If the brake pads need to be replaced, always replace the pads as a set for both wheels of the same vehicle axle.
Check both edges of the friction lining of the brake shoe (3). More wear is usually seen on the trailing edge of the brake pad.
Check brake pad thickness (3), to make sure that the wear of all brake pads on both wheels of the same vehicle axle is approximately the same.
Both front and rear brake pads have built-in wear indicators (1). When the brake pad wears to the limit value, the indicator begins to contact the brake disc (2), while a high-pitched squealing sound begins to be emitted during wheel rotation, signaling the need to replace the brake pads.
Brake pads must be replaced when the friction lining (3) wears down to a thickness of 2 mm from the bearing surface.
Remove the brake caliper and check the friction surfaces of the inner and outer brake pads to make sure they are parallel. Fold the brake pads with the friction surfaces facing each other and measure the clearance between the surfaces. If the gap is greater than 0.13 mm along the length of the friction lining, replace the brake pads with new ones.
Check that the brake pads are in place and not damaged or excessively corroded. If gaskets are missing or damaged, install new ones to ensure proper brake function.
Replace the brake pads with new ones if the friction linings of the pads have separated from the base plates.
Check the brake pads for cracks, cracks, or damage that could cause abnormal noise or otherwise impair brake performance.
