Warning! Remember that the dust produced during the 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 mechanisms. Never use gasoline or petroleum-based solvents to clean brake system components - use only branded cleaners or methyl alcohol!
Note. Both brake calipers on the same axle must be changed at the same time. Be aware that remanufactured brake caliper assemblies can always be ordered from Mitsubishi Authorized Service Stations on an exchange basis.
Mirage and Galant models through 1993 issue.
Front wheel brakes
Removing
1. Loosen the front wheel nuts. Jack up the front of the car and place it on jack stands. Set the parking brake/chock the wheels on the ground.
2. Remove wheels.
3. In order to prevent excessive lowering of the GTZ brake fluid level, remove the cap from the tank, cover the neck with plastic wrap and screw the cap back on.
4. Caliper installation details are shown in the illustration.
5. Disconnect the flexible brake hose first from the metal line, then from the caliper (use two wrenches when loosening the union nuts - see Section Removal and installation of brake lines).
6. Remove the guide and blocking fingers of the caliper.
7. Remove the caliper assembly from the anchor bracket.
Installation
1. If the removed caliper is to be used further, thoroughly wash it in a special cleaning liquid - in no case do not use kerosene and other petroleum products to wash the components of the brake mechanism! Carefully check the condition of the caliper, if necessary, replace it.
2. Establish a support on the regular place and tighten directing and blocking bolts with the demanded effort.
3. Connect the brake hose to the caliper - do not forget to replace the sealing washers and make sure that the hose is not twisted.
4. Bleed the appropriate brake circuit (see Section Bleeding the brake system).
5. Replace the wheels, lower the vehicle to the ground. Before starting the operation of the vehicle, make sure that the braking system is working properly.
Rear wheel brakes
Removing
1. Disconnect the negative cable from the battery.
Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to activate the audio system!
2. Jack up the car and put it on stands.
3. Remove rear wheels.
4. Release the parking brake.
5. Remove the retainer and disconnect the parking brake cable from the brake assembly to be serviced.
6. In order to prevent excessive lowering of the GTZ brake fluid level, remove the cap from the tank, cover the neck with plastic wrap and screw the cap back on.
7. Caliper installation details are shown in the illustration.
8. On front wheel drive models (FWD) unscrew the hollow bolt of the union connection and disconnect the flexible hose from the brake caliper.
9. On all-wheel drive models (AWD) first disconnect the brake hose from the metal line, then from the caliper (use two wrenches when loosening the union nuts - see Section Removal and installation of brake lines).
10. Remove the locking pin and remove the caliper from the anchor bracket.
Installation
1. On FWD models, connect a brake hose to the caliper - do not forget to replace the sealing washers of the hollow bolt of the union connection. Fix the hose in the support bracket.
2. On AWD models, connect the hose to the caliper and tighten the union nut to the required torque (13÷17 Nm). Next, fix the hose in the support bracket and connect it to the steel tube - the required tightening torque of the union nut is again 13÷17 Nm.
3. Make sure that the flexible brake hose is not twisted during connection.
4. Install the caliper on the anchor bracket of the brake mechanism, making sure that the locking groove is correctly aligned with the protrusion of the shoe.
5. After lubricating, screw in the locking pin and tighten it to the required torque (32 Nm).
6. Bleed the appropriate circuit of the brake system (see Section Bleeding the brake system).
7. Inspect hydraulic lines for signs of leak development.
8. Replace the wheels, lower the car to the ground. Before starting the operation of the vehicle, make sure that the braking system is working properly.
Models Diamante and Galant since 1994 vol.
Front and rear brakes
Note. Due to the fact that on these models the rear wheel disc brakes are not equipped with a parking brake drive, they do not differ in design from the front wheels and are considered together.
Removing
1. Jack up the car and put it on stands.
2. Remove the relevant wheel.
3. Turn out a hollow bolt of the union socket and disconnect a brake hose from a support. Connectors with union nuts are used to fasten the hose, use two wrenches and disconnect the hose first from the metal line and only then from the caliper. Seal the open end of the hydraulic line immediately.
Attention! Try not to allow the liquid level in the GTZ reservoir to drop excessively, as this will entail the need to pump the entire brake path.

4. Turn out directing and blocking bolts of a support and remove the last from an anchor bracket of the brake mechanism.
 |  |
Installation
1. Lower the caliper onto the anchor bracket.
2. Screw in the guide and blocking bolts and tighten them to the required torque (32 Nm).
3. Install/connect flexible brake hose to caliper (if equipped, do not forget to replace the sealing washers of the hollow bolt of the in-line connector). Make sure the hose is not kinked.
4. Bleed the appropriate hydraulic circuit (see Section Bleeding the brake system).
5. Depress the foot brake pedal and check the system for signs of leaks.
6. Replace the wheels, lower the car to the ground. Tighten the wheel nuts to the required torque (120÷140 Nm).
7. Before starting the operation of the vehicle, make sure that the brake system is functioning properly.
