Repair of the wheel brake cylinder

If it is not required to replace the wheel cylinder, it can be disassembled in the established condition. Previously it is necessary to remove brake shoes. The latest it is necessary to replace the wheel brake cylinder when brake liquid gets through cuffs. At replacement of brake shoes it is necessary to remove always from the cylinder boots and to look in the cylinder. If behind boots it is damp or all wheel cylinder is covered with brake liquid, to replace the cylinder. Besides replacement is necessary, if pistons in the cylinder slide hardly, there are grooves or a rust. In one of these cases the wheel or not затормаживается, or is braked constantly.

1 — boots
2 — pistons
3 — cuffs of pistons
4 — caps

5 — a spring
6 — a rubber cap
7 — the pumping gate
8 — a steel ball

Removal

 PERFORMANCE ORDER

  1. To remove brake shoes.
  2. To remove boots a screw-driver. Carefully, not to damage caps.
  3. To take out both pistons with cuffs.

Thus can flow out a little brake liquid, enclose a rag. To take out a spring.

  1. To remove cuffs from pistons, thus not to damage pistons.
  2. To wipe the cylinder from within a pure rag. On a working surface there should not be grooves and a rust, if necessary the cylinder to replace.
  3. To clear all elements alcohol or brake liquid. To observe instructions according to the treatment of brake liquid.

Not to apply liquid on the basis of mineral oils, such as gasoline or kerosene, otherwise can arise malfunctions in brake system.

Installation

 PERFORMANCE ORDER

  1. To unscrew the pumping gate, it is possible to replace. Thus not to lose a steel ball.
  2. If laying is replaced, it is obligatory to use all repair kit.
  3. To put on cuffs pistons so that sealing edges were turned in the direction of forcing of liquid.
  4. To cover both pistons and a working surface of the cylinder with special greasing for brake cylinders, for example, ATE firms.

Not to use former greasing, differently brake liquid will be polluted.

  1. To insert into the wheel cylinder the left piston.
  2. To insert a spring on the right and the right piston.
  3. To put on boots.
  4. To establish brake shoes and a brake drum.
  5. To pump over brake system. Thus, as a rule, it is enough to pump over only that cylinder where pipelines were opened. If after pumping brake pressure floats, it is necessary to pump over all system.
  6. Several times strongly to squeeze out a brake pedal. It regulates back brakes.
