I have a 2005 chevy avalanche z71,I need to replace the brake shoes on the parking brake,it has rear discs with the drum inside.Do I have to remove the rear axle to get the new shoes on,they are one piece

It could be the springs inside the drum, could be rusted and stuck or broke, take your tire off and pull your brake drums

Removal
1.Remove rear wheel and tire assembly from vehicle.

2.Remove rear brake drums from hub and bearing assemblies after loosening the two brake drum screws.

3.Be sure that the parking brake pedal is in the release(most upward) position.

4.Completely loosen square nut of the rear parking brake cable. Then create slack in the rear parking brake cables.

5.Remove adjuster spring from adjust lever and brake shoe.

6.Remove adjust lever and turn the adjusting wheel of adjuster assembly to the direction of the arrow as shown.

7.Remove the strut spring and the lower retracting spring from the brake shoe.

8.Remove the upper return spring from the brake shoe.

9.Remove brake back plate hold down spring and pin from the leading brake shoe assembly.

10.Remove the leading brake shoe. Then remove the adjuster assembly, strut and anchor spring from the trailing brake shoe.

11.Remove the trailing brake shoe from the brake back plate after removing hold down spring and pin.

12.Remove the trailing brake shoe from the rear parking cable.

13.Remove parking pivot lever from the leading brake shoe.

Replacement
1.Lubricate the eight shoe contact areas on the back plate and anchor.

2.Install the trailing brake shoe to the rear parking cable.

3.Install trailing brake shoe on brake back plate and install the trailing brake shoe hold down spring and pin on the brake shoe.

4.Tighten the square nut of rear parking cable.

6.Install leading brake shoe on brake back plate.

7.Install the brake shoe upper return spring, strut spring and the lower retracting spring to the brake shoe.

8.Properly rotate the adjusting wheel of adjuster assembly to the direction of the arrow in as shown.

9.Install the adjuster spring on the adjust lever and leading brake shoe assembly.

10.Install the leading brake shoe hold down spring and pin on the brake shoe.

11.Adjust brake shoes assemblies so as not to interfere with brake drum installation.

12.Install the rear brake drums on the hubs.

13.Check and adjust whether the pedal stroke in the specification.(Refer to section BR Gr./On-vehicle service/Pedal stroke of parking brake)

14.Install wheel and tire.

15.Push the parking brake pedal to the floor once and release pedal. This will automatically remove the slack from and correctly adjust the parking brake cables.

16.Test the vehiche on the road. The adjust will continue the brake adjustment during the road test of vehicle.

Inspection
1.Inspect the disassembled parts for wear, rust or damage.

2.Measure the thickness of brake shoe lining.
Standard : 0.17 in (4.5 mm)
Minimum : 0.04 in (1 mm)

3.If the shoe lining is less than minimum or shows signs of uneven wear, replace new one.

4.Measure the inside diameter of the brake drum.
Standard : 10 in (254 mm)
Maximum : 10.07 in (256 mm)

5.If the inside diameter of the brake drum is more than maximum or shows signs of uneven wear, replace new one.

6.Inspect the lining and drum for proper contact. If the contact condition is improper, repair it with a grinder or replace the brake shoe assembly.

Your Buick has front disc brakes...and rear drum brakes...the usual concern is the front pads as they are used more...these are the easiest pads to replace...as you only need to remove the caliper from the rotor with 2 bolts to lift off...Be sure to push the piston all the way back into the caliper to install new pads...rotors are pop offs too...The rear drum is different...the brake shoes are held on with clips and springs...try keeping one of the shoe assemblies intact while you switch out the other shoes...be sure to inspect the rear wheel brake cylinders for possible leaking...usually an oil build up inside the brake drum...these are inexpensive and should be switched out on a 93 Buick...:) Hope this helps.

Hi, this is not a terrible job, but you are correct, the axles need to be removed, After this, you remove the park brake shoe, cable, and hardware.Unbolt the shield, swap over park brake stuff, and reassemble. Not extremely har, but is a b it time consuming. Good luck...Coop

This is a big job for such a small part. I suggest you repair/replace rotors, pads, and anything else back there while you are at it. You will need to remove both wheels on both sides, as well as the axles (I think). See my earlier post on Rear Rotor removal to see how this is done.

You will need a large spindle nut to remove the axles.

DISASSEMBLY:
Once you have access to the parking brakes inside the rotor hat:
1. Lock out the parking brake w/a pair of Vise grips (on the parking brake cable under the cab)
2. Disengage teh park brake cable from behind the rotor assembly to allow easier disassembly of the parking brake shoes.
3. Disassemble the rear park brake shoes.

REASSEMBLY:
1. Reassemble the rear parking brake shoes. This is a typical, small brake drum configuration. Do one side at a time - so you can see how to reassemble each small part. Keep the springs and parts oriented the same: front to front and interior to interior, etc.
2. Release the parking brake cable
3. Install the disc brake rotor(s)
4. Install the disc brake caliper(s)
5. Install tire & wheel assembly
6. Lower the vehicle

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

parking brake shoes may be stuck. it will have to be taken apart and checked

how do i remove back brake shoes on a 2005 chevy z71

Well with the rotors on the rear you still have a drum with brake shoes in the middle for your E-Brake.Think you have to back off the parking brake nut at the equalizer(one cable into two) to get slack in the cable to back off the shoes inside.Well hope this helped and good luck.

Hello;
The parking brake cables may be stretched and in need of adjustment. Follow the cables along to a nut. Then you can tighten the adjusters up on both sides until you have the proper tension. Also make certain none of the brackets are bent or broken that the cables ride through.
Thanks;
