Removal and installation of parking brake pads
Withdrawal
Remove the rear brake disc.
Unhook the front return spring with the special clip. Check the spring. Replace a corroded or stretched spring.
1 - cable in the shell;
2 - bolt;
3 - support;
4 - brake shoe;
5 - spacer;
6 - finger;
7 - adjusting bolt;
8 - upper coupling spring;
9 - lower coupling spring;
10 - pressure spring;
11 - fastening pin.
Slightly press the mounting spring with a 5 mm hex wrench, turn it 90°and remove the spring from the brake shoe.
Remove the other shoe retaining spring in the same way.
Separate the brake pads at the top and remove them down.
Check the spacer for ease of movement and, if necessary, remove it.
Installation
Always change pads on two wheels at the same time.
Lubricate the contact surfaces and the spacer pin with a thin layer of grease.
Hook the spacer with the pin at the top to the parking brake cable.
Ensure that the brake shoe adjuster moves smoothly by lubricating the threads with a thin layer of molybdenum grease and turning the threaded connection.
Insert the shoe adjuster at the bottom between the shoes. Attach return spring (more subtle) down to the decks.
Insert brake pads. At the top, the pads should fit into the recesses of the strut.
Press the two brake pad retaining springs with a 5 mm Allen wrench while turning 90°at the same time. When installed, the mark on the bolt head must be aligned with the axis of rotation of the wheel.
Clamp the top shoe return spring.
The brake pads must be in contact with the pad support.
Install the brake disc and rear wheel.
Adjust the parking brake.
Attention: If the parking brake pads have been replaced, they must be run in on an empty road as follows: drive at a speed of 40 km/h and carefully apply the parking brake until light braking begins. While maintaining speed, apply the parking brake one click and drive for about 400 m. Release the parking brake and allow it to cool. It is recommended to carry out this running-in process about 4 times a year, regardless of the replacement of the pads, since in this way corrosion can be removed and compensated for from the nose of the pads.
Parking brake adjustment
The parking brake is completely independent of the main braking system. Because of this, the parking brake wears out much less. Due to corrosion of the brake drum or soiling of the pads, the friction efficiency is reduced. If old pads are adjusted, then for this you need to run in the parking brake.
The parking brake adjustment is necessary in the following cases:
- replacement of parking brake pads;
- replacement of brake drums; rearrangement of the adjusting device;
- too much lever travel (more than 10 clicks).
1 - parking brake lever;
2 - casing;
3 - locknut;
4 - adjusting nut;
5 — a bolt with a six-sided head;
6 — the switch of a control lamp of a parking brake;
7 - parking brake cable;
8 - clamping clamp;
9 — parking brake cable holder;
10 - tip.
Attention: The parking brake cables and any damaged parts of the parking brake must move easily.
Loosen one wheel bolt on both rear wheels.
Raise and support the vehicle from behind.
Pull off the parking brake lever cover at the top and pull it off.
Attention: The workshop uses a special tool to adjust the parking brake. It includes two socket wrenches inside each other that can fit a variety of locknuts and adjusting nuts. If there is no such device, then remove the cover from the parking brake lever, if necessary, remove the center console.
Remove the parking brake lever cover. To do this, loosen the screws after removing the protective caps. To remove the cover, pull it back from the top side towards the driver's seat and remove it.
Loosen the two locknuts and adjusting bolts (arrows) parking brake cable. Loosen the cables completely.
Completely remove one wheel bolt on each wheel. Rotate the wheel until the bolt hole is pointing straight down. Shine a flashlight into the bolt hole: the adjusting nut should be visible.
Note: The wheel does not need to be removed.
Turning the wheel of the adjusting nut with a screwdriver, install the parking brake pads so that the wheel cannot be turned by hand. Then turn the adjusting nut back 8 teeth. If the adjusting nut on the left side of the vehicle rotates in the direction «down», then the brake pads will lie against the drum. On the right side, you need to rotate the nut in the opposite direction to achieve the same effect.
After adjustment, check that the wheels turn freely, if necessary, turn the adjusting nut back a little more. The wheels must in any case turn freely.
Adjust the parking brake cable. To do this, tighten the parking brake lever 4 clicks (prong) and screw the adjusting nuts onto the cable so that both rear wheels can still be turned by hand with the same amount of force. Release the parking brake lever and check that the wheels turn freely. Repeat the adjustment if necessary.
Fully release the parking brake lever.
Turn on the ignition. The parking brake indicator lamp should not light up.
Tighten the parking brake lever one click. There must be no braking action on the rear wheels, otherwise the parking brake adjustment must be repeated. The parking brake warning light may come on.
Tighten the parking brake lever two clicks. The control lamp should now light up, otherwise bend the contact for the switch on the parking brake lever.
Switch off the ignition.
Tighten the locknuts while holding the adjusting nuts.
Insert the side cover of the parking brake lever and fix it with screws. Insert the screw covers.
Attach the parking brake lever front cover at the bottom and insert it at the top.
Lower the car.
Tighten the two rear wheel bolts to 100 Nm.
Removal and installation of the parking brake lever
Withdrawal
Remove the center (middle) console.
Completely unscrew the locknuts and adjusting nuts of the parking brake cable.
Pull the wire from the parking brake warning light switch.
Turn off bolts of fastening of the lever of a lay brake and take out the lever.
Installation
Insert the parking brake cable into the parking brake lever, install the lever and secure it with bolts.
Tighten the parking brake cable nuts by hand.
Adjust the parking brake.
Turn on the ignition. The parking brake warning lamp should go out when the parking brake is released. If not, adjust the parking brake warning light switch.
Install the center console.
