Toyota RAV4>> Brake system>> Replacement back brake pads
       PREVENTIONS
Necessarily replace all pads on one axis of the car even if one is worn out only колодка. If brake pads will be repeatedly established, before removal mark them.
At work brake pads the dust which contains asbestos, unhealthy is formed, therefore at clearing brake pads do not use compressed air and do not inhale a dust.
For clearing of brake mechanisms use only a special cleaner of brakes.

Each time at replacement brake pads replace returnable and bottom coupling springs as they constantly are exposed to heating and cooling at work of brakes therefore can lose elasticity and not completely take away brake pads from a brake drum.
Not to mix a detail of the left and right back brake mechanisms, replacement brake pads make at first on the one hand, then with another.

Fig. 11.23. Details of the drum-type back brake mechanism: 1 – a protective cover; 2 – the piston; 3 – a cuff; 4 – the prorolling union; 5 – the working brake cylinder; 6 – a spring; 7 – a cuff; 8 – the piston; 9 – a protective cover; 10 – an adjusting lath; 11 – back brake колодка; 12 – the lever of a lay brake; 13 – the S-shaped clip; 14 – the E-shaped lock ring; 15 – the lever of automatic adjustment; 16 – a spring of the lever of automatic adjustment; 17 – a fixing spring pads; 18 – elements of fixing brake pads; 19 – the bottom coupling spring; 20 – a returnable spring; 21 – a lobby brake колодка


The device of the back drum-type brake mechanism is shown on fig. 11.23.
Block forward wheels an emphasis.
Loosen the nuts of fastening of a back wheel. Lift a back part of the car and establish it on support.
Release the lever of a lay brake.
Remove a back wheel.
Marker or paint note mutual position of a brake drum and a nave that at installation of a brake drum balancing was not broke.

Fig. 11.24. Reduction of length of an adjusting lath for tap brake pads from a brake drum


From an underside of a protective casing of a back brake remove заглушку and through opened aperture a screw-driver and a hook rotate a cogwheel of an adjusting lath for reduction of length of an adjusting lath therefore brake pads will depart from a brake drum (fig. 11.24). Remove a brake drum.
Clear brake pads with use of a special liquid and dry up them.

Fig. 11.25. Removal of a returnable spring from a lobby brake pads


Screw-driver edge remove a returnable spring from a lobby brake pads (fig. 11.25).

Fig. 11.26. Removal of a plate of a spring of fixing of a lobby brake pads


Remove a plate of a spring of fixing of a lobby brake pads, having pressed a plate and having turned it on 90 (fig. 11.26).
Remove a lobby brake pad and disconnect from it the bottom returnable spring.
Remove a plate of a spring of fixing back brake pads, having pressed a plate and having turned it on 90 .

Fig. 11.27. A detachment of a cable of a lay brake from the lever on back brake колодке


Disconnect a cable of a manual brake from the lever on back brake колодке (fig. 11.27).
Remove back brake pad together with an adjusting lath.

Fig. 11.28. Removal of a returnable spring with back brake pads


Disconnect a returnable spring from back brake pads and remove its and adjusting lath (fig. 11.28).

Fig. 11.29. A detachment of a spring of the lever of automatic adjustment from back brake pads


Disconnect a spring of the lever of automatic adjustment from back brake pads (fig. 11.29).
Remove an adjusting lath with back brake pads.

Fig. 11.30. Removal of the S-shaped clip of fastening of the lever of automatic adjustment to back brake колодке


Remove the S-shaped clip and separate the lever of automatic adjustment from back brake pads (fig. 11.30).

Fig. 11.31. Removal of a lock ring of fastening of the lever of a lay brake to back brake колодке


Remove a lock ring and separate the lever of a lay brake from back brake pads (fig. 11.31).

Fig. 11.32. Выбивание a pin from old back brake pads


Beat out a pin from old back brake pads and establish it on new pad (fig. 11.32).
Establish the lever of a lay brake on a pin back brake pads and fix its new E-shaped lock ring.
Establish the lever of automatic adjustment on a pin back brake pads and fix its new S-shaped lock ring.
Establish a spring of the lever of automatic adjustment.

Fig. 11.33. Installation of an adjusting lath on back brake pad


Establish an adjusting lath on back brake pad, then hook on a returnable spring for an aperture pads (fig. 11.33).
Apply a thin film high-temperature greasing on a protective casing of a back brake in places of its contact with brake колодками.
Establish a cable of a manual brake on the lever of a manual brake.
Establish back brake pad into place, pass through pad a pin, establish a spring and fix a spring a plate, having pressed a plate and having turned it on 90 .
Establish on pads the bottom returnable spring, then establish a lobby brake pad into place, pass through pad a pin, establish a spring and fix a spring a plate, having pressed a plate and having turned it on 90 .
Fix the top returnable spring on a lobby brake колодке.
Being careful, clear an internal surface of a brake drum of a brake dust and a dirt. Clear an external surface of a brake drum and check up on obvious signs of deterioration or damages, presence of cracks round apertures under bolts of fastening of a wheel. If necessary replace a drum. Measure internal diameter of a brake drum. Value of as much as possible admissible internal diameter of a brake drum is put on an internal flange of a drum.
Establish a brake drum on a nave of a back wheel. A screw-driver inserted through an aperture from an underside of a protective casing of a back brake, rotate a cogwheel of an adjusting lath while brake pads will not brake a brake drum, then turn in the opposite direction a cogwheel on so much that the brake drum rotated freely. Заглушкой close an aperture in a protective casing of a back brake.
Establish a wheel and fix its nuts.
Lower the car.
Some times tighten the lever of a lay brake to adjust position back brake pads.
