....and a special key «at 13» for pipeline nuts.
If during operation there are leaks of brake fluid on the brake drum and the inner side of the wheel, or if the pistons in the cylinder are jammed, replace the working cylinder.
1. Loosen the rear wheel nuts on the side of the cylinder being replaced, place wheel chocks under the front wheels («shoes»). Engage 1st gear in a manual transmission or set the automatic transmission control selector lever to position «R» (parking). Raise the rear of the vehicle using a jack and secure it on jack stands.
2. Check that the parking brake lever is pushed all the way down (the car is disinhibited).
3. Remove the rear wheel.
4. Remove the brake drum (see «Removal and installation of a brake drum»).
5. Remove the brake pads (see «Replacing the brake pads of the brake mechanism of the rear wheel»).
6. Clear the place of fastening of a brake tube and bolts of fastening of the working cylinder from a back side of a brake board from dirt.
7. Turn away a nut of fastening of a brake tube to the working cylinder...
8.... slide the nut along the pipeline, disconnect the tube and plug its hole, for example, with an air release valve cap.
GOOD ADVICE: After a long period of use, the brake tube nut «grows together» with the tube into a single unit, so when you try to unscrew the nut, the tube twists and breaks. In this case, just loosen the tube nut a little, then unscrew the cylinder mounting bolts and disconnect it from the tube by screwing the cylinder from its nut. After disconnecting the cylinder from the tube, the mobility of the released nut can be restored by moistening it with brake fluid and turning the nut alternately in both directions with a wrench.
9. Loosen the two bolts securing the working cylinder to the brake shield...
10.... turn out the bolts, holding the cylinder on the other side...
11.... and remove the working cylinder.
NOTE: Pay attention to marking of the working cylinder. To replace, purchase a cylinder with the same marking.
12. If there is no protective cap on the air release valve of the new cylinder, remove it from the old valve.
13. Establish the working cylinder in an order, the return to removal.
14. Install brake pads.
15. Install the brake drum.
16. Remove air from the brake system (see «Bleeding the hydraulic drive of the brake system»).
17. Press the brake pedal sharply several times to bring the brake shoes to the drum.
