Checks of brake system
Signs of malfunctions in brake system 1 Disk brake mechanisms can have the built-in indicators of wear of frictional slips which signal that wear of slips reached critical size. Thus slips should be changed immediately, differently brake disks will be damaged and they will need expensive repair. By 2 Liouba from listed below signs can point to potential defect of brake system: a) When squeezing a pedal of a brake the car "withdraws" in one party b) Brake mechanisms when braking publish scraping or squealing sounds c) The pedal of a brake has an excessive course d) The pedal of a brake pulses (it normally only at ABS system work) e) Leakages of brake liquid (usually on tire or wheel inside) are observed 3 in case of detection at least one of these signs immediately examine brake system. Brake lines and hoses
4 Park the car on an equal platform and switch off the engine. Remove caps from wheels. Weaken, but do not remove bolts of fastening of all four wheels. To 5 Poddomkratta the car and reliably establish it on support. 6 Remove wheels (address to the Section Rotation and replacement of wheels). 7 Check all brake lines and hoses on existence of cracks and attritions in their external covering, leaks, swellings and deformations. Check brake hoses in forward and back parts of the car on existence of signs of a softening, cracks, deformations or wear as a result of a friction about other components. Check all shtutserny connections on existence of signs of leaks and make sure of reliability of fastening of all bolts and clips of brake hoses.
9 Turn a steering wheel to the right and to the left against the stop. Hoses should not touch elements of a design of the car thus. 10 At detection of leakages of liquid or their damages it is necessary to eliminate immediately. For more detailed description of procedure of repair of brake system address to Head Brake system. Check of thickness of brake shoes At wear of brake shoes of lobbies and back brakes on the dashboard the signaling device lights up. Thus it is necessary to replace brake shoes urgently.
11 Mark paint the provision of wheels concerning a nave. It will allow to establish at assembly otbalansirovanny wheels in their former situation. Weaken bolts of fastening of wheels on the car standing on the earth. Lift the car, put it on supports and remove wheels. Disk brake mechanisms
14 In doubtful cases remove blocks and measure thickness by a calliper. At achievement of a limit of wear of a block it is necessary to replace. Thus it is necessary to replace all four blocks of one axis even if the limit of wear was reached by only one block.
15 Check, whether has a support of traces of leakages of brake liquid. In the presence of a leakage urgently hand over a support in repair. 16 Visually check brake disks from the internal and external parties on existence задиров, corrosion damages and cracks. If necessary replace disks. Parking brake
18 If a limit of wear will reach, it is necessary to replace blocks. Surely replace all blocks of one axis, address to the Section Removal and installation of blocks of the parking brake. 19 Establish wheels so that the markings put at removal coincided. Previously grease with a thin layer of bearing greasing aligning belt of a disk of a wheel on a nave. Bolts of fastening of a wheel do not grease. It is necessary to replace rusty bolts. Establish wheels and wrap fastening bolts. Lower the car on wheels and tighten bolts cross-wise the moment of 100 N • m. Check of functioning of the parking brake The parking brake represents a drum-type brake with a hummock drive. The drum is built in disks of a back brake. As wear of a brake shoe of the parking brake is insignificant, corrosion damage or pollution of brake shoes can take place. Therefore before check of the parking brake it is recommended to earn extra it as follows: 20 Smoothly brake the car the parking brake since speed of 40 km/h on the desert street or a parking platform so. Without changing speed, tighten the parking brake on one tooth and pass 400 more m. Release a brake and let's to it be cooled.
21 Lift and establish on supports a back part of the car. Wheels should be over the earth at height not less than 2 see. 22 Tighten the parking brake on one click and turn back wheels. Wheels should be turned freely, brakes should not work. 23 When raising brake on 10 clicks of a wheel should затормаживаться completely. 24 Otherwise adjust the parking brake, address to the Section Adjustment of the parking brake. 25 Lower the car on wheels. |
