Note: Replace both sets of brake pads at the same time - never replace pads on only one wheel, this can cause uneven braking.
Place wedges under the front wheels, then raise the rear of the vehicle and secure it with stands under the axle.
Working from one side of the vehicle, remove the brake drum as instructed in the next section.
Note the location and direction of all components before disassembly.
Remove dust and dirt from the drum and brake pads, being careful not to inhale the dusty air.
Remove the brake shoe support pins, springs and support rings by pressing the rings and turning them 90°with pliers. that the support pins are removed through the brake pad platter (pic. 9 11. 9.12).
Disconnect the handbrake cable from the lever.
Upper and lower return springs can now be detached (remove the hooks) and remove the pads individually, or the pad assembly, the adjuster rod and springs can be removed together (see chapter 10). Take care not to damage the rubber boots of the wheel brake cylinders. Before removing the coupling springs, note the location of the springs and the adjusting mechanism
If the pads need to be temporarily removed, secure the wheel cylinder with a strong rubber band or spring clip to prevent the pistons from being pushed out of the bores. In any case, you must not press the brake pedal while removing the drum.
Remove dust and dirt from the brake pad platter, being careful not to inhale dusty air.
Apply some brake grease to the friction surfaces of the platter.
If friction brake linings are contaminated with brake fluid or grease, find the source of contamination before installing new friction linings (wheel brake cylinder or hub bearing seal leaking).
Although friction brake pads are purchased separately (without brake pads), preference is given to replacing brake pads along with friction linings.
Disassemble the brake pads, adjuster rod and remove the springs. Note the location of the parts.
When disassembling both brake mechanisms at the same time, try not to mix the parts. Parts are labeled to indicate left-hand and right-hand parts: the threaded rod is designated L and R (L - left and R - right), and on other parts, the left side is indicated in black, and in silver - the right-hand part.
Remove and remove dirt from the adjuster rod. Apply some silicone grease to the threads of the adjusting rod. If it is necessary to install new friction brake pads Z and pads, it is also necessary to replace the thermal clamp on the adjusting rod (pic. 9.13).
Check the tension springs. If they are defective or badly worn, it is recommended to replace them. Weak springs can cause the brakes to stick
Assembly assembly can be carried out in the form of an angle. Install the pads on the platter. Take care not to damage the rubber boots of the wheel cylinder or dislodge the pistons.
After installing the pads in place, insert the support pins and secure them with the springs with rings.
Install the handbrake cable, then install the bushing if necessary.
If the assembly is legal in the form of a node seems too difficult, then you can install the pads and secure them with support pins, then insert the adjusting rod and put the springs and adjusting mechanism.
Unscrew the fine adjustment knob to reduce the protrusion of the rod until the brake drum sits on the shoes.
Make sure that the handbrake lever is set correctly, that the finger is at the arch of the shoe. then install and secure the brake drum (pic. 9.14).
Repeat the brake operation on the other side of the vehicle.
Adjust the brakes by checking the foot brake about fifteen times. The drums will make a clicking sound when the automatic controls are activated. When the clicks stop. adjustment is completed.
Check the handbrake cable adjustment as indicated in the appropriate section below.
Install the wheels and lower the vehicle to the ground.
New brake pads should wear in gradually, so try to avoid hard braking during the first 100 miles.
