Checks of the brake system
Signs of malfunctions in the 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. At the same time slips should be changed immediately, otherwise brake disks will be damaged and they will need expensive repair.
2 Any of the listed below signs can indicate potential defect of the brake system:
a) When squeezing a pedal of a brake the car "takes away" in one party
b) Brake mechanisms when braking make the scraping or squealing sounds
c) The pedal of a brake has the excessive course
d) The pedal of a brake pulses (it normally only during the work of the ABS system)
e) Leak of brake fluid is observed (usually on inside of the tire or a wheel)
3 In case of detection at least of one of these signs immediately examine the brake system.
Brake lines and hoses
4 Park the car on the flat platform and switch off the engine. Take off caps from wheels. Weaken, but do not remove bolts of fastening of all four wheels.
5 The car and reliably establish to Poddomkratta it on support.
6 Remove wheels (address the Section Rotation and replacement of wheels).
7 Check all brake lines and hoses for existence of cracks and attritions in their external covering, leaks, swellings and deformations. Check brake hoses in forward and back parts of the car for existence of signs of a softening, cracks, deformations or wear as a result of friction about other components. Check all nipple connections for 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 car design elements at the same time.
10 At detection of leak of liquid or their damages it is necessary to eliminate immediately. For more detailed description of the procedure of repair of the brake system address the Head the Brake system.
Check of thickness of brake shoes
At wear of brake shoes of forward and back brakes on the dashboard the signaling device lights up. At the same time 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 the balanced 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 caliper. At achievement of a limit of wear of a block it is necessary to replace. At the same time 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 leak of brake fluid. With leakage urgently take a support to repare.
16 Visually check brake disks from the internal and external parties for existence of zadir, corrosion damages and cracks. If necessary replace disks.
18 If the limit of wear is reached, blocks need to be replaced. Surely replace all blocks of one axis, address 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 lubricant the aligning wheel disk belt on a nave. Do not grease bolts of fastening of a wheel. Rusty bolts need to be replaced. 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 brake with the 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 slow down the car the parking brake from the speed of 40 km/h on the desert street or the parking lot so. Without changing speed, tighten the parking brake on one tooth and pass 400 more m. Release a brake and let's it be cooled.
21 Lift and establish a back part of the car on supports. Wheels have to be above the ground at the height not less than 2 cm.
22 Tighten the parking brake on one click and turn back wheels. Wheels have to be turned freely, brakes should not work.
23 At raising of a brake on 10 clicks of a wheel have to slow down completely.
24 Otherwise adjust the parking brake, address the Section Adjustment of the Parking Brake.
25 Lower the car on wheels.
