Replacing disc brake pads (Mitsubishi Galant 6)

Warning! Brake pads must be replaced simultaneously on both front/rear brake mechanisms. Remember that 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 and Galant models up to 1993.

Front wheel brakes

Removal

1. The design of the front wheel disc brake mechanism for Mirage and Galant models up to 1993 is shown in the illustration.

2. Pump out some of the fluid from the brake master cylinder reservoir. The reservoir should be emptied approximately halfway to provide a reserve volume for the level to rise when the pads are pressed out.

3. Loosen the front wheel nuts. Jack up the front of the car and place it on supports, set the parking brake/chock the rear wheels.

4. Remove the caliper guide pins and lift the caliper assembly off the brake mechanism anchor bracket. Tie the caliper in the raised position with wire, preventing it from hanging on the brake hose.

Note: On some models, the caliper can be locked in the raised position by removing only one of the guide pins, with the other acting as the pivot pin.

5. Remove the brake pads with spring clips and adjusting shims - try to remember the order of installation of the components.

6. To secure the brake disc to the hub assembly, screw a pair of wheel nuts onto the studs and tighten them loosely.

Installation

1. Using a large clamp, press the caliper piston into the cylinder (on two-cylinder calipers, both pistons should be depressed).

2. Lubricate the sliding bearing surfaces of the brake mechanism and install the replacement brake shoes, placing the adjusting shims and spring clips in the correct order. Lower the caliper onto the anchor bracket - try not to allow the protective cover to become pinched, make sure that the brake hose is not twisted.



3. Lubricate, install in their standard places and tighten the guides and locking pins.

4. Install the wheel and lower the car to the ground.

5. Check the efficiency of the brake system - before starting road tests, press the foot brake pedal several times to settle the components and increase the pressure in the hydraulic system.

Rear wheel brakes

Removal

1. The design of the rear wheel disc brakes on Mirage and Galant models up to 1993 is shown in the illustration.

(The article is based on data from the website: mitsubishiman.ru)

2. Pump out approximately 2/3 of the brake fluid from the master cylinder reservoir - when the piston is pressed down, the fluid may begin to be forced out of the reservoir.

3. Jack up the car and place it on supports.

4. Remove the corresponding rear wheel.

5. Release the parking brake.

6. Disconnect the parking brake drive cable from the brake mechanism assembly.

7. Remove the lower guide pin, lift the caliper assembly up and tie it in this position.

8. Remove the outer adjusting shim, brake shoes and spring clips - try to remember the installation position of the components.

9. To secure the brake disc to the hub assembly, screw a pair of wheel nuts onto the studs and tighten them loosely.

Installation

1. Rotate the caliper clockwise using special tool No. MB9f52, and press it into your cylinder.

2. Lubricate the sliding bearing surfaces of the brake mechanism and install the replacement brake shoes, placing the adjusting shims and spring clips in the correct order.



3. Lower the caliper onto the anchor bracket - try not to allow the protective cover to become pinched, make sure that the brake hose is not twisted.

4. Lubricate, install in its original place and tighten the lower guide pin.

5. Install the wheel and lower the car to the ground.

6. Check the efficiency of the brake system - before starting road tests, press the foot brake pedal several times to settle the components and increase the pressure in the hydraulic system.

Diamante and Galant models since 1994.

Braking mechanisms of the front and rear wheels

Note: Since the rear disc brakes on these models are not equipped with a parking brake drive, they are no different in design from the front ones and are considered together.

Removal

1. The design of disc brakes on Diamante and Galant models since 1994 is shown in the illustrations.

2. Pump out approximately 2/3 of the brake fluid from the master cylinder reservoir - when the piston is pressed down, the fluid may begin to be forced out of the reservoir.

3. Jack up the car and place it on supports.

4. Remove the appropriate wheel.



5. Remove the guide and locking pins, then remove the caliper from the anchor bracket and tie it up with wire, avoiding tension on the flexible brake hose.

Note: On some models, the caliper can be locked in the raised position by leaving it in place and using the top pin as a pivot.

6. Remove the brake pads with spring clips and adjusting shims - try to remember the order of installation of the components.


7. To secure the brake disc to the hub assembly, screw a pair of wheel nuts onto the studs and tighten them loosely.

Installation

1. Using a special device or a large clamp, press the caliper piston into the cylinder.



2. Lubricate the sliding bearing surfaces of the brake mechanism and install the replacement brake shoes, placing the adjusting shims and spring clips in the correct order. Lower the caliper onto the anchor bracket - try not to allow the protective cover to become pinched, make sure that the brake hose is not twisted.





3. Lubricate, install in their regular places and tighten the guide and locking pins. The tightening force of the guide and locking pins is 75 N·m for the front brake mechanisms and 27 N·m for the rear ones.


4. Install the wheel and lower the car to the ground.

5. Check the efficiency of the brake system - before starting road tests, press the foot brake pedal several times to settle the components and increase the pressure in the hydraulic system.
