Ross-tech Bleeding Issue 9N3

Gravity bleeding


Replaced my brake fluid today using a power bleeder, and noticed a lot of positive comment on the web about gravity bleeding as an alternative - slow but effective was the pevailing view. Also it apparently works well with ABS systems.

Ayone tried this? Opinions?

Cheers.

Ross-tech Bleeding Issue 9N3

When I changed my rear rotors and pads after buying my Polo two months ago. I bled the brakes with a motive bleeder without any issues. I didn't introduce any air into the system and my main reason for bleeding was to change the fluid.

Here is a picture of the motive bleeder. My wife was happy to buy it for me after years of having to pump the pedal.

Brake Fluid Change Procedure

When I changed my rear rotors and pads after buying my Polo two months ago. I bled the brakes with a motive bleeder without any issues. I didn't introduce any air into the system and my main reason for bleeding was to change the fluid.

Here is a picture of the motive bleeder. My wife was happy to buy it for me after years of having to pump the pedal.

I replaced the front brake lines with ECS Tuning braided lines.

Safety first:

Make sure you wear disposable gloves and safety glasses.
Raise the car and rested it securely on jack stands.

Drivers side:

Place a container under the wheel. Undo top brake hose nut a little, then undo bottom hose a little brake fluid will start to come out but not a lot.
Relese midle "c" clump, make sure you have enough fluid in the reservoir.
Remove nut from top hose and C clump as well the bottom nut, retrieve the old hose from the system and place it in the container.

Ready to install the new lines.

Start from the bottom side first all the way to the top, make sure all fittings are properly done...no short cuts here.

Passenger side:

Same as drivers side.

Brake System Bleeding Procedure:

Check brake fluid is full.
Get an assistant.

Start the engine and make sure is in Neutral(ovious).

At this stage the brake pedal will go all the way to the floor, have the assistant pump the brake pedal a few times to get a good pressure in the system, then depress the pedal firmly and hold it down.
Locate the bleeder valve and open it enough to allow a flow of fluid to leave the valve; the pedal will sink. watch out for air bubbles to exit the submerged end of the tube, repeat 5 times per side until no bubbles appear.Be sure to check the fluid level in the master cylinder reservoir frequently.

At the end of the operation refill the master cylinder reservoir to the horizontal seam.

Check the operation of the brakes. The pedal should feel solid

Go for a test to make sure everything is as it should be.

Hope this helps.
Enjoy your motoring.
