Hi,

I know many cars with ABS, that need tester connected, to give a command for bleeding brakes, and then the ABS pump works always to be

able to change the old brake fluids.

My method:
start engine, idle, open reservouir cap, open bleed valve on FR wheel rotor, someone press a bit pedal, and i open-close bleeding nut, till new fluid comes to sight.

I didn't do it, but i believe it needs to work, to have servo, and for ABS pump not cuting fluid draining.

If anyone has done it right, please inform me, cause i don;t want to go to hyundai dealer.

good answer,

but i mean that i need to change ALL the brake fluids, cause my car, with auto getrieben is based 100% ONLY on brakes. So , after so many years, noone changed them.

I have the feeling that i cannot press the pedal many times with ABS, motor off, so i cannot bleed all the fluid till new fluid comes to bleeders.

When i change brake pads, i do the same trick as you.

but 1998 model, till today, 13 years, noon changed them.

mistake

OFFICIAL WORKSHOP MANUAL PROCEDURE

93-50-014 ABS AIR BLEEDING PROCEDURE

When any work is performed on the brake hydraulic system or if air is suspected to be in the hydraulic system, the brake system must be air bled. Sonatas equipped with ABS must be bled in two steps as follows:
STEP 1
CAUTION
Always use a bleeder hose when bleeding the modulator. The brake fluid may still be pressurized in the accumulator, and could damage your eyes or skin if you open a bleeder port without first attaching a bleeder hose.

* After working on the brake system, check all brake lines and fittings for proper installation. First bleed in the conventional manner, as outlined in the applicable shop manual. It is important to bleed the brake system in the following sequence:

1 - Left Rear
2 - Right Front
3 - Right Rear
4 - Left Front
STEP 2

Air bleed the ABS modulator using the following steps:

* Connect the MUT with the correct ROM and system pack. The connector is located in the fuse box at the lift kick panel.

* Turn the ignition key to the "ON" position to confirm that the MUT is "ON" ( do not start the engine ).

* Attach the bleeder hose to the RF/LR sump bleeder port and submerge the opposite hose end in a clean container partially filled with brake fluid (use only DOT 3 grade fluid ).

1 - RF/LR SUMP
2 - LF/RR SUMP
3 - RF/LR ACCUMULATOR
4 - LF/RR ACCUMULATOR

* With the help of an assistant, apply light and constant pressure to the brake pedal, or use a pressure bleeder.

* Operate the RF B/D valve by using the MUT as follows:
o
Select "Actuator Test" number 3
from the MUT menu.
o
Input code number 43
(refer to page 4, on the MUT sequence table).
o
Push "YES"
on the MUT.

Slowly open the bleeder port 1/2 to 3/4 of a turn and allow fluid to flow out until no air is seen in the fluid.

SEE SEQUENCE TABLE BELOW
CAUTION
NEVER OPEN BLEEDER SCREW WITHOUT FIRST ATTACHING BLEEDER HOSE, AS FLUID CAN FLOW OUT AT A HIGH PRESSURE.
NOTE
Even though the brake pedal may drop slightly as the solenoid valve closes, continue to apply medium pressure to the brake pedal. If the brake pedal needs to be re-pressed, dose the bleeder port first and than release and re-apply pressure to the brake pedal.

* Stop the operation of the actuator by entering "99"
and pushing "YES"
on the MUT.

* Operate the LR B/D
valve in the modulator by entering code number "41"
in the MUT.

* Repeat steps 6 and 7.

* Close the bleeder port and remove the bleeder hose.

* Tighten the bleeder plug screw. Torque: 5-6 Nm (50-60 kg. cm, 43-52 lb in)

* Bleed the air from the other port (LR/RR
sump. RF/LR
accumulator and LF/RR
accumulator) using the above procedures and the following table:

Have you also santamo?

Have you done this like the way you tell?

If you have done it, then yes i will do so.

Also, if you could please the tell me the procedure more precise.

thanks.
