Check of a condition and replacement of brake hoses and lines

Condition check

Each half a year, поддомкратив the car and having established it on props, check the rubber brake hoses connecting steel lines to assemblies of lobbies and back brake mechanisms on existence of cracks, protertost of external covers, signs of leaks, swellings and other damages. Hoses are important and vulnerable components of brake system and should look round on all length. Carrying out such check will be helped by small lamp and pocket mirror use. In case of identification of any of listed above defects the hose is subject to immediate replacement.

Replacement

Forward brake hoses

 PERFORMANCE ORDER

  1. Disconnect the brake line of the union of a hose, try not to bend thus an arm or the line. If there is such possibility, use for an otdavaniye of cap nuts of shtutserny connections a special key.
  1. For removal of a forward brake hose give from its union the brake line - use a special key for an otdavaniye of cap nuts of fastening of metal lines; then отболтите a hose from a frame, having used for this purpose a head of the TORX type or a screw-driver.
  1. By means of a TORX type or screw-driver head отболтите a hose from a frame.
  2. Give a hollow bolt of shtutserny knot of fastening of a hose to a support of the brake mechanism (see an illustration) and disconnect a hose from a support. Throw out sealing washers.
  3. At installation first of all connect a hose to a support, replace sealing washers from both parties of the union. Tighten an entrance bolt of shtutserny connection with demanded effort.
  4. Without overwinding a hose, connect to its union the brake line, however do not tighten while a nut of shtutserny connection.
  5. Establish a bolt of fastening of a hose to a frame and reliably tighten it.
  6. Strongly tighten shtutserny connection of a hose with the line.
  7. After completion of installation of a brake hose it should not appear overwound. Make sure that the hose anywhere does not touch to any moving components of a suspension bracket - for this purpose ask the assistant to turn several times a steering wheel from an emphasis against the stop. In case of need make correction of installation of a hose. Pump over brake system (The section Pumping of brake system).

Back brake hoses

 PERFORMANCE ORDER

  1. By means of two keys disconnect a hose from an arm on a frame - watch to deforming an arm or steel lines.
  2. By means of flat-nose pliers remove an U-shaped clip and disconnect a reception half of the shtutserny socket from an arm.
  1. For a detachment of a brake hose from the metal line distribute two shtutserny connections equipped by a carving (in order to avoid a provorachivaniye of one of them when untwisting another use the second wrench), then by means of flat-nose pliers or бокорезов (diagonal nippers) remove an U-shaped clip.
  1. Disconnect two hydraulic lines from the connecting block, then отболтите and remove a hose.
  2. To Priboltita the connecting block to a bridge case, then connect lines, having strongly tightened their shtutserny connections. Without overwinding a hose, fix a reception half of its shtutserny connection in a frame arm.
  3. Establish an U-shaped clip of fixing of the reception end of a hose in an arm.
  4. By means of pair of wrenches connect steel lines to reception half of shtutserny connections. Again watch to bending an arm or the steel line.
  5. Make sure that in the course of installation of a hose there was no weakening of fastening of an arm of a frame. In case of need tighten fixture.
  6. Fill in in the tank of the main brake cylinder liquid and pump over system (The section Pumping of brake system).

Metal brake lines

At replacement of brake lines special attention give designs and manufacturing techniques of replaceable components. At all do not establish in contours of brake system copper tubes. Only steel tubes acquired in dealer office or firm shop of auto parts suit.

It is preferable to get brake lines with already razvaltsovanny end faces and equipped with shtutserny connections. To such lines if they are bought under concrete model of the car in dealer office or are ordered in firm shop, the corresponding form is usually already given.

At installation of the new line take care of reliability of its fastening in arms and about that between it and moving or strongly warmed up components of a suspension bracket and system of production of the fulfilled gases there was a sufficient gap.

On termination of installation check liquid level in the tank of the main brake cylinder, in case of need make having added. Pump over brake system (The section Pumping of brake system) and, before starting car operation, carefully check serviceability of functioning of brakes.
