Replacement pads disk brake mechanisms
Essentially on the right or at the left it is necessary to replace both pads. It is possible to apply only pads with the General admission to operation (in German Allgemeine Betriebserlaubnis – ABE).
|
|
Brake mechanism Girling: to turn out only the bottom fixing bolt (2) cases of a support of the disk brake mechanism. To hold направлящий a bolt. The top fastening (1) remains untouched. At installation to apply new самоконтрящийся a fixing bolt! |
|
|
Brake mechanism Ate: after removal of a cap (3) to weaken the bottom bolt with internal шестигранником in protective plugs (4). |
In the brake mechanism of manufacturer Girling two are necessary for replacement pads in total new самоконтрящихся a bolt. In most cases they enter into a set with brake колодками – to check up! If the brake mechanism from manufacturer Ate bolts be not required to you.
As pistons in supports of brake mechanisms with increasing deterioration pads leave all further before installation new, thicker pads it is necessary to put them into place. Thus the brake liquid is squeezed out through the pipeline in a receiver. If in the past the excessive quantity of an unnecessary liquid this surplus now needs to be pumped out has been added. Otherwise the acting brake liquid will spill on the metal details located in a motor compartment. It is necessary to apply to pumping out only absolutely pure pipette or an old medical syringe – at all do not suck away a mouth!

- The car to raise in front and to fix.
- To remove a wheel.
- To turn a steering wheel that it was possible to reach easily to pads.
- Brake mechanism Ate: to remove a cap on an inside скобы. To insert a face key in opened now internal шестигранник a bolt and to weaken it.
- To turn on only the bottom bolt.
- To extend a bolt, to cast away bracket a support of the disk brake mechanism upwards or – if both bolts have been removed – to remove.
- Removed bracket to suspend on a wire to an amortisation rack.
- Brake mechanism Girling: to unscrew only the bottom fixing bolt of the case of a support of the disk brake mechanism, holding thus directing bolt for шестигранную a head.
- To cast away bracket upward.
- Both versions: on the right and at the left to take out pads from directing tyres.
- By means of a clamp to wring out a rod inside. That the piston has not warped or damaged, put on a lock ring a small plate.
- At the two-piston brake mechanism it is necessary same way to wring out both brake rods together or separately.
- Pay attention to correct landing of a heat-shielding guard in the piston cylinder.
- To establish new pads.
- To put into place a support.
-
Brake mechanism Ate: to tighten directing bolt the moment 25 Nm and again to put on a cap.
-
Brake mechanism Girling: to tighten bottom (the new!) a fixing bolt the moment 35 Nm. The top bolt not дозатягивать, differently will stop самоконтрящееся action. Hold directing bolt thin рожковым with a wrench, differently it will clamp, and in this case force of an inhaling will be incorrect.
- After assemblage some times press a brake pedal, until then while pads will not nestle on brake disks. Otherwise there will be no brake influence!

The help: at passage of the first 500 km with new brake колодками brake whenever possible more cautiously. |
Removal of a forward support of the disk brake mechanism
Двухпоршневый the disk brake mechanism with floating bracket 6-cylinder models
|
|
(1) 4-cylinder models will cast away the case of a support of the disk brake mechanism upwards after removal of the bottom fastening (4). Колодки (3) for the present stand in the directing. Further are visible:
2 – a heat-shielding guard in the brake piston;
5 – a brake disk;
6 – a support of the brake mechanism. |
Each of forward supports of disk brake mechanisms is strengthened on an amortisation rack by two so-called рефлеными bolts. At these bolts for шестигранной a head the corrugated surface preventing casual easing or loss of a bolt is located. These рефленые in no event it is impossible to replace bolts usual!

- To remove a wheel.
- To remove brake pads.
- To weaken fixing bolts of a support of the brake mechanism.
- To hang out a support of the brake mechanism with the connected hose so that a hose has not been tense.
- Or to remove a brake hose or a tube.
- To press a pedal of a brake and to hold it, to prevent вытекание a brake liquid.
- Before installation to clear corrugated surfaces of ridge bolts.
- To tighten corrugated bolts the moment 125 Nm.
- Again to establish a brake hose or a tube.
- To remove air from brake system, in a case if the brake pipeline or a hose has been removed.
- Before a start of motion some times to press a brake pedal until the normal course of a pedal will be established.

Replacement of cuffs of brake pistons
|
|
On an illustration the piston of the cylinder of the disk brake mechanism move by means of a clamp that it was possible to establish new brake pads. For protection we have enclosed a small wooden plate. The support of the brake mechanism of manufacturer Girling made for a photo usually remains fixed on the top bolt. |
If the cuff of the brake piston in a support of the disk brake mechanism has been damaged, you need to replace as soon as possible it, differently the brake piston soon will begin заедать because of a dirt and corrosion. The cuff can be got only complete with a sealing ring of the brake piston. For installation of both details it is necessary to take the piston from the case of the brake cylinder.
It is for safety reasons better to charge this work of a workshop. For example, to remove a support of the disk brake mechanism and to bring it to a workshop.
Replacement of a forward brake disk
Brake disks need to be changed from both parties simultaneously. Unilateral replacement will lead to non-uniform brake action.
|
|
- To disconnect a support of the disk brake mechanism and to strengthen its wire on a body; hoses remain connected.
- To turn out a bolt with crosswise шлицем (near to an aperture for wheel bolts).
- To process a bolt means for removal of a rust or to apply pulse болтоверт.
- Now it is possible to remove a hand a brake disk from a wheel nave.
- If it приржавел to help sharp blows of a hammer but only in the event that this disk in any case should vary.
- Before installation of a new brake disk to clear a surface прилегания on a wheel nave.
