Checking the thickness of brake pads (Mitsubishi Lancer 3)

Disc brakes

Mark the position of the wheel disk on the wheel hub with paint. This ensures that the balanced wheel can be reinstalled in its original position.
Raise the car, remove the wheels.

Inspect the brake lining thickness - without the back metal plate - through the hole in the brake caliper.
If in doubt, remove the brake pads and measure the thickness of the brake linings.
The maximum permissible brake lining thickness (wear limit) is 2.0 mm (excluding the thickness of the carrier plate). On cars with 1.2/1.5 l engines produced from 1.84 to 8.88, the wear limit is 1.0 mm.
When the wear limit is reached, the brake pad is replaced. It is necessary to replace all pads on one axle at the same time.

Note: According to a rough estimate, the brake pad wears out by 1 mm over a mileage of at least 1,000 km. This estimate is given for unfavorable operating conditions. Under normal operating conditions, the pads last longer. With a disc brake pad thickness of 5.0 mm (taking into account the thickness of the back plate), the remaining service life of the brake pad is at least another 3,000 km.

Install the wheels, observing the markings made in relation to the hubs and tighten the wheel nuts crosswise: tightening force see item 19.4.

Drum brakes

Raise the car from behind, see item 29.
If the brake shields have an inspection hole, remove the rubber cap from the inspection hole and shine a portable light into the hole. The wear limit is 1.0 mm (excluding the thickness of the board).
If there is no inspection hole or there are any doubts, remove the brake drum.
Measure the thickness of the pad at the most worn place.
When the wear limit of 1 mm is reached, the brake pad is replaced. It is necessary to replace all pads on one axle at the same time.

When removing the brake drum, pull back the wheel brake cylinder cuffs and check if there is any moisture there. If there is moisture, replace the brake cylinder.
