Warning! Remember that the dust generated during operation of the brake mechanisms may contain asbestos, which is extremely harmful to human health. Never blow off dust with compressed air or inhale it - wear a protective mask or respirator when servicing the mechanisms. Never use gasoline or petroleum-based solvents to wipe brake system components - use only branded cleaning agents or methyl alcohol!
Mirage models produced up to 1992.
Removal
1. The design of the drum brake mechanism used on Mirage models up to 1992 is shown in the illustration.
2. Jack up the car and place it on supports.
3. Remove the corresponding rear wheel.
4. Remove the hub nut dust cover.
5. Remove the self-locking hub nut.
6. Remove the outer wheel bearing.
7. Remove the brake drum assembly with the inner wheel bearing from the spindle.
8. Remove the oil seal.
Installation
1. To check the suitability of the self-locking nut for further use, screw it onto the spindle so that the end of the latter protrudes outward by approximately 3 mm. Measure the torque of resistance to counterclockwise rotation of the nut. The measurement result is less than 5.5 N·m, the nut must be replaced.
2. Lubricate and install the inner bearing.
3. Install the new oil seal.
4. Place the brake drum on the spindle.
5. Lubricate and install the outer wheel bearing.
6. Tighten the self-locking hub nut to the required torque (150÷200 Nm).
7. Install the protective cover.
Checking the status
1. Measure the inner diameter of the brake drum removed from the vehicle - in order to identify signs of ovality, the measurement should be taken at several points.
2. If the measurement result exceeds the maximum permissible value (231 mm), replace the drum complete with shoes (see Section Removal and installation brake shoes).
Galant and Mirage models since 1993.
Removal
1. The design of the drum brake mechanism used on Galant and Mirage models since 1993 is shown in the illustration.
2. Jack up the car and place it on supports.
3. Remove the corresponding rear wheel.
4. Loosen the parking brake actuator adjusting nut.
5. Pull the brake drum off the hub assembly - if necessary, tap the assembly with a soft-faced hammer to loosen it. If the disc is stuck and cannot be removed, screw a pair of bolts of the appropriate size into the two specially provided threaded holes in its front surface and, gradually tightening them, loosen the drum.
Installation
1. Install the drum onto the hub.
2. Install the wheel and adjust the parking brake drive.
3. Lower the vehicle to the ground.
