Ok guys, I browsed on Mity-vac website and found some info on where to start first when bleeding the brakes.

Q: What is the proper sequence in which to bleed my brakes when using the Mityvac® pump for vacuum brake bleeding?

A: When using the vacuum bleeding method to bleed brake systems on vehicles which are rear wheel drive the sequence should start with the wheel closest to the master cylinder and end with the wheel which is farthest from the master cylinder.

Example: LF wheel, RF wheel, LR wheel, RR wheel

However, when vacuum bleeding brake systems on vehicles which are front wheel drive the sequence will change. These systems use a diagonal configuration for safety purposes. On this system the sequence should start with the wheel closest to the master cylinder as before, however the next wheel in the sequence will be diagonally aligned with that wheel.

Example: LF wheel, RR wheel, RF wheel, LR wheel.
LF - Left Front RF - Right Front
LR - Left Rear RR - Right Rear


Q: When I try to bleed my brake system using the Mityvac® pump I am getting air bubbles in the line connected to the bleeder screw on the wheel cylinder and little or no fluid is being collected in the reservoir jar. I have tried several times to bleed my brakes without success. What is the cause of this problem?

A: Usually this condition is caused by a small amount of air being pulled between the threads of the bleeder screw and the body of the wheel cylinder or caliper resulting in the appearance of several small bubbles in the line connected to the bleeder screw. This can be corrected quickly and easily. Before you begin to bleed the brake system we suggest that the bleeder screws be removed at all four wheels. With the bleeder screws removed assure all are clean and the passages of the bleeder screws are free of corrosion or debris. (A small paper clip will work well.) Next, be sure that all brake fluid, penatrating oil, and or grease is removed from the bleeder screw. (Brake cleaning solvent does an excellent job.) Apply a 2 to 3 inch piece of Teflon® tape to the threaded area of the bleeder screw only. Wrap the tape in the opposite direction of the rotation of the threads. This will prevent any see page of air from around the threads. Install each bleeder screw back into the corresponding caliper or wheel cylinder and lightly seat the bleeder screw. Now you are ready to begin bleeding the brake system! This may seem like quite a bit of work in the beginning, but, once you get started it should only take minutes to complete. In fact, the procedure outlined above is an important step when bleeding brake systems regardless of the method used. It is critical to be sure that each component in the brake system is in proper working order to assure a long lasting repair. Remember, the brake system is the most important system in your vehicle. If the brake system fails to perform correctly, the results could be disastrous.

just to clarify, i'm assuming that guide's for the US left hand drive cars?
so in right hand drive configurations it would be:
front right(driver)
rear left(passenger)
front left(passenger)
rear right(driver)

This option is applicable for EK9 with ABS?

last i did buy the repair kit for front and rear caliper.
I had no vacuum and no one to pump on the brake pedal to help me bleed my brake.

I decided to open all 4 brake lines and lett the brake fluid run for a while and I kept filling the mastcylinder.

After 5 minuts with the mastcyl full i closed all 4 lines starting from FR-wheel RL-wheel FL-wheel and last the RR-wheel as Im driving a RHD

At the end my brake presure was very low, the pedal goes deep. But I kept on driving like that, and everytime i feel it was getting better. After 3 day's it was 100% ok
