To mark the provision of a disk of a wheel concerning a nave that the balanced wheel could be established on the former place. To weaken wheel bolts.
To lift the car, to remove wheels.
To visually check thickness of brake slips — without the main metal plate — in front via the brake piston case. In case of doubt to remove brake shoes and to measure thickness by a caliper.
The limit of wear of brake shoes of disk brakes is reached when the slip has thickness of 1 mm (to 9/89 g of the issue) or 2mm (from 10/89 g of the issue). Value belongs only to a slip without the basis.
If the limit of wear, brake shoes is reached to replace. It is obligatory to replace all blocks on one axis.
By the unspoken rule of 1 mm of thickness of a brake shoe corresponds to distance of 1000 km. This rule belongs to severe conditions of operation. Under normal conditions blocks serve much longer. At a thickness of a brake overlay of a disk brake of 5,0 mm (apart from a back plate) its resource makes at least 4000 more km.
To establish wheels, considering at the same time a tag on a nave, to lower the car and to tighten wheel nuts cross-wise with effort of 100 Nanometers.
To establish back wheels, considering tags on naves. To lower the car and to tighten nuts of wheels cross-wise with effort of 100 Nanometers.
Visual check of brake pipelines
PERFORMANCE ORDER
To lift the car.
To clear brake pipelines a cold cleaner.
For protection against corrosion brake pipelines are covered with a polymeric layer. Damage of this layer can lead to corrosion of pipelines. Therefore brake pipelines should not be cleared by a wire brush, a skin or the screw-driver.
To check pipelines from the main thing brake to wheel brake cylinders by means of a lamp. The main brake cylinder is in a motive compartment under a compensation tank with brake fluid.
Brake pipelines should not be neither are bent, nor flattened. Also they should not have rusty or shabby places. Otherwise the pipeline should be replaced to the following junction.
Brake hoses connect brake pipelines to wheel cylinders on mobile details of the car. They are made of high-strength material, however over time can crack to fray or be cut about sharp objects. In this case they should be replaced.
To bend brake hoses here and there and to check for existence of damages. Hoses should not be overwound, pay attention to color lines if those are available.
To turn a steering wheel here and there. Brake hoses should not concern at the same time details of the car in any situation.
Junctions of brake pipelines and hoses should not be damp because of the acting brake fluid.
If a compensation tank and laying damp because of brake fluid, it is not obligatory the instruction on the faulty main brake cylinder. Most often brake fluid acts through an opening or laying of a cover of a compensation tank.
