Malfunctions of brake pads
excessive wear or damage to the pads;
cracking of pad friction surface;
deep scratches and chips on the linings;
uneven wear of the brake pads;
deformation of the part.
Symptoms of brake pads failure
significant deterioration in braking performance;
increase of braking distance;
rattling, whistling or grinding during braking;
violation of the vehicle path during braking;
wobbling or vibration during braking;
unstable operation of the brakes;
appearance of projecting rim out of the pad friction material.
Causes of brake pads malfunctions
wear of the brake disc;
increase in the gap between the brake shoe and the drum;
foreign objects or dirt getting on the friction linings;
getting oil on the surface of the pad;
aggressive driving style;
the use of low-quality components and consumables;
failure of the brake cylinders;
incorrect installation of brake pads;
installation of improper type parts.
Diagnostics
For a DIY diagnosis it is necessary to measure the thickness and analyze the structural condition of brake pads. Minimum permissible thickness of the brake lining is 2 mm. The pad surface should be smooth, with no chips or cracks. In addition, its wear should be uniform.
You can also analyze braking process. Accelerate the vehicle to a speed of 60-80 km/h on a flat and dry road and stop it. In normal conditions the braking distance must be even. The absence of grinding or whistling in brakes is also a good sign.
A full inspection of the brake pads at a service station should be carried out every 10 000-15 000 kilometers.
Repair and replacement of brake pads
Brake pads repair is now irrelevant. Of course, the service station mechanics can replace the pad friction linings, but this type of repair work will not be much cheaper than buying and installing a new part. Furthermore, the recovered pads will have a sservice life considerably shorter than the new ones.
Replacing brake pads is a very important process, so it is strongly recommended to entrust it to professionals. Do not exceed the operation terms of the mechanism. It is necessary to replace the brake pads after 15 000-20 000 kilometers.
