As one pump the brakes ?

Bleeding brake system of the car must be made hydraulic planning, when changing the oil, and after each work with the braking system, whether it tuning, repair or replacement of consumables.Typically, pumped the brakes car repair, because it is simple and inexpensive service, and dirty brake fluid do not want anyone.But if you are a pleasure to service your car yourself, or go to a car wash just not possible - pump the brake can be independently and, as we have already mentioned here.But it does not always have a friend nearby ready to help, and then have to cope yourself.Here are two ways how one pump the brakes.

method first

Preparation

For the first method, you need the following:

  • capacity to drain old brake fluid (suitable half-liter bottles or cans)
  • hose suitable for fitting
  • diameter pumping clean rag to clean the nozzles
  • Guideoperating a vehicle
  • new brake fluid with a margin
  • WD-40 (in case the brake bleeder valve soured)
  • key to pump the brakes or conventional open-end wrench to unscrew the nozzles (a special key for the fittings will save up faces with taut during fitting)

instead assistant will need to find a reliable stop for the brake pedal.Will suit any piece of wood, or anti-theft steering wheel lock.The bollard can be inserted between the brake pedal and the driver's seat.

Bleeding

Look brakes pumping scheme for your car's instruction manual.If the scheme or guidance is not available, follow the standard procedure of pumping the brake channels, starting with the long wheel from the brake master cylinder (GTZ).Typically, the far - right rear, respectively, the procedure is as follows: right rear, left rear, right front, left front.

  1. GTZ Fill the tank with new brake fluid up to the mark and seal it with a lid.
  2. Check that all fittings freely unscrewed.If not - soak soured fittings WD-40 and wait until they otkisnut.
  3. Clean fittings from dirt with a clean cloth.
  4. Put the hose on the first, farthest from the GTZ connector at one end, a second dip in the prepared drain capacitance.
  5. few times push the brake pedal, depress it to the floor and lock the brace: how you will create in the brake hydraulic circuit high pressure that would push through choke the old brake fluid with air.
  6. Unscrew the nipple to the capacity of the system was the old brake fluid to flow with bubbles.Wait for exit of air bubbles from the channel.
  7. When the liquid begins to flow without bubbles, tighten the fitting.
  8. Repeat the previous manipulation of the three remaining fittings in order.If brake fluid ceases to flow through the nozzle - then the pressure fell on the system.In this case, you need to tighten the fitting and press the brake pedal a few times, just fixing it then strut.

During pumping systems do not forget to follow the brake fluid level in the master cylinder reservoir and keep it filled.If the tank is empty, air will be able to get there by pressing the brake pedal to the system.

Method two

Preparation

You will need:

  • lid tank coupling with a rubber mat (available at auto parts store)
  • valve of tubeless tires without tappings (nipple)
  • sealant
  • hose suitable for valve
  • diameter
  • hose suitable for fitting pumping diameter drain
  • new brake fluid with a margin
  • manual
  • car with a clean cloth to clean the nozzles
  • capacity to drain old brake fluid
  • WD-40
  • key to pump the brakes or conventionalopen-end wrench to loosen fittings
  • pumped up to 2 atmospheres spare wheel or a compressor for pumping into the tank GTZ air

Unlike the previous method, increased pressure in the system is created not by pressing the brake pedal, and by injecting air into the tank of the maina brake cylinder.For pumping the air you have to make a special cover of the tank.

  1. Drill purchased in the clutch reservoir cover hole diameter of ~ 11-12 mm.
  2. Insert the valve hole of a tubeless tire and fix it on the cover of the sealant.
  3. Allow the sealant to harden.
  4. Put one end of the hose to the valve.

Bleeding

Look brakes pumping scheme for your car's instruction manual.If the scheme or guidance is not available, follow the standard procedure of pumping the brake channels, starting with the long wheel from the brake master cylinder (GTZ).Typically, the far - right rear, respectively, the procedure is as follows: right rear, left rear, right front, left front.

  1. GTZ Fill the tank with new brake fluid to level and close it with the hose cover.
  2. free end of the hose nipple put on the spare wheel and drag the wire so it is not poisoned air / connect with the compressor.
  3. Check that all fittings available otkruchivayutsya.Esli not - soak soured fittings WD-40 and wait until they otkisnut.
  4. Put the drain hose to the first, farthest from the GTZ connector at one end, a second dip in the prepared drain capacitance.
  5. Untie the wire and straighten the hose to the air from the tires began to flow into the tank GTZ / switch compressor (pressure required from a half to two atmospheres).
  6. Unscrew the nipple to the capacity of the system was the old brake fluid to flow with bubbles.
  7. When the liquid begins to flow without bubbles, tighten the fitting.
  8. Shut off the air pressure in the tank GTZ
  9. Repeat the previous manipulation of the three remaining fittings in order.

As with the first method, it is important to monitor the level of brake fluid in the master cylinder reservoir and, if necessary, pour new.

Both of these methods are suitable not only for pumping (bleed air from the brake system), but also for the rinsing circuit brake system and complete replacement of the old to the new brake fluid.To replace the fluid in the system, while leveling and draining the old fluid, wait for each of the union not will flow a new, clean liquid.New fluid can be distinguished by color and texture.

remind you that if, after pumping the brake pedal system anyway gives "soft" move, it is a chance for the diagnosis of the braking system.The reason for such behavior of pedal wear pads or discs can be.
