Checks of brake system
Signs of malfunctions in brake system 1 Disk brake mechanisms can have the built in indicators of deterioration of frictional overlays which signal that deterioration of overlays has reached critical size. Thus overlays should be changed immediately, differently brake disks will be damaged also by it expensive repair is required. 2 Any of listed below signs can specify in potential defect of brake system: a) At squeezing of a pedal of a brake the car "withdraws" in one party b) Brake mechanisms at braking publish scraping or squealing sounds c) the brake Pedal has an excessive course d) the brake Pedal pulses (it normally only at system ABS work) e) leaks of a brake liquid (usually on a tyre 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. Ослабьте, but do not remove bolts of fastening of all four wheels. 5 Poddomkratte the car and reliably establish it on support. 6 Remove wheels (address to Section Rotation and replacement of wheels). 7 Check up all brake lines and hoses on presence of cracks and attritions in their external covering, leaks, swellings and deformations. Check up brake hoses in forward and back parts of the car on presence of signs of a softening, cracks, deformations or deterioration as a result of a friction about other components. Check up all штуцерные connections on presence 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 leaks of a liquid or their damages it is necessary to eliminate immediately. For more detailed description of procedure of repair of brake system address to the Head Brake system. Check of a thickness brake колодок At deterioration brake колодок forward and back brakes on the panel of devices the signalling device lights up. Thus it is necessary to replace urgently brake колодки.
11 Mark a paint position of wheels concerning a nave. It will allow to establish at assemblage отбалансированные wheels in their former position. Ослабьте 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 колодки and measure a thickness by a calliper. At achievement of a limit of deterioration колодки it is necessary to replace. Thus it is necessary to replace all four колодки one axis even if a deterioration limit one has reached only колодка.
15 Check up, whether has a support of traces of leaks of a brake liquid. At presence негерметичности urgently hand over a support in repair. 16 Visually check up brake disks from the internal and external parties on presence задиров, corrosion damages and cracks. If necessary replace disks. Lay brake
18 If a deterioration limit will reach, колодки it is necessary to replace. Necessarily replace all колодки one axis, address to Section Removal and installation колодок a lay brake. 19 Establish wheels so that the marks put at removal have coincided. Preliminary grease with a thin layer подшипниковой greasings 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 100 Н•м. Check of functioning of a lay brake The lay brake represents a drum-type brake with тросовым a drive. The drum is built in disks of a back brake. As deterioration brake колодки a lay brake is insignificant, corrosion damage or pollution brake колодок can take place. Therefore before check of a lay brake it is recommended to earn extra it as follows: 20 Smoothly brake the car a lay brake since speed of 40 km/hour in deserted street or a parking platform so. Without changing speed, tighten a lay brake on one tooth and pass 400 more m. Release a brake and allow to it to 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 a lay brake on one click and turn back wheels. Wheels should be turned freely, brakes should not work. 23 At brake raising on 10 clicks of a wheel should затормаживаться completely. 24 Otherwise adjust a lay brake, address to Section Adjustment of a lay brake. 25 Lower the car on wheels. |
