In a disc brake, the rear cables act on the brake pads through the drive lever, spreader bar, and adjuster.
The action of the parking brake should occur when the parking brake lever is set to the third tooth of the sector. When tightening the parking brake lever on the fourth tooth of the sector, the rear brakes should be locked.
On vehicles with rear disc brakes, the amount of idle travel of the parking brake lever depends on the functioning of the adjusting mechanism. However, in general, you can be guided by the following rule. If the parking brake lever travel is increased, then this is evidence of wear on the rear brake pads or the result of stretching of the drive cables.
As a rule, adjustment of the parking brake is only necessary when replacing the cable or rear brake pads.
Parking brake cable - replacement
1. Put the rear of the car on jack stands.
2. Release the parking brake.
3. Loosen the adjusting nut on the leveling bracket just enough so that the cable can be released.
4. Remove the brake drum and brake shoes. Disconnect the other end of the cable from the drive lever. For disc brakes, remove the cable sheath retaining clip and the cable clamp on the drive lever (see: illustration).
5. Release the drive cable from the various mountings on the rear suspension and underbody.
When installing the cable, do not forget to fix its sheath. Attaching the rear cable to the drum brake lever is a little difficult due to the presence of a coil spring.
6. Compress the coil spring with side cutters to release the end of the cable and secure it to the drive arm.
Attention! After replacing the parking brake cable of the disc brake, be sure to adjust the mechanism.
7. Adjust the parking brake. The parking brake must only be adjusted after repairing the parking brake mechanism and after replacing the brake pads.
8. Place the rear of the vehicle on jack stands.
9. Cars with drum brakes. Release the parking brake.
10. Turn off the adjusting nut to the very end of the thread of the cable end (see illustration).
11. Press a brake pedal against the stop.
12. Tighten the parking brake lever by two sector teeth.
13. Tighten the adjusting nut so that both wheels turn with difficulty by hand.
14. Release the parking brake lever and make sure both rear wheels turn freely.
15. Cars with disc brakes. Perform brake adjustment.
16. Tighten the parking brake cable adjusting nut so that both drive levers on the brake calipers of the left and right wheels move away from the stops. Ask an assistant to supervise this moment.
17. Loosen the adjusting nut two turns. To check the tension of the cables, move the drive lever of one of the brake mechanisms until it stops. If at the same time the drive lever on the second mechanism also moves to the stop, then the cables are too tight (see illustration).
18. Loosen the adjusting nut.
19. Tighten and then release the parking brake lever. Check how freely the rear wheels rotate.
