11:20. Removal, recovery repair and installation of wheel cylinders

Details of installation of the wheel cylinder of the drum brake mechanism (Galant model)

1 — the Brake drum
2 — Pruzhina of fastening of a boot to the adjusting lever
3 — the Top coupling spring

4 — Assembly of the automatic regulator
5 — the Brake tube
6 — the Wheel cylinder



1. Details of installation of the wheel cylinder of the drum brake mechanism are shown on an illustration.
2. The car also establish to Poddomkratta it on props.
3. Remove a spring of fastening of a boot to the adjusting lever.
4. Remove the top coupling spring.
5. Remove assembly of the automatic regulator.
6. Prepare drain capacity and disconnect a brake tube from the wheel cylinder.

For an otpuskaniye of a nipple nut, in order to avoid a rounding off of corners of its shlits, it is necessary to use a special cap key with a cutting head, - prepare for collecting the spilled liquid!

7. Turn out fixing bolts and remove assembly of the wheel cylinder from a brake board.

Recovery repair


1. Authors of the present manual recommend to owners of the car to avoid whenever possible restoration of components of the brake mechanism, giving preference to replacement of worn-out knots.
2. In the absence of near at hand replaceable components recovery repair of the wheel cylinder can be executed in a way described below.
3. First of all it is necessary to take care of minimization of risk of hit of dirt to the hydraulic highway of the brake system. Use for addition in system only pure brake fluid, - in case of need wash out all brake path, fill it with fresh liquid and pump over.
4. Remove the wheel cylinder from a brake board and transfer it to a pure workbench.

5. Remove boots and release pistons from the cylinder.

At assembly of the cylinder boots are subject to replacement without fail. Prepare a remnabor.

6. Pistons of the wheel cylinder are equipped with sealing cuffs and rasperta the spring located between them. Take all components from assembly of the cylinder, - in case of need use compressed air. In the absence of access to a source of compressed air it is necessary to show extra care and to try not to damage cylinder mirrors at extraction of components. All components which are included in the package of a remnabor are subject to replacement.

7. Carefully wash out all metal components, including the cylinder case, the denatured alcohol or pure brake fluid.

Do not use for washing of components of the brake mechanism the gasoline, kerosene, solvents and other oil products capable to lead to destruction of rubber sealing components at all.

8. Carefully dry all details (whenever possible with use of compressed air), - in order to avoid hit in the cylinder of pile do not use rags for drying of components.
9. Attentively examine the working surfaces of cylinders. In case of detection of scratches, zadir and other mechanical defects make replacement.

10. Spread out the prepared components as installation them in assembly of the cylinder.

11. Grease mirrors of the cylinder and sealing cuffs of pistons with pure brake fluid.

12. Establish internal cuffs, then fill pistons in the cylinder.

13. Manually, without use of any tools, put boots in reception flutes.



1. Install the cylinder on the regular place on a board of the brake mechanism. Screw fixing bolts and tighten them with the required effort (10 H • м).
2. Connect the brake line to the cylinder, having tightened a cap nut of its nipple connection with effort 15 H • m.
3. Add fresh brake fluid in the GTTs tank and weaken the gate of pumping of the installed wheel cylinder, - liquid will begin to fill the cylinder that will allow to reduce time spent for pumping of a contour later.
4. Establish assembly of the automatic regulator.
5. Establish the top coupling spring.
6. Establish a spring of fastening of a boot to the regulator lever.
7. Install the brake drum.
8. Establish a wheel, lower the car on the earth and pump over a brake contour (see the Section Pumping of the Brake System).
