestos, brake pads and shoes no longer have that chemical in them. The best thing to do is shamfer the ends of the pads. Too, deglaze the pad by sanding it as well.

You may need a brake pad replacement. Have the brake system checked by a professional.

CAUTION
Brake shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid. NOTE: A brake spring removal tool and a brake adjusting gauge are required for this procedure.

1. Raise and support the vehicle safely with jackstands.
2. If the brakes have never been serviced before, the drums will be held on the wheel studs with spring nuts. Remove the spring nuts and discard.
3. Turn the adjustment starwheel so that the brake shoes are retracted from the brake drum and remove the brake drum.
4. Install wheel cylinder clamps to retain the wheel cylinder pistons in place and prevent leakage of brake fluid while replacing the shoes.
5. Remove the U-clip and washer securing the adjuster cable to the parking brake lever.
6. Remove the adjuster cable, cable guide, adjuster lever and adjuster springs. Remove the return springs with a brake spring remover tool.
7. Remove the hold-down retainers and springs, then remove the brake shoes. To install:
   
8. Clean the backing plate with a brush or cloth. Place a dab of Lubriplate® on each spot where the brake shoes rub on the backing plate. NOTE: Always replace brake linings in axle sets. Never replace linings on one side or just on one wheel.
   
9. Thoroughly clean and lubricate the adjuster cable guides, adjuster screw and pivot, parking brake lever and lever pivot pin with multi-purpose grease.
10. Apply a thin coat of multi-purpose chassis lube to the mounting pads on the backing plate.
11. Transfer the parking brake actuating lever to the new secondary shoe.
12. Position the brake shoes on the backing plate, then install the hold-down springs and retainers. Don't forget to engage the parking brake lever with the cable.
13. Install the parking brake actuating bar and spring between the parking brake lever and primary shoe.
14. Install the self-adjusting cable, cable guide and upper return springs.
15. Thoroughly clean the starwheel and lightly lubricate the threads with lithium based grease.
16. Install the starwheel.
17. Install the self-adjusting cam and lower spring. A big pair of locking pliers is good for this job.
18. Check the surface of the brake shoes for any grease that may have gotten on them. If dirty, lightly clean with a piece of sandpaper.
19. Adjust the brakes, install the brake drum and wheel. Lower the vehicle and test drive.

Normally, remove tire, then just remove drum. Sometimes, for manufaturing purposes, they have some small copper colored clips on the studs that are used to keep the drum in place during shipping, before tires are mounted. You can remove these and discard.

Emergency brakes must not be set to remove drum, and sometimes you must work the drum back and forth to get it off. Also, can make it easier to remove if you adjust the brakes backwards, so they are not so tight.

u will need to deglaze the brakes remove pads and rub with sandpaper its just dirt making the noise

if you havent already tried them,try mettallic based pads

ok for the front brakes ,, change the pads if they need it and if there glazes you will have to get them machined by a machanic shop if u take them off you self and get them done when u put it all back togeather you will have to bleed them there is a nozzle behind the calapiers you pump the brakes 5 times and hold down and another person releases the nozzle to let all the air out repeat untill only fluid comes out both sides and be sure to check your brake lines for any cracks or leaks

-for the rears
if there discs reapeat as above
if there drums
take of the drum blow all the dust out be sure not to breath any in (quite poisin)
check the pads if buggered replace
check the inside of the drums (can also be machanied)
and check the wheel cyilinders if any is leaking
thats as much as i can help
if u do all that u should be fine
remember saftey first
