Replacement
1. Support the front wheels with chocks. Engage first gear (or position "P"). Loosen the rear wheel mounting nuts, lift the rear of the car and place it on supports. Remove the corresponding rear wheel.
2. Install a clamp on the brake hose going to the rear brake caliper. This is necessary to reduce fluid leaks during subsequent operations (see Fig. 9.2).
3. Loosen (without completely unscrewing) the brake hose nipple located on the caliper (see Fig. 9.3).
4. Remove the rear brake pads and release the caliper (paragraph 8).
5. Disconnect the handbrake cable from the caliper. On Sedan and Hatchback models, the handbrake cable lever is directed away from the caliper, and on Station Wagon models, it is directed towards the caliper (see Fig. 9.5,a,b).

6. Remove the cap. Unscrew the guide pin. Remove the caliper and place a support under it or tie it up so as not to stretch the hose (see Fig. 9.6, a-c).
7. Hold the caliper with one hand and use your other hand to hold the hose so that it does not turn. Turn the caliper relative to the hose and unscrew it from the fitting, being careful not to twist or pull the hose. Immediately after disconnecting the caliper, plug the holes in the caliper and hose so that no dust or dirt gets in.
8. If necessary, the caliper support bracket can be removed by unscrewing its bolts from the rear axle support.
Repair
9. At the time of writing, repair procedures were not provided. Therefore, before disassembling the caliper, inquire about the availability of spare parts. Basically, you can use the information regarding the repair of the front brake caliper. However, keep in mind that before pulling the piston out of the caliper, you will need to unscrew the piston from the handbrake mechanism (paragraph 8, item 10). When assembling, press the piston fully into the caliper and screw it onto the handbrake mechanism. Do not attempt to disassemble this mechanism if it is faulty. In this case, the caliper assembly must be replaced.
Installation
10. Install the caliper and support bracket (where necessary) in the reverse order of removal. Make sure the brake hose is not twisted. Tighten the mounting bolts and wheel nuts to the specified torque.
11. Remove air from the brake system (paragraph 15). Make sure there are no leaks in the hose connection. Check the brakes thoroughly before driving the vehicle.
