Inspection.
1. Proceed as indicated in paragraphs 1 and 2 Section 9.
2. Block the front wheels and shift into gear. Loosen the rear wheel nuts on the working side, then jack up the rear of the car and remove the wheel. Release the handbrake.
3. Remove the brake drum mounting screw and remove the drum. If it is tight, release the brake shoes by removing the plug in the rear brake plate and pushing the handbrake control lever outward using a screwdriver (Pic. 9.27).

4. Remove the studs and rings or springs and spacers. Replace them if they are damaged (photo).

5. Disconnect the handbrake cable from the control lever (photo). If there is not enough slack in the cable, disconnect it near the equalizer.

6. The return springs can now be unhooked and the shoes removed individually, or the shoe assembly, spacer and springs can be removed as a whole. The second way is especially easy if the rear hub is removed, as was done for the purpose of obtaining photographs. Be careful not to damage the rubber cylinder wraps.
7. Clean the rear brake plate without inhaling the powder or spraying it into the air. (Original liners are now manufactured without asbestos, but this may not be the case with other liners.)
8. Identify and correct the source of pad contamination before installing new shoes.
9. Disassemble the shoes, spacer and springs. Pay attention to how the springs are installed and how the spacer is positioned. Do not confuse left- and right-hand parts: on all models except models type "station wagon" the threaded rod is marked "L" or "R", and other components of this kind are color coded - "black" for left side and color code "silver" - for the right side (photo).

10. Disassemble and clean the adjusting spacer. Lubricate the threads with silicone-based lubricant.
11. If a new handbrake shoe lever was not supplied with the new shoes, use the old one. It may be secured with a pin and a snap ring (photo), or a rivet that will need to be drilled out.

12. Assemble new shoes, springs and adjustment components. Place the return springs in their holes in the new shoes and place the self-adjusting components. The threaded spacer should be clean and lightly lubricated and fully retracted using the sprocket wheel before installing it between the shoes. Note that the shorter fork leg of the spacer should be facing you. For models with a closed body ("salon") and with an upward opening rear door ("hatchback") it is necessary to replace the spring securing the adjustment lever pin to the shoe web. Refer to the corresponding accompanying photos for assembly questions.

13. Before installing the brake shoe assemblies into place, lubricate the shoe friction areas on the rear brake plate with a copper-based anti-seize compound.
14. Place the shoes on the rear brake plate. Be careful not to damage the cylinder wrappings or dislodge the pistons. When the shoes are in place, insert and secure the studs. Reconnect the handbrake cable and install and adjust the hub if it was removed (photo).

15. If you find it very difficult to install the shoes and springs together, it is possible to install the shoes and secure them with studs, then leave the adjusting spacer and install the springs and adjusting lever.
16. Push back the adjusting gear to reduce the length of the spacer until the brake drum sits above the new shims. make sure the handbrake lever is positioned correctly (the pin is on the edge of the shoe web, not on top of it). Install and secure the brake drum.
17. Repeat these operations with the other rear brake, then adjust the brakes by pressing the foot brake (models "salon" And "hatchback") or handbrake (model "station wagon") at least ten times. A clicking sound will be heard indicating the operation of automatic regulators; when it stops, the setup is complete.
18. Check the handbrake setting and adjust it if necessary (Section 26).
19. After installing new pads, avoid heavy braking for several hundred miles to allow the pads to break in.
